- Affects of exercise on ventilation- Ventilation increases abruptly in the initial stages of exercise and is then followed by a more gradual increase.
- Type 1 pneumocytes- long and thin, provide a surface for the outside air and capillaries for oxygen and carbon dioxide to be exchanged. 
- Type 2 pneumocytes - short and round, they secrete surfactant lining the inside of alvioli , used to equal out the pressure in the aliviolus. ]]> 2021-01-07 23:12:48 UTC https://padlet.com/rhenson1/pwktnpd0qhomh1dm/wish/1065492379
