Y11 Respiration

What is respiration?

• the ability to detect or sense stimuli in the internal or external environment and to make appropriate responses

• the removal from organisms of the waste products of metabolism

• chemical reactions in cells that break down nutrient molecules and release energy for metabolism

• The process of getting air into (inhalation) and out (exhalation) of the lungs
