They are double skins which are slippery & keep the lungs moist. They
lubricate the lung exterior so the membranes can slide against each other
as the lungs expand & contract to reduce friction.
The windpipe.
We may breathe up to 50 times a minute & up to 2.5 litres of oxygen per
breath.
Pulmonary respiration is where oxygen moves in & out of the lungs, carbon
dioxide is breathed out & oxygen is moved into the blood stream.

Breathing oxygen into the lungs & removing carbon dioxide by breathing out.
Increased demand for oxygen by the working muscles.
To live, to break down food into energy for work.
Increased tidal volume, increased minute volume, increased depth of breathing & increased
number of breaths.
When the body is not getting enough oxygen to work so it works without oxygen until it is
available. This will occur during the first 3 minutes of exercise & as we reach maximal heart
rate. The oxygen debt is the extra oxygen we have to breathe in on top of what we would
normally to bring the body back to normal equilibrium.
The total amount of oxygen a person can accommodate.
A high vital capacity means good aerobic fitness whereas a low one means poor stamina as
we would get out of breath quickly & maximum heart rate would be reached more quickly as
oxygen demand can’t be met.
Vo2 maximum is also called vital capacity. A high VO2 maximum means good aerobic fitness
whereas a low one means poor stamina as we would get out of breath quickly & maximum
heart rate would be reached more quickly as oxygen demand can’t be met.
