Gas exchange

Slide 13 - Slide

The walls of the lung capillaries and alveoli are extremely thin (1 cell layer).

The surface area (het oppervlakte)  of the alveoli is really big. This means gas exchange can happen at many places. 

Because of the thin walls and the big surface area, gas exchange can happen very fast!
(there are about 300-500 million alveoli's in your lungs)

Slide 14 - Slide

Gas exchange 
1) Oxygen comes from the air we inhale into the alveoli -> Oxygen goes from alveoli through the wall into the blood of the lung capillary -> blood brings Oxygen to all the cells in the body. 


2) Blood brings Carbon dioxide from cells to the lungs -> Carbon dioxide goes from blood through the walls into the alveoli -> We breath out the Carbon dioxide.

Check out the picture for all the parts!
The walls of the nasal cavity are covered with the nasal lining, which has mucus-producing cells (cells that produce mucus, slijm).
--> This is also called the mucous membrane.

The mucus moistens the air that you inhale. 

Under the nasal lining are a lot of small blood vessels that keep the nasal lining warm. This also warms up the inhaled air.
