Answer to Question 1

Ans:
B

Feedback:

The level of some hormones is adjusted according to the amount of the substance that they control. In this case, insulin controls glucose levels and would increase in response to the increase in serum glucose that follows a meal. This differs from a negative feedback cycle in which a simple decrease in a hormone level stimulates production and/or release of that hormone. Positive feedback and hypothalamic-pituitary control are not evident in this situation.

Answer to Question 2

Ans:
A, B, D, E

Feedback:

Ascites, anorexia, bleeding tendencies due to neurological effects, and epigastric pain are common accompaniments to cirrhosis. Ascites occurs when the amount of fluid in the peritoneal cavity is increased and is a late-stage manifestation of cirrhosis and portal hypertension. Epigastric pain is caused by liver enlargement or peritonitis. The peritoneal fluid is seeded with bacteria from the blood or lymph or from passage of bacteria through the bowel wall. Because factors V, VII, IX, and X, prothrombin, and fibrinogen are synthesized by the liver, their decline in liver disease contributes to bleeding tendencies. Fever and obesity would be less likely to exist, as the pathology is not infectious in nature and malnutrition and impaired food metabolism are common.
