Question

!!!!NEED HELP ASAP!!!!Sal eats breakfast and then goes for a slow walk. What kinds of muscle are being used by Sal while participating in his

walk?
skeletal muscle, cardiac muscle, and smooth muscle
skeletal muscle only
O cardiac muscle only
O skeletal muscle and smooth muscle only

Answer 1

Sal uses skeletal muscles for movement, cardiac muscle in his heart to pump blood, and smooth muscles support involuntary processes during his walk.

Step-by-step explanation:

During Sal's slow walk, he is using skeletal muscles for voluntary movement of his limbs and cardiac muscle in his heart which pumps blood involuntarily through his circulatory system. While smooth muscles may not be primarily responsible for the action of walking, they are still active to some extent in processes like maintaining posture and controlling blood vessel constriction. Therefore, the correct answer is that Sal uses skeletal muscle, cardiac muscle, and smooth muscle while walking.
