Question

Choose the statement that best describes how the skeletal muscle pump works, Blood vessels in the skeletal muscle dilate during exercise to increasc blood flow. Increasing abdominal pressure and decreasing thoracic pressure during inhalation causes increased venous flow. Blood is pushed along the venous system as a result of the surrounding skeletal muscles pressing on veins. Smooth muscle cells surrounding the veins contract to increase venous pressure.

Answer 1

Step-by-step explanation:

The statement that best describes how the skeletal muscle pump works is "Blood is pushed along the venous system as a result of the surrounding skeletal muscles pressing on veins." During physical activity, the contraction of skeletal muscles surrounding the veins helps to compress the veins and propel blood forward. This is known as the skeletal muscle pump, which helps to enhance venous return and maintain adequate blood flow to the heart. The other statements are either incorrect or do not adequately describe the mechanism of the skeletal muscle pump.
