Q

What is the function of the ALVEOLI?

A

where gaseous exchange takes place

16
Q

What is the function of the PLURAL MEMBRANES?

A

lubricates the movement of the lungs and prevents damage

17
Q

Via which process of the respiratory system do muscles get oxygen?

A

gaseous exchange

18
Q

What are the two parts of the breathing process?

A

oxygen passes from the alveoli into the blood by diffusion to be circulated around the body. Carbon dioxide is then removed from the blood by gaseous exchange so it can be breathed out.

19
Q

What are the 4 steps of the inspiration process?

A

(1) external INTERCOSTAL MUSCLES contract, raising an expanding the ribcage
(2) DIAPHRAGM contracts downwards
(3) lung volume increases
(4) air is inhaled

20
Q

What are the 4 steps of the expiration process?

A

(1) internal INTERCOSTAL contract, lowering the rib cage
(2) DIAPHRAGM relaxes and pushes up
(3) lung volume decreases
(4) air is exhaled
