Answer 2

During inspiration diaphragm contracts and become flatten so the thoracic volume increases pressure decreases and inspiration occurs.
During expiration diaphragm relaxes and becomes dome shaped ,thoracic volume decreases and pressure increases and expiration occurs.
In an adult healthy humans respiration rate is 12 - 16 times per minute i.e approximately 5000ml per min
