Question

Divers instinctively prevent serious damage to arms and legs by pulling them in close to the body during a dive. Which two organ systems work together to accomplish this?
A. digestive and circulatory systems
B. muscular and digestive systems
C. nervous and muscular systems
D. circulatory and nervous systems

Answer 1

This reaction is similar to the one of yanking your hand back when you touch something burning hot. When this happens do you consciously think about pulling your hand back? The answer is no. Before the sense of pain reaches to your brain your spinal cord sends a message lightning fast to your muscles to move. Your body automatically does this to protect you from further harm, even before you feel the pain (although a split second after you will feel the pain and again be in control). This concept is the exact same in the situation of the question. This means that Nervous and muscular systems are working together to accomplish this.

Hope this helped!
