Question

Arterial blood supply to the uterus is derived from the uterine branch of what artery?

a) Internal iliac artery.
b) External iliac artery.
c) Common iliac artery.
d) Uterine artery.

Answer 1

The uterine artery, a branch of the internal iliac artery, provides the arterial blood supply to the uterus.

Step-by-step explanation:

The arterial blood supply to the uterus is derived from the uterine artery, which is a branch of the internal iliac artery. The internal iliac artery branches from the common iliac arteries and provides blood to various pelvic structures including the urinary bladder, walls of the pelvis, external genitalia, and in females, the uterus and vagina. In contrast, the external iliac artery is responsible for supplying blood to each of the lower limbs.

Answer 2

The arterial blood supply to the uterus is provided by the uterine branch of the a) internal iliac artery, which branches from the common iliac arteries and is distinct from the external iliac artery that serves the lower limbs.

Step-by-step explanation:

The arterial blood supply to the uterus is derived from the uterine branch of the internal iliac artery. The internal iliac artery is a branch from the common iliac arteries; it supplies blood to the urinary bladder, walls of the pelvis, external genitalia, and the medial portion of the femoral region.

In females, this artery also provides blood to the uterus and vagina, distinguishing it from the much larger external iliac artery, which supplies blood to each of the lower limbs.

Hence, the correct answer is Option A.
