respiratory system

Question 1

Short-term effects of exercise on the respiratory system

Answer 1

1. increase tidal volume
2. increased minute ventillation
3. increased frequency of breaths

Question 2

Effects of a cool down on the respiratory system

Answer 2

1. lower breathing rate
2. lower tidal volume
3. helps repay 02

Question 3

What are the mechanics of inspiraton

Answer 3

1. the external intercostals contract
2. the diaphragm contratcs and flattens
3. volume of the thoracic cavaity increases
4. pressure decreases
5. causes air to rush in

Question 4

What are the mechanics of expiration

Answer 4

1. the external intercostals relax
2. the diaphragm relaxes
3. volume of the thoracic cavaity decreases
4. pressure increases
5. air is forced out the lungs

Question 5

What muscles are used during inspiration when exercising

Answer 5

sternocleidomastoid,
pectoralis minor and scalenes contract

Question 6

What muscle is used during expiration when exercising

Answer 6

rectus abdominus contracts to pull to ribcage down forcibly

Question 7

what is known as the voice box

Answer 7

the layrnx

Question 8

Describe the changes in tidal volume during recovery after exercise

Answer 8

Tidal volume drops as soon as exercise finishes. however it remains higher then rest because oxygen is needed for recovery

Question 9

SHORT term effects on respiratory system

Answer 9

1. increased breathing depth
2. increased breathing rate
3. increased minute ventillation

Question 10

LONG term effects on respiratory system

Answer 10

1. incrased cappilaries around alveoli
2. inter costals grow
3. incrased diameter of capillaries

Question 11

describe the structure and function of the trachea

Answer 11

1. hollow pipe
2. allows a passasge of air to lungs

Question 12

effect of a cool down on respiratory

Answer 12

maintains elevated ventilation rate
