2.Describe what happens when Ventilation occurs in a human

# data[].attributes.body
To get the oxygen we need (breathing in, inspiration) and to remove the waste carbon dioxide we don't need(breathing out, expiration).

# data[].attributes.body
Movements of the ribs, rib muscles and diaphragm allow air into and out of the lungs. Take care - this is called ventilation.

When we breathe in, we inhale. When we breathe out, we exhale.
