Question

part b - lo 2, explain why we need sleep and what happens if we dont get enough sleep, including potential physical, emotional, social, and safety threats to health
when the ____ system becomes depressed from lack of sleep, an individual could be more susceptible to illnesses like the common cold or a cold sore.
∘ immune
∘ integumentary
∘ nervous
∘ cardiac

Explanation:

The immune system is responsible for defending the body against infections and illnesses. Lack of sleep can depress the immune system, making a person more likely to get sick, such as with the common cold or cold sores. The integumentary system (skin, hair, nails) is not primarily involved in fighting infections in this way. The nervous system deals with communication and control, not direct illness susceptibility from sleep loss. The cardiac system is related to the heart and circulation, not immune responses to illness from sleep deprivation.

Answer:

A. immune
