Which glands excrete perspiration and detoxify the body?

1. Sebaceous glands

2. Sudoriferous (sweat) glands

3. Salivary glands

4. Thyroid glands

The correct answer is: Sudoriferous (sweat) glands

Sudoriferous glands, commonly known as sweat glands, play a crucial role in the body’s ability to regulate temperature and excrete waste products. These glands are responsible for producing perspiration, which is primarily composed of water, salts, and small amounts of metabolic waste. When sweat is excreted onto the skin's surface, it evaporates, helping to cool the body down. Additionally, the process of sweating aids in detoxification by eliminating substances like urea and excess salts from the body, thus contributing to overall skin health. This is particularly important in maintaining the body's homeostasis and ensuring that it can effectively manage waste. In contrast, the other glands listed serve different functions. Sebaceous glands produce oil to lubricate and protect the skin, salivary glands are involved in digestion through the secretion of saliva, and thyroid glands regulate metabolism and hormonal balance but do not have a role in perspiration or detoxification.
