Question

which of the following is not a function of the integumentary system?
body temperature regulation
sensation
excretion of waste
delivery of oxygen

Explanation:

The integumentary system (skin, hair, nails, glands) has functions like body temperature regulation (e.g., sweating cools the body), sensation (nerve endings detect touch, pain etc.), and excretion of waste (e.g., small amounts of waste in sweat). The delivery of oxygen is a function of the circulatory system (blood transports oxygen) and respiratory system (lungs take in oxygen).

Answer:

delivery of oxygen
