Question

"Water loss due to evaporation of fluid that has penetrated through the skin is termed ________ perspiration.

A sensible
B active
C insensible
D inactive
E latent"

Answer 1

Insensible perspiration is the term for water loss through evaporation from the skin, occurring passively and aiding in temperature regulation without requiring ATP. It accounts for a significant amount of water loss even at rest, and is influenced by environmental humidity. So, the correct answer is option c.

Step-by-step explanation:

Water loss due to evaporation of fluid that has penetrated through the skin is termed insensible perspiration. This process is not dependent on the body's energy in the form of ATP and occurs passively. Insensible perspiration is a continuous process that contributes to temperature regulation by releasing heat from the body as water evaporates.

This form of perspiration happens at rest and amounts to about 600 mL of water daily by evaporation from the skin. Moreover, another 400 mL of water vapor is lost in the air we exhale. High humidity affects the rate of evaporation, leading to a potential increase in body temperature if the sweat does not evaporate effectively.

So, the correct answer is option c.
