ALVEOLI
|
The gas exchange takes place
|
|
|
CAPILLARIES
|
Mesh like thing that surrounds the alveoli
|
|
|
WHAT ARE THE PRIMARY FUNCTION OF THE RESPIRATORY SYSTEM?
|
1. Exchange O2 and CO2

|
|
RESPIRATION
|
Exchange of CO2 and O2 at the alveoli capillary level
|
|
|
VENTILATION
|
Air moving in and out of the lungs
