Which function of skin involves the release of waste products from the body?

Sensation
Excretion

The correct answer is: Sensation

The correct answer is Excretion. The function of excretion in the skin involves the elimination of waste products such as sweat, excess salts, and small amounts of urea. This process helps to regulate body temperature and maintain overall health. Sensation (choice A) refers to the skin's ability to perceive touch, pressure, temperature, and pain. Protection (choice C) involves the skin acting as a barrier against environmental factors and pathogens. Absorption (choice D) relates to the skin's ability to absorb certain substances such as medications or skincare products.
