Respiratory+System+Notes+DB

Respiratory system notes Food→ Energy Cellular respiration- happens in the cells Food (glucose) + O2 (oxygen gas)→ release energy, the waste is O2 + H2O

Worst free radical almost ever Happens in all of your cells- trillions Might as well not eat if we don’t have oxygen

Fermentation- take food→ little energy Can’t live for long without energy

The respiratory system brings oxygen in. The respiratory system is ridding the body of H2O and Carbon Dioxide.

Nose: hair, mucus, sinuses

Pharynx- Trachea: wind pipe→ two bronchus → bronchioles→ alveoli Or Esophagus

Inhale- diaphragm contracts Exhale- diaphragm relaxes Breathing- change in pressure in the chest cavity- created by ribs and diaphragm

PUnctured cavity- can't breath
