Explanation:

Question 97

The internal iliac artery is known to supply blood to the pelvis, pelvic organs, and the gluteal region. The leg and foot are supplied by the external iliac (later femoral) artery, head and upper extremities by the subclavian and carotid arteries, and fingers by smaller arterial branches from the upper extremity arteries.

Hematocrit is the test or measurement that determines the volume percentage of red blood cells (erythrocytes) in whole blood. Spectrin is a protein in red blood cells, hematopoiesis is blood cell formation, and a hemocytometer is used to count blood cells (not specifically for volume percentage of RBCs).

The pericardium is the loose - fitting, inextensible sac that encloses the heart. The endocardium is the inner lining of the heart, the myocardium is the heart muscle, and there is no structure called exocardium related to the heart's covering.

Answer:

A. pelvis
