Choose the correct answer from the alternatives given.
Which of the following factors has little effect on blood flow in arteries?

• A. Skeletal muscle contraction
• B. Total cross-sectional area of vessels
• C. Blood pressure
• D. Heart beat

Answer 1

The correct option is A Skeletal muscle contraction

Skeletal muscle contraction affects blood flow in veins by increasing venous return to the heart. It has only little effect on arterial blood flow.

While arterial blood flow is mainly affected by activities of heart and neural and hormonal regulation.

So, the correct option is 'Skeletal muscle contraction'.
