Please answer question number B)ii and iii

Dear Student

ii)  Blood vessel number 5 is Hepatic Portal Vein which contain the highest concentration of amino acids and glucose soon after a meal. It begins with capillaries in the digestive tract and ends with the hepatic sinusoids (capillaries) in the liver. 
The hepatic portal vein has blood that is deoxygenated. This is because oxygen left the blood in the capillaries of the digestive tract. The blood, now, contains nutrients, absorbed from the digestive tract. These absorbed materials leave the blood in the capillaries of the liver and are processed.

iii) Hepatic portal vein carries high amount of glucose and amino acid after a meal. Blood vessel number 5.
