Diseases in Respiratory System
100

This organ is the main muscle responsible for breathing and is located just below the lungs.

Diaphragm

100

This gas is taken in during respiration and used by the body’s cells to produce energy.

Oxygen

100

Which lung has 3 lobes?

Right

100

This disease makes the airways swell and tighten, often triggered by dust, exercise, or allergies.

Asthma

200

These two spongy organs are where gas exchange takes place.

Lungs

200

Gas exchange primarily takes place in these tiny air sacs in the lungs.

Alveoli

200

This bony structure protects the lungs and helps them expand and contract during breathing.

Rib Cage

200

This viral infection attacks the nose, throat, and sometimes the lungs, causing fever, sore throat, and body aches.

Influenza

300

This tube, also called the windpipe, connects the larynx to the bronchi.

Trachea

300

This waste gas is produced by cells and exhaled from the lungs.

Carbon Dioxide

300

Tiny hairs in your nose and airways that trap dust and germs before they enter the lungs.

Cilia

300

This bacterial disease mainly attacks the alveoli in the lungs, causing coughing (sometimes with blood), chest pain, and difficulty breathing. It spreads through the air when an infected person coughs or sneezes.

Tuberculosis

400

These small air sacs in the lungs are where oxygen and carbon dioxide are exchanged with the blood.

Alveoli

400

This part of the blood carries most of the oxygen after it diffuses into the bloodstream.

Red blood cells/Hemoglobin

400

This sticky substance lines parts of the respiratory system and helps trap dust, microbes, and other particles.

Mucus

400

Infection that causes inflammation and too much mucus in these large tubes that carry air into the lungs.

Bronchi

500

This “voice box” sits at the top of the trachea and helps air pass into the lungs while also producing sound.   

Larynx

500

These tiny blood vessels are the place where oxygen enters the blood and carbon dioxide leaves it.

Capillaries

500

The other lung has fewer lobes because this organ takes up space in the chest.

Heart

500

Allergies, dust, or exercise can trigger this condition that narrows and swells the small airways, which happens in the...
