The parts of the respiratory system

Two organs that remove oxygen from the air and pass it into your blood.

Passage connecting your throat and lungs.

Openings that pull air from outside your body into your respiratory system.

Small branches of the bronchial tubes that lead to the alveoli.

Tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place.

Where does gas exchange take place?

Tiny hairs that move in a wave-like motion to filter dust and other irritants out of your airways.

Hollow organ that allows you to talk and make sounds when air moves in and out.

Muscle that helps your lungs pull in air and push it out.

Tubes at the bottom of your windpipe that connect into each lung.

Tube that delivers air from your mouth and nose to the trachea (windpipe).

Blood vessels in the alveoli walls that move oxygen and carbon dioxide.
