Ovarian artery is a branch of –

**Core Concept**
The ovarian artery is a vital blood vessel that supplies oxygenated blood to the ovaries in females. It is one of the branches of the abdominal aorta that plays a crucial role in maintaining ovarian function.

**Why the Correct Answer is Right**
The ovarian artery arises from the abdominal aorta, specifically from the lower part of the aorta, below the renal arteries. This branching pattern is essential for the ovaries to receive a continuous supply of blood, especially during the reproductive years. The ovarian arteries then travel downward and medially to reach the ovaries, where they anastomose with the uterine arteries.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as the ovarian artery does not arise from the common iliac artery. The common iliac arteries are the main branches of the aorta that supply blood to the lower limbs and pelvic organs.

**Option B:** This option is incorrect as the ovarian artery does not arise from the renal artery. The renal arteries are the branches of the aorta that supply blood to the kidneys.

**Option D:** This option is incorrect as the ovarian artery does not arise from the external iliac artery. The external iliac arteries are the branches of the common iliac arteries that supply blood to the lower limbs.

**Clinical Pearl / High-Yield Fact**
The ovarian arteries are unique in that they are the only arteries that have a retroperitoneal course before reaching their respective organs. This anatomical feature is essential to remember during surgical procedures involving the ovaries or the abdominal aorta.

**Correct Answer: A. Abdominal aorta.**
