Through which structures does air pass to reach the lungs?

• Alveoli

• Bronchioles

• Capillaries

• Trachea

What is the primary function of the nodes in the lungs?

• To exchange gases

• To filter air

• To produce mucus

• To store oxygen

How is the bronchial tube structured?

• As a solid mass

• As a single tube

• As multiple branches

What do the branches of the bronchial tube resemble?

• Veins in a leaf

• Rivers in a delta

• Branches of a tree

• Roots of a plant

Which part of the respiratory system is responsible for splitting into branches?

• Diaphragm
