Question

How perspiration maintains constant human body temperature??????????

Answer 1

Explanation:

Sweating: Your sweat glands release sweat, which cools your skin as it evaporates. This helps lower your internal temperature. Vasodilatation: The blood vessels under your skin get wider. This increases blood flow to your skin where it is cooler — away from your warm inner body.

Answer 2

Answer:

Thermoregulation is a process that allows your body to maintain its core internal temperature. All thermoregulation mechanisms are designed to return your body to homeostasis. This is a state of equilibrium.

If your body needs to cool down, these mechanisms include:

• Sweating/ prespiration: Your sweat glands release sweat, which cools your skin as it evaporates. This helps lower your internal temperature.

• Vasodilatation: The blood vessels under your skin get wider. This increases blood flow to your skin where it is cooler — away from your warm inner body. This lets your body release heat through heat radiation.

so at last,

Warm weather or exercise creates heat in the body. This causes the body to sweat (or perspire). The body feels cooler when the liquid sweat evaporates along with latent heat of the body. As the humidity increases, the rate of evaporation decreases.This determines the body's comfort level.
