Question

Arcuate artery is found in
A. Kidney
B. Skin
C. Lungs
D. All of the above

Answer 1

At first, we must have some basic knowledge about the options mentioned in the question which can help us in finding the answer. The arcuate artery is also known as the arciform artery. They are named so because they are shaped in arcs because of the nature of the shape of the renal medulla.

Complete answer:
Arcuate arteries are the vessels of the renal circulation which are located at the border of the renal cortex and renal medulla. Thus, they are found in the kidney. The blood enters the kidney through the passage of a single renal artery. This then breaks down further into multiple interlobar arteries.
The arcuate arteries are branches of interlobar arteries formed when these arteries reach the boundary between cortex and medulla. The interlobar arteries split at right angles to form the arcuate arteries. Further, these arteries run between the cortex and medulla, parallel to the surface of the kidney.

So, the answer is option (A).

Additional information:
Arteries are muscular and elastic tubes that must transport blood under a high pressure exerted by the pumping action of the heart. Large arteries branch off from the aorta and give rise to smaller arteries or arterioles. The largest artery is the aorta which arises from the left ventricle of the heart.

Note: Arteries are defined as the muscular and elastic tubes responsible for transportation of blood through pressure exerted by the heart. Arcuate arteries arise from the renal interlobular arteries. Renal refers to the kidney and therefore, it has that arcuate artery is a sum in the kidney.
