Many microscopic aquatic animals, and some that are larger but inactive, can absorb adequate oxygen through the entire surface of their bodies, and so can respire adequately without a gill. However, more complex or more active aquatic organisms usually require a gill or gills.
Gills usually consist of thin filaments of tissue, branches, or slender tufted processes that have a highly folded surface to increase surface area. A high surface area is crucial to the gas exchange of aquatic organisms as water contains only 1/20 the dissolved oxygen that air does.
With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians.
Note that, contrary to some misconceptions, gills do not break up water molecules into hydrogen and oxygen, but instead absorb the oxygen that is dissolved in the water.
The gills of other insects are tracheal, and also include both thin plates and tufted structures, and, in the larval dragon fly, the wall of the caudal end of the alimentary tract (rectum) is richly supplied with tracheae as a rectal gill. Water pumped into and out of the rectum provides oxygen to the closed tracheae. Aquatic insects use a tracheal gill, which contains air tubes. The oxygen in these tubes is renewed through the gills.
The physical gill mechanism allows aquatic insects with plastrons to remain constantly submerged. Examples include many beetles in the family Elmidae, aquatic weevils, and true bugs in the family Aphelocheiridae.
The gills of vertebrates typically develop in the walls of the pharynx, along a series of gill slits opening to the exterior. Most species employ a countercurrent exchange system to enhance the diffusion of substances in and out of the gill, with blood and water flowing in opposite directions to each other. The gills are composed of comb-like filaments, the gill lamellae, which help increase their surface area for oxygen exchange.
When a fish breathes, it draws in a mouthful of water at regular intervals. Then it draws the sides of its throat together, forcing the water through the gill openings, so that it passes over the gills to the outside. Fish gill slits may be the evolutionary ancestors of the tonsils, thymus gland, and Eustachian tubes, as well as many other structures derived from the embryonic branchial pouches.
A smaller opening, the spiracle, lies in front of the first gill slit. This bears a small pseudobranch that resembles a gill in structure, but only receives blood already oxygenated by the true gills.
Most sharks rely on ram ventilation, forcing water into the mouth and over the gills by rapidly swimming forward. In slow-moving or bottom dwelling species, especially among skates and rays, the spiracle may be enlarged, and the fish breathes by sucking water through this opening, instead of through the mouth. The word branchia comes from the Greek , "gills", plural of (in singular, meaning a fin).

Johnny Gill (born May 22, 1966) is an American R&B; singer-songwriter best known for his romantic ballads and as a member of New Edition. His signature song "My, My, My" has been included on numerous romantic compilations.
Gill began a new chapter in his career in 1987, when he was recruited by Michael Bivins to join New Edition to be the replacement for lead singer Ralph Tresvant, who was rumored at the time to be leaving to pursue a solo career.
With Gill, the oldest member, as one of the lead singers (along with Tresvant, who ended up staying with New Edition and delaying the launch of his solo career) on the album Heart Break, the group developed a more mature, adult sound, hitting the charts with songs such as "Can You Stand The Rain," "N.E. Heartbreak," "If It Isn't Love," and the Gill-led "Boys To Men."
Continuing his role as a romantic balladeer while emerging as a New Jack Swing star, he released a second self-titled album in 1990 which included the hits "My, My, My," "Rub You the Right Way," "Fairweather Friend" and "Wrap My Body Tight". In 1991, he was featured in Perri "Pebbles" Reid's hit single "Always" from the album of the same name, along with Pebbles' cousin, R&B; singer, Cherrelle. The single made the R&B; Top 20 shortly after its release.
In 1993, Gill released another solo project, Provocative, which included the songs "Quiet Time to Play," "A Cute, Sweet, Love Addiction," and a moving gospel, "I Know Where I Stand." In 1996, Gill was reunited with New Edition, including Brown, as they recorded Home Again, an album noted for the singles "Hit Me Off" and "Still In Love". The title song, "Home Again," although not released as a single is one of the most impressive vocal performances recorded by the group to date.
In 1996, Gill also released Let's Get the Mood Right, which included the title song, "Love In an Elevator," and "Maybe" which is considered by many to be one of his greatest vocal performances ever. The following year, he collaborated with Gerald Levert and Keith Sweat to form the supergroup LSG (Levert/Sweat/Gill) which resulted in the multi platinum debut album, Levert-Sweat-Gill, and a follow-up album in 2003 entitled LSG2.
