Respiration
What is Respiration?
- Respiration refers to a series of chemical changes that take place in cells to release energy
- Respiration requires glucose and oxygen
- oxygen + glucose ~ carbon dioxide + water + energy
Respiratory system
- Takes air into your body and makes oxygen available to cells
- Takes in air and extracts oxygen from it
- Allows oxygen to pass into bloodstream, to be distributed to the cells for respiration
Nasal Cavity
- Air is warmed, moistened and cleaned
- Large dust particles are filtered by hairs in your nostrils
- Finer particles and some bacteria are trapped by a combination of sticky mucus and tiny hairs called cilia
Trachea
