Question

question 4
eccrine sweat glands:
a serve as \anchors\ for the arrector pili muscles
b produce a secretion that protects the body from growth of bacteria
c aid in cooling the body
d are not involved in the homeostasis of body temperature
e produce a secretion that oils the hair and skin

Explanation:

Eccrine sweat glands are the most common type of sweat gland. They produce sweat, which when evaporated from the skin surface, cools the body.

• Option A: Arrector pili muscles are attached to hair follicles, not eccrine sweat glands.
• Option B: Sebaceous glands (not eccrine) produce sebum which has some antibacterial properties.
• Option C: Eccrine sweat glands secrete sweat. As sweat evaporates (a process that requires heat absorption), it cools the body.
• Option D: Eccrine sweat glands are involved in body temperature homeostasis (cooling function).
• Option E: Sebaceous glands produce the secretion that oils hair and skin.

Answer:

C. aid in cooling the body
