• digestive system

The sheet of muscle, that separates the chest from the abdomen and helps the lungs to breathe:

• alveoli

• bronchial tubes

After air moves through the pharynx it continues down the _____, or windpipe, which has rings of cartilage to hold it open.

• trachea

• larynx

• epiglottis

The ____ are where the exchange of oxygen and carbon dioxide takes place in the lungs.

• trachea

• bronchial tubes

• bronchioles

• alveoli

The tubes that go from the trachea into the lungs:

• alveoli

• diaphragm

• epiglottis

• bronchial tubes

A flap of tissue that closes when we eat so food doesn't go down the trachea:

• larynx

• pharynx

• epiglottis

• oesophagus

The gas _______ is needed to stay alive.

The main function of the respiratory system is to:

• provide oxygen and remove carbon dioxide from the body

• bring oxygen to the body

• break down food and absorb nutrients

• remove oxygen from the body and deliver carbon dioxide

Within the lungs, the exchange of oxygen and carbon dioxide occurs between the ___ and the capillaries. 

• trachea 
• bronchi 
• alveoli
• diaphragm

What is the function of the bronchi?

• Transport air from nose to lungs

• Transport air from trachea to bronchioles

• Transport air from nose to alveoli
