Which action is associated with the relaxation of a circular muscle? The arm relaxes at the side The lips pucker for whistling The sphincter opening gets larger The leg bends at the knee

Answers

Answer 1

The action associated with the relaxation of a circular muscle is when the sphincter opening gets larger. The correct option is C.

Circular muscles, also known as sphincters, are found throughout the body and are responsible for controlling the opening and closing of various structures, such as blood vessels, digestive tract, and urinary system.

When a circular muscle relaxes, it allows for the widening or enlargement of the opening it surrounds.

For example, when the sphincter muscle in the digestive system relaxes, it opens up, allowing for the passage of food or waste material.

This relaxation and widening of the sphincter opening facilitate the movement of substances through the body. The correct option is C.
