What is the term for the process of sweat secretion from the body?

The term for the process of sweat secretion from the body is perspiration. This physiological process involves the release of fluid, primarily composed of water and electrolytes, from sweat glands onto the skin's surface. Perspiration is an essential bodily function that helps regulate body temperature through the mechanism of cooling when the sweat evaporates from the skin.

In contrast, evaporation generally refers to the process where liquid turns into vapor, and while it plays a role in cooling when sweat evaporates, it does not specifically denote the act of the body secreting sweat. Hydration involves the process of maintaining adequate fluid levels in the body, which is related but does not specifically pinpoint the secretion of sweat. Transpiration commonly refers to the movement of water vapor from organisms, notably plants, or can also pertain to the moisture released from the skin, but in the context of this question, perspiration is the more precise term that specifically describes the secretion of sweat from the body.
