Science Homeostasis

Front

What is homeostasis?

Back

Homeostasis is the ability of an organism to maintain a stable internal environment despite changes in external conditions.

Front

What are the key mechanisms involved in temperature regulation?

Back

Sweating, Shivering, Vasodilation, Vasoconstriction.

Front

What is cellular homeostasis?

Back

The ability of cells to maintain a stable internal environment despite external changes.

Front

What is a negative feedback loop?

Back

A mechanism in which the body senses a change and activates processes to reverse that change and restore homeostasis.

Front

How does the body maintain oxygen and carbon dioxide balance?

Back

Through the process of respiration.

Front

What is thermoregulation?

Back

The process by which the body regulates its temperature.

Front

What role does sweating play in temperature regulation?

Back

Sweating helps cool the body down by evaporating moisture from the skin.

Front

What is vasodilation?

Back

Vasodilation is the widening of blood vessels, which helps to increase blood flow and reduce body temperature.

Front

What is vasoconstriction?

Back

Vasoconstriction is the narrowing of blood vessels, which helps to conserve body heat.

Front

What happens during shivering?

Back

Shivering generates heat through muscle contractions to help raise body temperature.
