Which process helps the skin in detoxifying the body?

1. Absorption

2. Insulation

3. Perspiration

4. Secretion

The correct answer is: Absorption

Absorption is the process that helps the skin in detoxifying the body. The skin is not just a protective barrier; it also absorbs substances from the environment. Through absorption, the skin can take in beneficial substances such as vitamins and minerals, but it can also help eliminate toxins and waste products from the body. This property of the skin contributes to the body's natural detoxification processes. Perspiration (option C) is a process by which the body regulates its temperature through the production of sweat, but it is not directly involved in detoxification. Insulation (option B) refers to the skin's role in helping regulate body temperature and maintain thermal balance rather than detoxification. Secretion (option D) refers to the production and release of substances such as sebum from the skin's glands and is not primarily related to detoxification.
