In gasceous exchange where does the blood get carried to?
between the tissues and the lungs
3 of 25
What is the advantage of the Alveolus being covered in capillaries?
because they are so small gases can transfer through them.

What is Lung Volume?
the amount of air at different phases of the respiratory cycle
5 of 25
What is Vital Capacity?
is the amount of air that you can exhale after a maximum expiration.
6 of 25
What is Tidal Volume?
the amount of air breathed in and out during normal breathing
7 of 25
What is Residual Volume?
the air that remains in the lungs are a full expiration
8 of 25
What is Total Lung Volume?
the amount of air that your lungs can hold on one inspiration
9 of 25
What is Pulmonary Ventilation?
the process of air flowing into the lungs during inspiration and out of the lungs during expiration.
10 of 25
What happens to Tidal Volume when exercising?
Tidal volumes increase as the body is demanding more oxygen and the production of oxygen increases.

What is Neural Control?
neurones are activated in the Medualla Oblongata which is the bit of the brain that controls breathing, sends signals down the spine into the respiratory muscles to allow us then to breathe.

What is Alveoli?
There are about 300 million air sacs. They are surrounded by a dense network of capillaries that take part in gas exchange with the Alveoli
21 of 25
