Q

Where does blood go after being diffused in the lungs?

A

The capillaries

17
Q

Where does the Carbon Dioxide from the tissue fluid go to after being dissolved by cells?

A

It diffuses out of the blood into the air and out of the lungs, hence why we breathe out Carbon Dioxide

18
Q

A

Carbon Dioxide is excreted out of the lungs

19
Q

What is the process called when Oxygen is diffused into the blood and Carbon Dioxide out of the blood?

A

Gas exhange

20
Q

What is the process called when cells take Oxygen and glucose out of the tissue fluid and put Carbon Dioxide into the blood?

A

Respiration

21
Q
