What term relates to the glands in the skin that secrete perspiration?

1. Sulfa drug

2. Sweat gland

3. Symobiosis

4. Suspension

The correct answer is: Sweat gland

The term that specifically relates to the glands in the skin responsible for secreting perspiration is "sweat gland." Sweat glands are crucial components of the integumentary system, where they play a significant role in thermoregulation and moisture control in the body. These glands produce sweat, which is primarily composed of water, salts, and small amounts of other substances. When the body temperature rises, either due to environmental conditions or physical activity, sweat is released onto the surface of the skin. As it evaporates, it helps to cool the body down, maintaining a stable internal temperature. In contrast, other terms provided do not pertain to the process of perspiration or the glands involved; for instance, sulfa drugs are a type of antibiotic, symbiosis describes a close and often long-term biological interaction between two different biological species, and suspension refers to a mixture in which particles are dispersed but not dissolved in a fluid. Therefore, "sweat gland" is correctly identified as relating to the specific function of secretion of perspiration.
