Resource summary
Breathing & Respertion
Resperation
Resperation refers to the series of chemical changes that takes place in cells to release energy.
Resperation System
Your respiratory system takes in air and extracts oxygen from it.
In the Cells
Respiration begins once the oxygen and glucose are together in the cells.
Breathing
The air in the alveoli is constantly replaced when you breathe. Breathing is involuntary.
Energy and oxygen
The amount of energy you consume in your food needs to balance the amount of energy you use.
Where the air goes
When you breathe in, some air may com through your mouth but most of it comes in through your nose.
Meriam
Gas exchange
The walls of the alveoli are only 1 cell thick and are surrounded by tiny blood vessels called capillaries.
