Question 5

Question 6

Trachea

The trachea, or windpipe, carries air to and from the lungs. It is made of C-shaped rings of rigid cartilage (to prevent it from collapsing).

Question 7

Bronchus and bronchioles.

Answer 7

We have two bronchi. Each bronchus carries air between the trachea and a lung. The two bronchi subdivide many times to form tiny tubes called bronchioles. Bronchioles carry air to and from the air-sacs, or alveoli.

Question 8

Alveoli

Answer 8

Each lung contains millions of tiny air-sacs called alveoli.
The function of each alveolus is gas exchange:
• Oxygen passes from the air in the alveolus into the blood vessels

Question 9
