In anatomy, a lobe is a clear anatomical division or extension of an organ (as seen for example in the brain, the lung or the kidney) that can be determined without the use of a microscope at the gross anatomy level. This is in contrast to the much smaller lobule, which is a clear division only visible under the microscope.
Interlobar ducts connect lobes and interlobular ducts connect lobules.
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.

This video will cover the structure of the liver.
This patient has struggled with infected cysts throughout his life. You can appreciate some scar tissue behind his ear and should always approach these posteriorly for cosmetic reasons. This healed fairly quickly.
Discussion of the hepatic lobule including histology.
A diagramatic revies of the liver lobules.
The Architecture of the Liver The liver is the largest organ in the body. Liver tissue is composed of a compact mass of multisided units, known as the hepatic lobules. Each lobule consists of a central vein, which acts as a tributary of the hepatic vein and conducts processed blood away from the lobule, surrounded by plates of liver cells. The liver receives blood from two sources, 80 percent, which carries digested food materials, arrives from the intestine via the portal vein and venules; the remaining twenty percent is oxygenated blood from the heart, which enters through the hepatic artery and arterioles. An exchange of materials takes place between the liver cells and the blood, which then passes into the central veins and returns to the general body circulation via the hepatic...

Subscribe to my Dermatology educational channel, Welcome to my channel! Hopefully this channel will show you a window into my world as a dermatologist. This cyst was infected for a month and was so irritated that the contents can be seen already starting to evacuate before any procedure was initiated. About 1/2 . This patient has an epidermoid cyst which has recently become inflamed and “infected”. I put “infected” in quotes, because technically this is not an infection: .
You know I wanna be a rockstar
So I can take you home with me
I wanna get up late
Go out on dates
And get in all the clubs for free
So when you see me standing here
And I see you standing there
And you watch while I'm up here
You know I'm the one
You know I wanna be sedated
With twenty-twenty-four hours to go
So get down on your knees
I'll teach you to please
When we hook up after the show
I dont know how to be complacent
Or ever have to mean a word I say
So open up your throat
Hope you don't choke
Welcome to a typical day
So when you see me standing here
And I see you standing there
And you watch while I'm up here
You know I'm the one
The one, the one, the one
Reality is warped for me when constantly
You tell me I'm so cool, To you
Just photo shoots and interviews
And killer food
What's a girl to do, With you
So I grew up to be a rockstar
Dont talk to me about legality
With your ass in the air
I really don't care
What your mama thinks of me
So now you see me standing here
And you're still standing there
And you watch while I'm up here
