Respiratory System

Question 1

Alveoli

Answer 1

Have a thin lining and needs to be moist and clean for gaseous exchange to work. If they don’t work effectively it’ll affect our performance.

Question 2

What do the alveoli Do?

Oxygen in the alveoli diffused into the deoxygenated blood, haemoglobin carries the oxygen around the body. Carbon dioxide diffuses out of the blood into the alveoli, this is then breathed out.

Question 3

Immediate effects

Answer 3

Breathing becomes deeper, faster and stronger.

Oxygen debt occurs

Question 4

Long term effects

Answer 4

Improves efficiency of the lungs & increases lung capacity.

Increases tidal volume

Increases vital capacity

Increases amount of alveoli available for gaseous exchange

Question 5

Vital capacity

Answer 5

The largest amount of air that can be breathed in and out of the lungs by the most forceful inspiration and expiration

Question 6

Tidal volume

Answer 6

The amount of air breathed in and out of the lungs with each breath.
