Question 5

The liver is the primary producer of albumin. People with liver failure often show signs of extensive edema (tissue swelling).

Accepted Answer

A) Albumin, which is not normally released by the liver, causes capillaries to become leaky and release fluid into the surrounding tissues. 
B) Albumin, which is not normally released by the liver, causes an increase in blood pressure, which forces fluid into the tissues from the capillaries. 
C) The failing liver releases more albumin into the blood than normal. 
D) The failing liver releases less albumin into the blood than normal. 
A) Albumin, which is not normally released by the liver, causes capillaries to become leaky and release fluid into the surrounding tissues.