Gill, the only member of New Edition who is not from Boston, was raised in Washington DC where he attended Kimball Elementary, Sousa Junior High, and Duke Ellington School of the Arts. His career dictated that he complete his high school education through the services of a tutor. Gill had planned to attend college and pursue a degree in electrical engineering, but his career came first.
His latest recording, "You For Me (The Wedding Song)" from the Madea's Family Reunion soundtrack received strong reviews from music critics as well as the general public. In 2008, Gill, as a member of New Edition, was the recipient of the Golden Note Award at ASCAP's 21st Annual Rhythm & Soul Music Awards.
On September 27, 2008, he began touring with Ralph Tresvant and Bobby Brown in a new group named Heads of State.
With over 80 television and film appearances as a singer and actor, Gill earned much acclaim for his cameo role on the hit TV show, Family Matters (TV series) and recently thrilled audiences singing "You For Me" in the movie "Madea's Family Reunion."
In October 2004 Rub You The Right Way appeared in popular videogame , playing on R&B;, Soul radio station CSR 103.9. Gill most recently starred in the 2009 stage play "A Mother's Prayer", which also stars Robin Givens, Shirley Murdock and Jermaine Crawford. In July 2010 Notifi Records based out of St. Louis, MO signed Gill to a recording contract with new music due in 2011.

In 1989, the band broke up, but reformed under the name Django. Django began performing original material and Gill became the groups keyboardist and main vocalist. Throughout high school Gill performed in a number of groups as both a singer and an instrumentalist and even acted in a few musicals, receiving the lead role of Tevye in the Saratoga high school production of Fiddler on the Roof. In 1993, Django released a cassette of original music. That same year Gill moved with his band mates from Saratoga, CA to Isla Vista, CA where he became a student at UCSB.
At UCSB, Gill became a prominent figure in the university town's vibrant music culture, performing regularly with The UCSB Gospel Choir, The UCSB Jazz Ensemble and The UCSB Middle East Ensemble. in 1994, Django released a full-length CD and became a favorite band of the Isla Vista party scene.
In the winter of 1995, Django's drummer Matt West left the band and was replaced by David Brogan of Evil Farmer. In the summer of 1996 Django toured across the country, eventually basing themselves in Augusta, Georgia for the rest of that summer. While in Augusta they built up a local following and received the blessing of the Godfather of soul himself, James Brown. Mr. Brown encouraged the boys to finish school before embarking on a music career. Taking his advice they headed back to Isla Vista. Upon arriving home, Django officially disbanded. Gill continued to play music with Lebowitz and Adams, forming numerous other bands from the fall of 96 through the winter of 97, before emerging as the Animal Liberation Orchestra and the Free Range Horns in the spring of 98.
After graduating from UCSB with a degree in history, Gill began his career as a professional musician, working as an accompanist for UCSB's Modern Dance Department. Later that year he relocated to the San Francisco Bay Area and began accompanying modern dance classes there as well. He also continued to perform with a smaller version of the Animal Liberation Orchestra and traveled with the group back and forth from San Francisco to Santa Barbara.
In 2000, Zach moved to Marin county, and began teaching music at a private school in Fairfax, CA. He also began working as a musical director for a number of theater companies in the north bay area. In 2001, Gill began performing as a solo artist under the name Zach Gill and the Fabulous Wonder Bakery as well as performing weekly as part of a dueling piano show.
In 2002, Gill left Marin and moved back to Santa Barbara. From 2002 to 2005 he toured heavily around the United States with ALO.
In 2005, he joined forces with college pal Jack Johnson. ALO was signed to Jack's label, Brushfire records, and Zach was also invited to join Jack's band. Since joining the group, Zach has diversified the group's trademark sound with his multi-instrumental zest, vocals, and dancing skills and ALO has become an international touring act. Over the past decade Zach has performed at festivals and on television shows around the world, including Saturday night Live, Late night with Dave Letterman, the tonight show with Jay Leno, Bonoroo, Glastonbury, Live Earth and the 2008 United States Presidential inauguration ball.
