Could be more specific , it is the bilirubin in the bile that makes the "faeces" brown. Overall alright but being more accurate would help. Thanks !

Why do you say that PT measures factors 1, 2, 5, 7 9, 10? I thought that it was just the extrinsic pathway, so all of the above except for 9? I thought the vitamin K-related factors are impacted by warfarin but not necessarily to do with PT?
+Eric To Thanks for the question. The PT (INR) measures the extrinsic pathway - and is the one affected by warfarin (coumadin).  Heparin affects the PTT (intrinsic pathway).

The Hepatic Artery Comes from the Heart Into The Liver and The Portal Veins comes from the Gastrointestinal Tract, Spleen and The Pancreas which are all part of the Intestine . Both, The Hepatic Artery and The Portal Vein Supply Oxygen and Blood. Half Of The Blood From The Hepatic Artery Coming From The Lungs To The Heart To The Liver and Half From The Portal Veins . The Hepatic Veins which carries (Venous Blood) flows back to the Heart (Inferior Vena Cava).

hepatic artery comes from the heart. i never said it comes from the lungs . the hepatic artery does passes though the lungs where it receive it's oxygen content .
Saffron Maverick (3 years ago)
+InnOminandum X Hepatic artery DOES NOT come from Lungs......don't know which monkey anatomy book you read. Its a branch of common hepatic artery which in turn comes out from CT which comes from Abdominal Aorta & NO AORTA DOESNT COME FROM LUNGS EITHER.

@Matt Mason, he was talking about fat digestion, i.e, what happens in the intestines. The lipid molecules are not coming into contact with the liver itself, but with the bile salts that are released into the duodenum. You're right in that when absorbed, the fats enter the lymphatics rather than the blood, so are not part of the first pass metabolism. 
monica na (4 years ago)
Thank you so much, I listen to your lecture videos and they are logical and easily understood. Thank you again...
Matt Mason (4 years ago)
Around 3:30, the Dr. Seheult says that all the fatty acids absorbed by the intestines pass through the liver. I thought that lipids and their components (fatty acids) bypass the liver and enter circulation via the thoracic duct ... anyone have insight on this?

Is factor 9 part of the intrinsic pathway of coagulation and if so then PT would not indicate a deficiency of factor 9. However a deficiency in factor 5 would impact the PT.

Do you ever use albumin as a marker for protein-calorie malnutrition? I've read articles that indicate it's not a reliable tool to use for PCM? I still see hospitalists using it though. Thanks a lot for your excellent videos.
