Respiratory System Labeling

Label the Respiratory System:

1

State how air travels into the respiratory system. Starting with the nose.

Use must use the following organs: Bronchi, Alveoli, Trachea, Bronchioles, Nose

1

What is the function of the respiratory system?

1

Air enters the respiratory sytem through

3

Match the function/description to the organ.

Voicebox
Back of the throat
Air enters the respiratory system through this organ. The organ also filters and warms the air

Nose
Pharynx
Larynx

1

The main branches that branch off of the trachea

1

The small branches off of the bronchi that lead to the alveoli

1

The windpipe. Transports air from the nose/mouth to the lungs.

1

The tiny sacs where gas exchange occurs

1

The thin membrane that contracts and relaxes. This membrane changes the volume of the chest cavity forcing air in and out.

1

The act of breathing in is called

1

During inhalation (breathing in), what gas enters the body?

1

During exhalation (breathing out), what gas exits the body?

6

Match the description with the process of inhalation or exhalation

The chest cavity gets smaller
The diaphragm relaxes
Air is forced out of the lungs
The chest cavity expands
The diaphragm contracts
Air is forced into the lungs

Inhalation
Exhalation

1

As a person exercises, carbon dioxide levels in the bloodstream increase. This causes the brain to signal which of these systems to respond?

1

Where is the trachea located?

2

Look at the image. What gas moves into the alveoli? Explain why.

2

Look at the image. What gas moves out of the alveoli and into the blood? Explain why.
