Which of the following body systems does not rely on the autonomic nervous system to simulate involuntary events?

A. skeletal system
B. digestive system
C. circulatory system
D. respiratory system

A

The correct answer is A. skeletal system. The skeletal system is not controlled by the autonomic nervous system for involuntary events. Instead, it is under voluntary control by the somatic nervous system. The other options, B. digestive system, C. circulatory system, and D. respiratory system, all rely on the autonomic nervous system to regulate and control their involuntary functions.

To determine which of the body systems does not rely on the autonomic nervous system to stimulate involuntary events, let's first understand what the autonomic nervous system does. The autonomic nervous system controls involuntary processes in the body, such as heart rate, digestion, breathing, and blood circulation.

A. The skeletal system is not controlled by the autonomic nervous system. The skeletal system consists of bones, muscles, and joints, and its movements are mostly under voluntary control.

B. The digestive system relies heavily on the autonomic nervous system. It controls activities such as the movement of food through the digestive tract, secretion of digestive enzymes and acids, and absorption of nutrients.

C. The circulatory system is also regulated by the autonomic nervous system. It helps regulate heart rate, blood pressure, and blood vessel dilation or constriction.

D. The respiratory system is influenced by the autonomic nervous system. It controls processes such as breathing rate and depth.

Based on the above explanations, the correct answer is A. The skeletal system does not rely on the autonomic nervous system to stimulate involuntary events.
