Answer:

Inhalation

1. Inhalation is a part of breathing where the air is taken into the lungs by creating negative pressure by the contraction of respiratory muscles and diaphragm.

2. Inhalation is also called inspiration.

3. Inhalation is an active process as it involves the contraction of muscles.

4. The diaphragm contracts and flattens during inhalation causing it to move down.

Exhalation

1. Exhalation is a part of breathing where the air is drawn out of the lungs by the relaxation of respiratory muscles.

2. Exhalation is also called expiration.

3. Exhalation is a passive process as it involves the relaxation of muscles.

4. The diaphragm relaxes and becomes dome-shaped causing it to move up.

Answer:

Difference Between Inhalation and Exhalation

The table below shows the differences between inhalation and exhalation

Inhalation Exhalation

What it means

Intake of air into the lungs Expelling air out of the lungs

Type

Active process Passive process

Size of the chest in the process

Increases, expands Decreases, reduces

Diaphragm – role

Contracts, gets flattened by moving down Relaxes, moves up forming a dome-shape

Intercostal muscle – role

Relaxation of internal intercostal muscles and contraction of external intercostal muscles Contraction of the internal intercostal muscles and relaxation of external intercostal muscles

Lungs – volume

Rises to cause inflation Reduces causing deflation

Action it causes

Supply of oxygen-rich air to the blood Carbon dioxide is expelled out

Air composition

Inhaled air is a mix of oxygen and nitrogen Exhaled air is a mix of nitrogen and carbon dioxide

Air pressure

Decrease Increase

Effect of intercostal muscles

Ribcage moves upwards and outwards Ribcage moves downwards
