100

Gas exchange occurs in these tiny air sacs of the lungs.

Alveoli

100

This tube connects the throat to the lungs (generally called the windpipe).

Trachea

100

The leading preventable cause of lung disease worldwide.

Smoking
100

This index (often reported in weather apps) tells you how polluted the air is.

AQI (Air Quality Index)

100

Chronic respiratory disease that involves airway inflammation and episodes of broncho-constriction; causes wheezing, coughing, and shortness of breath

Asthma

200

Oxygen is transported in the blood primarily bound to this molecule.

Hemoglobin

200

These smaller branches of the bronchi regulate airflow and resistance.

Bronchioles

200

This type of prevention aims to stop lung disease before it starts (e.g., anti-smoking campaigns). [primary, secondary, tertiary]

Primary Prevention

200

This common air pollutant from vehicles can impair lung function.

Carbon monoxide (and/or nitrogen dioxide)

200

This infection can cause inflammation of the alveoli, sometimes causing the air sacs to fill with fluid or pus

Pneumonia

300

This process allows gases to move across the alveolar membrane based on concentration gradients.

Diffusion

300

This structure prevents food from entering the lungs during swallowing.

Epiglottis

300

This type of tobacco smoke exposure happens when someone breathes in smoke from another person's cigarette, cigar, or other tobacco product

Secondhand smoke exposure

300

Wearing this type of mask can help reduce inhalation of fine particulate matter during wildfires.

N95

300

Progressive scarring of the lung tissue, making it increasingly difficult for oxygen to cross from the alveoli into the bloodstream

Pulmonary Fibrosis

400

Located between the pharynx and trachea, this structure helps keep food out of the lower respiratory tract and contains the vocal cords

Larynx

400

During inhalation, contraction of the diaphragm causes the volume of the thoracic cavity to do this.

Increase

400

A substance capable of causing or contributing to the development of cancer is known by this term.

Carcinogen

400

Can make it harder to breathe and can irritate the lungs. It can come from things like cars, factories, and wildfires.

Air Pollution

400

Lining of the bronchial tubes becomes inflamed, often causing coughing and increased mucus production. It can be caused by infections or long-term exposure to irritants

Bronchitis

500

This thin, dome-shaped muscle is the primary muscle responsible for quiet breathing.

Diaphragm

500

When the volume of the lungs increases during inhalation, the pressure inside the lungs does what?

Decrease

500

Increasing tobacco taxes, restricting tobacco advertising, and creating smoke-free public spaces are examples of this type of public-health intervention.

Tobacco Control

500

Pollen levels often increase during certain seasons. For someone with asthma, exposure to high levels of pollen can trigger inflammation and make breathing symptoms worse

Allergen

500

This condition occurs when part of the lung collapses because air escapes into the space between the lung and chest wall
