DanielleElmas [232]

Answer:

Option-E

Explanation:

Meta arteriole is a type of vessel present in the micro-circulatory pathway of the human body, which possesses characteristics of both the arteriole and the capillaries.

The structure of metarteriole usually connects the arteriole to the venules and they possess smooth muscle rings at the entrance of the vessel in the capillary and thus acts as a sphincter. This sphincter controls the flow of blood into the venules and capillaries.

The precapillary sphincters are usually closed but when the tissue needs the oxygen the sphincter opens and supplies the blood.

Thus, Option-E is correct.
