Body temperature

The video explains how the human body maintains a constant internal temperature of 37°C, crucial for proper organ and system function. It highlights the role of the skin, the body's largest organ, in regulating temperature through mechanisms like sweating and goosebumps. Sweating helps cool the body by evaporating heat, while goosebumps trap warm air to heat the body. Accurate temperature measurement is possible only with a thermometer.

Why is it crucial for the human body to maintain a temperature of 37°C?

• To enhance muscle growth

• To ensure proper functioning of organs and systems

• To prevent dehydration

• To improve digestion

What tool is used to measure body temperature accurately?

• Barometer

• Thermometer

• Hygrometer

• Anemometer

How does sweating help in regulating body temperature?

• By increasing blood flow to the skin

• By releasing heat through evaporation

• By absorbing heat from the environment

• By reducing metabolic rate

What happens to the skin when the body is too cold?

• It becomes dry and flaky

• It forms goosebumps

• It starts sweating

• It changes color

What is the purpose of goosebumps in cold conditions?

• To trap warm air near the skin

• To reduce skin sensitivity

• To enhance skin elasticity

• To increase blood circulation
