The more intense the exercise, the greater the concentration of CO2 in the blood

True

To combat this, your breathing rate increases to ensure CO2 can be breathed out

Anticipatory breathing rate increases

Capillary network surrounding the alveoli expands

This increases blood flow to the lungs and pulmonary diffusion

Breathing is controlled by neural and chemical factors

The respiratory centers of the brain send impulses to the respiratory muscles to control breathing frequency and tidal volume of each breath

The Sports Performer in Action

Respiratory System- immediate (short-term) responses

So, what do you know?

Define me!

Key Terms

When you start exercising what happens to your respiratory system?

Short term ( immediate) responses

Tidal volume : the amount of air you breathe in and out with each breath

Skeletal System

Respiratory System

Immediate Responses

1. Breathing rate increases

Muscular System

Pulmonary Ventilation: The amount of air we breathe in and out per minute

CV System

2.The amount of air we breathe in and out per minute (pulmonary ventilation) increases

Pulmonary Ventilation= Frequency X Tidal Volume

3.Tidal volume increases

at rest- Pulmonary Ventilation= 12x0.5 = 6 Litres

True or False

Neural and Chemical control

Breathing

Complete the following questions

Inspiration

( active process)

Expiration

( passive process)

1. Define Tidal Volume

2. Define Pulmonary Respiration

3. Identify 3 immediate (short-term) effects of the respiratory system

WHY?

How well did you do?

Increases in the depth and rate of breathing is detected by the stretch detectors of the lungs
