1

What are the two additional muscles that help with inspiration during exercise

1. Sternocleidomastoid
2. Pectoralis minor

2

What are the two additional muscles that aid with expiration during exercise

1. Internal intercostals
2. Rectus abdominus

3

Is inspiration active or passive during exercise

Active

4

Is expiration active or passive during exercise

Active

5

During inspiration the diaphragm and external intercostals...

Contract more

6

During inspiration the sternocleidomastoid and pectoralis minor...

Contract

7

During inspiration the rib cage moves...

Up and out more

8

During inspiration the volume of the thoracic cavity...

Increases more

9

During inspiration the pressure inside the lungs...

Decreases more

10

During exercise a larger volume of air moves...

Into the lungs

11

As a result of the changes to inspiration and expiration, what happens to breathing

Breathing frequency increases

12

During expiration, the external intercostals and diaphragm...

Relax more

13

During expiration the rectus abdominus and internal intercostals...

Contract

14

During expiration the rib cage moves...

Down and in more

15

During expiration the volume of the thoracic cavity...

Decreases more

16

During expiration the pressure inside the lungs...

Increases more

17

During expiration a greater visual of air moves...

Out the lungs

18

What is the chemical control receptor

The chemoreceptors

19

What are the three neural control receptors

1. Thermoreceptors
2. Proprioceptors
3. Baroreceptors

20

Define the respiratory control centre (RCC)

The RCC is situated in the brain and controls breathing rate and depth

21

Define what the inspiratory centre does (IC)

Part of the RCC that controls inspiration

22

Define what the expiratory centre is (EC)

The EC is part of the RCC that controls expiration

23

Define what the phrenic nerve is

The phrenic nerve stimulates the diaphragm to contract

24

Define what the intercostal nerve does

The intercostal nerve stimulates the external intercostals to contract

25

Describe what the Hering-Breuer reflex is (3 parts)

1. Specialised baroreceptors between ribs that monitor lung stretch
2. When a threshold is reached it stimulates the EC to become active which stimulates the additional muscles to contract
3. Causes a faster and greater expiration
