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
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
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.
Nelly Hoffman Don't be a dick, and google it. Shanthan's point is that the cycstic duct continues at a T junction, branching down into the common bile duct and up into the common hepatic duct, not the liver itself. Making observations and reviewing information is a very good thing so instead of you being the smart arse, review and contribut where necessary.
Excellent video. One point: You consistently state the hepatic artery provides the oxygenated blood to the liver, while the portal vein provides nutrients. In fact, the portal vein provides more oxygen to the liver than the hepatic artery, due to higher volume.
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
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.
Careful: The bile duct from the portal triad does not connect to the sinusoids or the central vein [incorrectly stated as "...all these three [portal venule, portal arteriole, bile ductule] connect to the central vein" at 5m50, also incorrectly drawn at 6m40 with portal triad connecting with sinusoid]. The portal bile ductule connects to the bile canaliculi, which are completely separate from the sinusoids. The canaliculi drain bile made within the hepatocytes, and direct it to the portal bile ductules. Blood and bile do not mix in the sinusoids. The bile is travelling in the opposite direction to the blood, toward the portal areas. Within the liver, the bile remains in a completely distinct system from the blood, and drains into the duodenum.
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.

I'm not a med student, a mechanic and retired Veteran. Just trying to see what my sonogram is about and if I'm have issues due to my stent. Your drawings and explanations seem to help

Please listen up to all you medical students out there; this Gastroenterologist explains this perfectly. Well done Dr., thank you :)
Billa
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.
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
Your artistic explanation and a good audibility made the topic much easier to understand.
شكراً وبيض الله وجهك يا مدير. اخيراً صرت افهم وشرايك تجي تدرس عندنا
Im a visual learner and this has helped me a lot. Thank you so much!
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
Yes
Revising for my exams, this by far is the most clear and easy to understand lecture I have ever seen. Thank you💚💚

Also the lymphatic flow is centrifugal
Thank you
Can u please tell me what is hepatic sinusoid please!
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.
Great video as always. I always come back to this channel when I forgot my anatomy
Beyond words...especially the skill of drawing. The explanation too was explicit.
i love your videos. they help a bunch. While i always check other sources to further learn the material, your videos make perfect sense to me.
The cystic duct comes from the Gall bladder not the liver. @1:05
common hepatic duct comes from the liver, the cystic duct comes from the gall bladder. they come together to form the common bile duct.
I have spent months studying human anatomy and discovered an awesome website at Sebs Study Crammer (check it out on google)
Since you are that smart make us a video and show us challa
From both, actually. The gall bladder is attached to the liver so that's a minor mistake.
Nelly Hoffman Don't be a dick, and google it.
