Answer 2

Hepatic Portal Circulation:

 Hepatic (hepato = liver) portal circulation detours venous blood from gastrointestinal organs (stomach and small intestine) through the liver before it returns to heart.

 After a meal, hepatic portal blood is rich in absorbed substances.

 Liver stores some and modifies others before they pass into the general circulation.

 For example, liver converts glucose into glycogen for storage hence maintains blood sugar homeostasis.

 It detoxifies harmful substances and destroys bacteria by phagocytosis.
