Which of the Following is True of the Celiac Trunk

Question

Which of the following is true of the celiac trunk?
A) It branches off the thoracic aorta.
B) It branches off the descending aorta.
C) It is part of the hepatic portal circulation.
D) It carries venous blood and drains into the portal vein.

Accepted Answer

The celiac trunk branches off the abdominal aorta, not the thoracic aorta. It does not carry venous blood, nor does it drain into the portal vein. While it supplies blood to the liver, stomach, and spleen, it is not part of the hepatic portal circulation. Therefore, B) It branches off the descending aorta is the correct answer.
