Certified Nursing Assistant (CNA) Test 2025 – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

What does the muscular system do?

It produces insulin

It helps in oxygen transport

It assists in waste elimination

It produces heat

The muscular system plays a crucial role in producing heat through the process of muscle contraction. When muscles are engaged, they generate heat as a byproduct of energy expenditure. This is particularly important for maintaining body temperature, especially in response to cold environments. The heat produced by muscle activity contributes to overall thermoregulation in the body.

Other options do involve significant bodily functions but are not directly related to the muscular system. For example, insulin production is a function of the pancreas, while oxygen transport primarily involves the circulatory system, specifically the blood and its components. Waste elimination is largely handled by the excretory system, particularly the kidneys and urinary tract. Hence, the response regarding the muscular system's role in heat production is accurate and reflects its significance in overall body function.
