Which of the following functions is associated with the spleen?
Producing coagulation factors
Destroying dying red blood cells
Producing leukocytes before birth
Storing glycogen
The Correct Answer is B
a: Producing coagulation factors - This function is associated more with the liver, which produces various clotting factors involved in the coagulation process.
b. Destroying dying red blood cells: The spleen is primarily involved in the destruction of old or damaged red blood cells. It acts as a reservoir for blood, where it filters out old or abnormal red blood cells, recycling their components and removing any potentially harmful substances.
c: Producing leukocytes before birth - Leukocytes (white blood cells) are primarily produced in the bone marrow, not the spleen.
d: Storing glycogen - Glycogen storage is mainly associated with the liver and muscles, not the spleen.

Correct Answer is B
Explanation
a. Left phrenic artery: The left phrenic artery arises from the abdominal aorta, not the ascending aorta. It supplies blood to the diaphragm.
b. Left coronary artery: The ascending aorta is the first section of the aorta, the major artery leaving the heart. It branches out to give rise to several arteries, including the left coronary artery, which supplies blood to the left side of the heart muscle.
c. Left subclavian artery: The left subclavian artery arises from the aortic arch, not directly from the ascending aorta. It supplies blood to the left arm and head.
d. Left intercostal artery: The intercostal arteries arise directly from the aorta, not specifically the ascending aorta. They supply blood to the muscles and tissues between the ribs.
