Question

Quizplus · Accepted Answer

The integumentary system, which includes the skin, hair, nails, and exocrine glands, has several key functions. It provides resistance to infection (B) by serving as a physical barrier and through the activity of immune cells present in the skin. It allows for the sensation of environmental stimuli (C) through various types of sensory receptors that can detect touch, temperature, pain, and pressure. The system also plays a crucial role in thermoregulation (D), helping to maintain a stable internal temperature through mechanisms such as sweating and the dilation or constriction of blood vessels. Blood cell production (A) primarily occurs in the bone marrow, not the integumentary system. Vitamin E synthesis (E) is not a function of the integumentary system; instead, vitamin E is obtained through diet or supplements.
