Best simple explanation 1) Loud and clear voice 2) Simple language 3) Excellent drawings 4) Totally free You are really the best medical teacher on youtube
Someone give this guy a medal. Can draw, teach, and knows his medicine. Thumbs up! Also to guy below, he drew 1 artery for each organ just to summarize blood flow with those organs. They weren't the focus of the video.
Notes: Liver located under ribs. Has 4 lobes Bile duct comes from liver and galbladder Cystic duct comes from liver Blood supply: Aorta-> oxygenated blood to tissues-> hepatic artery, intestines is mesenteric Then blood will be deoxygenated and then blood will go to liver then portal vein which brings nutrients from other structures. Vein leaving liver is hepatic vein. Liver has oxygenated blood by right and left hepatic arteries. Vein leaving the liver towards the heart right, middle and left hepatic vein which connects to inferior venacava. Portal vein: brings in nutrients. Hepatic cells organization: Organized in hexagonal shape called lobular which have hepatic liver cells and there is central vein which connects to hepatic vein. Sinusoids connect with portal triads which are: 1.portal vein 2. Bile duct 3. Hepatic artery. All 3 connect to central vein and it’s how liver receives oxygen and nutrients Liver has special cells kapffer which are macrophages Cells produce bile and gives it to bile duct -> galbladder
These are very helpful! I am taking an online course and finding it hard to simply read my textbook. Love the videos as a supplement to my learning. Thanks for putting them together!
you said the sinusoids run from central vein to portal vein, while not incorrect, this gives the impression that the blood flows from central vein to portal vein where this is not the case. blood flow in the lobule is centripetal meaning the blood flows to the center of the lobule from the portal triad. It would also be useful to mention that the bile ducts are fed by microscopic ducts called canaliculi, these run beside hepatocytes collecting their waste products including bile, and the bile flows in a centrifugal fashion, from center of lobule out to portal triads. Beautiful drawings as always
I agree, when I listened to the presentation it gives the impression blood flow is from central vein to portal vein, when in fact is the opposite. It is important this is clear to understand the pathophysiology of many diseases. thanks for the presentation otherwise, really great.
I used to spend hours and hours to read a chapter :| and suddenly a hero name Armando came out with his Epic drawing turning the hours to minutes =) THANX m.Armando really thank you
Excellent video! Thank you so much. I actually remember these drawings during tests and it helps me a lot to understand the interconnections between the various syndromes.
I really thank u frm bottom of my heart Ur videos are so good that I understand easily every complicated things N thanks to the comments people who corrected ur mistake

maaaaaan this guy can draw!!!!!!
1. Cystic ducts comes from the gallbladder, not the liver.
2. Bile passes through the bile canaliculi , not through the sinusoids.
.....Anything.....else.....🤔🤔.....2019
yup
All I can say is a big THANKU!!! Not only u are a great teacher but an amazing artist too!!
I also think like it
Notes:
Liver located under ribs.

Bile duct comes from liver and galbladder
Cystic duct comes from liver
Blood supply:
Aorta-> oxygenated blood to tissues-> hepatic artery, intestines is mesenteric
Then blood will be deoxygenated and then blood will go to liver then portal vein which brings nutrients from other structures.
Vein leaving liver is hepatic vein.
Liver has oxygenated blood by right and left hepatic arteries. Vein leaving the liver towards the heart right, middle and left hepatic vein which connects to inferior venacava.
Portal vein: brings in nutrients.
Hepatic cells organization:
Organized in hexagonal shape called lobular which have hepatic liver cells and there is central vein which connects to hepatic vein. Sinusoids connect with portal triads which are: 1.portal vein 2. Bile duct 3. Hepatic artery. All 3 connect to central vein and it’s how liver receives oxygen and nutrients

Also the lymphatic flow is centrifugal
Thank you
Can u please tell me what is hepatic sinusoid please!
