100

The respiratory system's main job is to supply the body with this gas and remove carbon dioxide.

What is Oxygen (O2)?

100

Air enters the trachea after passing through this structure, commonly known as the "voice box."

What is the larynx?

100
This makes the alveoli very effcient at diffusion.

What is a high surface area?

100

This is the amount of air that always stays in your lungs, even after you blow out as hard as you can.

What is Residual Volume?

100

This is the primary treatment for a bacterial respiratory infection like bacterial Pneumonia.

What are antibiotics?

200

This describes the flow of molecules from a high concentration to a low concentration.

What is diffusion?

200

This is the physical pathway air takes, in order, from the trachea to the alveoli.

What are the bronchi and then the bronchioles?

200

These are the microscopic blood vessels that surround the alveoli to allow for gas exchange.

What are capillaries?

200

This device is used by doctors to measure the volume of air a person can inhale and exhale to create a lung volume graph.

What is a spirometer?

200

This is a serious illness characterized by an infection from a bacteria.

What is tuberculosis?

300

This is what happens when we complete inspiration.

What is air moves into the lungs from the atmosphere?
300

This specific phase of respiration involves the exchange of gases between the atmosphere and the blood in the lungs.

What is external respiration?

300

These are the products of cellular respiration.

What are ATP, water, and CO2?
300

On a spirometry graph, this is calculated by adding Tidal Volume, Inspiratory Reserve, and Expiratory Reserve.

What is Vital Capacity?

300

This genetic disease causes the body to produce abnormally thick, sticky mucus that clogs the lungs and leads to life-threatening infections.

What is Cystic Fibrosis?

400

This term refers to the entire process of moving air in and out of the lungs.

What is pulmonary ventilation?

400

To exhale, the diaphragm does this, which increases the pressure inside the chest.

What is relax?

400

This specific phase of respiration involves the exchange of gases between the body cells and the blood in the lungs.

What is internal respiration?

400

This is the extra volume of air you can breathe in above a normal, resting inhalation.

What is Inspiratory Reserve Volume (IRV)?

400

These are common symptoms often associated with sleep apnea.

What are insomnia, headaches, snoring, dry mouth, waking up throughout the night?
500

The way that the cardiovascular and respiratory system work together.

What is... the respiratory system pulls Ointo/pushes out of the lungs where it uses diffusion to get the gases in/out of the blood, while the cardiovascular system is able to get the gases throughout the body quickly using blood. The cardiovascular system will then use diffusion one O2 arrives at body cells.

500

This is the pathway that air takes as it enters our blood.

What is the nose -> nasal cavity ->pharynx -> epiglottis ->larynx --> trachea -> bronchi -> bronchioles -> alveoli -> blood

500

While most oxygen travels on hemoglobin, most carbon dioxide is actually transported in the blood as this ion.

What is bicarbonate (HCO3-)?

500

Many high-altitude populations have more red blood cells, but Tibetans are unique because of this reason.

What is... ESPA1 Gene. Their bodies do not produce excess red blood cells to increase oxygen levels, which would thicken blood. They compensate for the low levels of oxygen in other ways.

500

This is the clinical outcome for individuals with cystic fibrosis.

While there is no cure for CF, life expectancy has significantly increased. Usually patients are given antibiotics to prevent and fight infections, anti-inflammatories, and they practice airway clearing techniques. Even with these clinical interventions vital capacity can decrease over time as residual volume will increase.
