Taylor Swift

Taylor Alison Swift (born December 13, 1989) is an American singer-songwriter. Raised in Wyomissing, Pennsylvania, she moved to Nashville, Tennessee, at the age of 14 to pursue a career in country music. She signed with the independent label Big Machine Records and became the youngest songwriter ever signed by the Sony/ATV Music publishing house. The release of Swift's eponymous debut album in 2006 marked the start of her career as a country music singer. Her third single, "Our Song", made her the youngest person to single-handedly write and perform a number-one song on the Hot Country Songs chart.

Swift's second album, Fearless, was released in 2008. Buoyed by the pop crossover success of the singles "Love Story" and "You Belong with Me", Fearless became the best-selling album of 2009 in the United States. The album won four Grammy Awards, making Swift the youngest ever Album of the Year winner. Swift's third and fourth albums, 2010's Speak Now and 2012's Red, both sold more than one million copies within the first week of their U.S release. Speak Now's "Mean" won two Grammy Awards, while Red's singles "We Are Never Ever Getting Back Together" and "I Knew You Were Trouble" were successful worldwide. Swift's fifth album, the pop-focused 1989, was released in 2014 and sold more copies in its opening week than any album in the previous 12 years, making Swift the first and only act to have three albums sell more than one million copies in the opening release week. Its singles "Shake It Off", "Blank Space", and "Bad Blood" reached number one on the Billboard Hot 100. The album would go on to win three awards at the 2016 Grammys including Album of the Year making Swift the first and thus far only female artist to receive the award twice.

Blood

Blood is a bodily fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. When it reaches the lungs, gas exchange occurs when carbon dioxide is diffused out of the blood into the pulmonary alveoli and oxygen is diffused into the blood. This oxygenated blood is pumped to the left hand side of the heart in the pulmonary vein and enters the left atrium. From here it passes through the mitral valve, through the ventricle and taken all around the body by the aorta. Blood contains antibodies, nutrients, oxygen and much more to help the body work.

In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains dissipated proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets. The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is almost entirely transported extracellularly dissolved in plasma as bicarbonate ion.

Selena Gomez

Selena Marie Gomez (/səˈliːnə məˈriː ˈɡoʊmɛz/ sə-LEE-nə mə-REE GOH-mez;Spanish pronunciation: [seˈlena ˈɣomes]; born July 22, 1992) is an American singer and actress. Born and raised in Grand Prairie, Texas, she was first featured on the children's series Barney & Friends in the early 2000s. In 2007, Gomez came to prominence after being cast in the Disney Channel series Wizards of Waverly Place, in which she starred as the lead character, Alex Russo, until its conclusion in 2012. She formed the band Selena Gomez & the Scene after signing a recording contract with Hollywood Records in 2008; they released the studio albums Kiss & Tell (2009), A Year Without Rain (2010), and When the Sun Goes Down (2011) before beginning a hiatus in 2012.

Gomez entered the film industry with star billings in feature films including Ramona and Beezus (2010), Monte Carlo (2011), and Hotel Transylvania (2012). She embraced an increasingly mature public image with her star billing in the film Spring Breakers (2013) and her 2013 debut solo studio album, Stars Dance. The latter project debuted at number one on the US Billboard 200 and included the Billboard Hot 100 top-ten single "Come & Get It." Gomez was released from her recording contract with Hollywood Records following the completion of her compilation album For You (2014). She subsequently signed with Interscope Records to continue work on her sophomore studio album, Revival (2015). It debuted at number one in the US and featured the top-five singles "Good for You" and "Same Old Love" and the top-ten single "Hands to Myself."
