Flashcards
Respiratory System Function
Respiratory System Function
Primary function is to supply the blood with oxygen and remove carbon dioxide.
Breathing
Breathing
The process of inhaling oxygen and exhaling carbon dioxide.
Lungs
Lungs
Air enters here and oxygen is absorbed into the bloodstream.
Study Notes
- The respiratory system's main job is to get oxygen into the blood.
- It achieves this through the act of breathing.
- Breathing involves inhaling oxygen and exhaling carbon dioxide.
- Inhaled oxygen enters the lungs.
- The bloodstream then absorbs this oxygen.
