generates heat

Answer 16

8. Muscular functions

Question 17

Provide examples of how the organ systems interact with each other

Answer 17

Your body is coordinating the action of entire muscle groups to enable you to move air into and out of your lungs, to push blood throughout your body, and to propel the food you have eaten through your digestive tract. Consciously, you contract your skeletal muscles to move the bones of your skeleton to get from one place to another
