Question 11

Hepatic arterial blood flow compensates for changes in which of the following?
A. Systemic arterial pressure
B. Portal venous blood flow
C. Kidney perfusion
D. Heart rate

Answer 11

Answer: B. Portal venous blood flow
Rationale: Hepatic arterial blood flow inversely relates to portal venous blood flow, meaning that when portal venous flow decreases, hepatic arterial flow increases, and vice versa. This is part of the hepatic arterial buffer response, which is essential for maintaining a consistent hepatic blood flow (HBF).

Question 12

Increased portal venous pressure can lead to the development of:
A. Renal stones
B. Pulmonary embolism
C. Esophageal and gastric varices
D. Pancreatic insufficiency

Answer 12

Answer: C. Esophageal and gastric varices
Rationale: When portal venous pressure rises, it can cause blood to back up into other areas of the systemic circulation. This often results in the development of esophageal and gastric varices, which are enlarged veins in the esophagus and stomach that pose a risk for bleeding.

Question 13

Autoregulation of hepatic blood flow ensures:
A. An increase in hepatic artery dilation with an increase in portal venous flow
B. A decrease in hepatic artery dilation with an increase in portal venous flow
C. Consistent hepatic arterial flow despite fluctuations in portal venous flow
D. An increase in portal venous flow with a decrease in hepatic arterial flow

Answer 13

Answer: C. Consistent hepatic arterial flow despite fluctuations in portal venous flow
Rationale: Hepatic blood flow is autoregulated, which means the liver can maintain a constant blood flow even when there are changes in portal venous flow. When portal flow is low, the hepatic artery dilates to compensate, ensuring the liver receives sufficient blood supply.
