Question 3

Two Phases of Respiration:

Answer 3

Inspiration
Expiration

Question 4

–is the taking in of air or breathing in

Answer 4

Inspiration

Question 5

– is the breathing out or the expelling air from the lungs.

Answer 5

Expiration

Question 6

the intercostal contract to elevate the ribs and at the same time, the diaphragm contracts and is displaced downwards, thus, increases in size of the chest cavity.

Answer 6

INSPIRATION

Question 7

Air then passes out from the lungs to equalize the pressure

Answer 7

EXPIRATION.
