Respiratory System

Question 1

Tidal Volume

Answer 1

The amount of air which enters the lung during normal inhalation at rest.

Question 2

Vital Capacity

Answer 2

The maximum amount of air someone can expire after maximum inhalation.

Question 3

Residual Volume

Answer 3

The amount of air that remains in the lungs.

Question 4

Minute Ventilation

Answer 4

The amount of air moved in one minute.

Breathing Rate x Tidal Volume

Question 5

Short Term Effects of Exercise

Answer 5

1) Breathing rate increases to take in more oxygen and exhale more carbon dioxide
2) Tidal Volume increases
3) EPOC (oxygen debt created if work done anaerobically)

Question 6

Long Term Effects of Exercise

Answer 6

1) Vital Capacity increases as you can breath in more air
2) Takes shorter time to pay off oxygen debt
3) Oxygen debt only created when heavier work is done

Question 7

When Inspiring

Answer 7

1) The diaphragm flattens and falls
2) Intercostal muscles contract towards the walls of the body
3) Ribs move outwards and upwards
4) Air Pressure inside the lungs decrease

This leads to a large area for oxygen to come as well as the need to even pressures.

Question 8

When Expiring

Answer 8

1) Diaphragm relaxes and pushes up
2) Intercostal muscles relax, falling inwards
3) Ribs move down and inwards
4) Air Pressure in the lungs

This leads to air being forced out of your lungs