Zach's music has been featured in the "Curious George" film and soundtrack alongside Johnson. He has also collaborated with Aimee Mann and Jerry Harrison (Talking Heads) on a composition, "At the Edge of the World" for the Paramount Pictures documentary An Arctic Tale.
In 2008 Gill released an eponymous debut solo project with Brushfire Records entitled "Zach Gill's Stuff". The album features guest appearances by Steve Adams from ALO, Tristan Prettyman, Merlo and Adam (his Jack Johnson bandmates). The first single from the album, Family, features Jack Johnson on drums and appeared in the movie "Baby Mama" with Amy Poehler, Tina Fey and Greg Kinnear.
In support of his 2008 album release, Gill toured nationally with singer-songwriter Mason Jennings and with fellow keyboardist Kyle Hollingsworth of the String Cheese Incident. In 2009 he was brought in by UCSB's Arts and Lecture to perform for alumni, faculty and the current student body.
In February 2010, Brushfire records released ALO's sixth studio album entitled Man of the World produced by ALO and Jack Johnson. Gill has been touring and recording with both Jack and ALO throughout 2010.

Gill arrived on campus in 1980 and saw limited action in mop-up duty as a freshman, which at the time was still relatively unusual, as freshmen had only been recently allowed under NCAA rules to participate at the varsity level.
Nebraska started the 1981 season poorly, losing two of its first three games and performing anemically on offense at times in all three. Gill had found himself third on the depth chart prior to the Huskers season opener, behind Mark Mauer and Nate Mason.
Down 3-0 to Auburn at halftime during the fourth game, with the season on the verge of slipping away, Osborne inserted Gill into the game. The Huskers pulled out a 17-3 victory, and Gill was given the starting job the following week. Behind Gill, the Huskers demolished Colorado 59-0, thus setting off an unbeaten run through the Big 8 conference, which Nebraska would win outright for the first time since 1971. However, during the season's penultimate game against Iowa State, Gill suffered what initially appeared to be an innocuous leg injury. Instead, doctors discovered nerve damage which sidelined him for the remainder of the 1981 season. Although the Huskers would beat Oklahoma without him, they were not able to overcome a stingy Clemson defense in the Orange Bowl, where a win may have given the Huskers a possible national championship.
Gill came back strong during 1982 and led the Huskers to a second consecutive outright Big 8 title and a 12-1 record overall, losing only a controversial game at eventual national champion Penn State in September. However, he suffered the first of many concussions in a game against Missouri which would ultimately shorten his playing career.
During his senior season, Turner would call the signals for one of the most prolific offenses in college football history, averaging 52 points and 401 rushing yards per game. Gill finished fourth in the voting for the 1983 Heisman Trophy which was won by teammate Mike Rozier. The Huskers came within a whisker of a national championship, falling to the University of Miami, just one point short following a failed two-point conversion attempt in the 1984 Orange Bowl.
Overall, Gill finished with a 28-2 record in his three years as a starter, winning three consecutive outright Big Eight championships with a perfect 20-0 mark in conference play. Despite this, he was unable to lead the Huskers to a national title, falling agonizingly short in each of his three seasons.
Because of the great turnaround that Gill orchestrated in only his second season at Buffalo, he was one of two leading candidates to replace Bill Callahan as head coach of the Nebraska Cornhuskers. However, Bo Pelini was hired as the new Nebraska head coach.
Gill also interviewed for the head coaching position at Auburn University, losing out to Iowa State head coach Gene Chizik, who had a 5-19 record. On December 15, former NBA superstar and Auburn player Charles Barkley, who had previously endorsed Gill for the position, criticized Auburn's passing over of Gill in favor of Chizik, saying "race was the No. 1 factor. You can say it's not about race, but you can't compare the two résumés and say [Chizik] deserved the job. Out of all the coaches they interviewed, Chizik probably had the worst résumé."
The following day, December 16, Buffalo announced that Gill had agreed to a contract extension and a raise, with his contract running through 2013 and making him one of the highest-paid coaches in the MAC.
On September 4, 2010, Gill lost his Kansas debut at home to FCS school North Dakota State 6-3. The following week, on September 11, 2010, Gill and the Jayhawks upset #15 Georgia Tech 28-25 followed by a loss @ Southern Mississippi the next week 31-16 on September 17, 2010.
