True or False, the lungs are made of muscle.

What is False?

100

These are the blood vessels that sit on alveoli

What are capillaries?

100

This muscle allows for air movement in the lungs.

What is the diaphragm?

100

This is why capillaries are effective at gas exchange.

What is they are very thin?

100

An increase in CO2 in the blood causes this pH change

What is decrease?

200

This is the key passageway that connects the mouth/nose to the rest of the respiratory system.

What is the trachea?

200

This is the cell responsible for carrying oxygen.

What are red blood cells (RBCs)?

200

When holding your breath, the pressure in the lungs and the atmosphere around you become ____

What is equal / the same?

200

During gas exchange, this gas moves from the blood into the alveoli

What is carbon dioxide?

200

This part of the brainstem is responsible for changing breathing rate to return pH to normal

What is the medulla?

300

These are the smaller branches that come of the bronci.

What are the bronchioles?

300

This is the key protein that binds to oxygen.

What is hemoglobin?

300

When breathing in, the diaphragm does this motion.

What is contract/move down?

300

True or false, CO2 attaches to the heme group of hemoglobin.

What is false?
300

These structures detect changes in pH.

What are chemoreceptors?

400

This is the key function of the larynx.

What is speaking / voice?

400

This is the number of oxygen molecules a single hemoglobin can bind to.

What is 4?

400

When breathing out, the diaphragm relaxes and volume and pressure of the lungs does this.

What is volume decreases and pressure increases?

400

Gasses like to move from a ____ to a _____ concentration

What is high to low?

400

This is the reason that carbon monoxide is so dangerous

What is CO has a higher affinity for hemoglobin?

500

This is the reason that alveoli are round, sac-like shapes.

What is to increase surface area for gas exchange?

500

These are the key structures inside hemoglobin that allow for binding

What is Iron (Fe) and a heme group?

500

Without a helmet in space, a person's lungs would collapse for this reason.

What is that outer space has much less pressure than our lungs, meaning the air from our lungs would be forced out?

500

This is the reason that athletes have trouble playing in Denver even though they breathe the same amount of air. (Don't just say there's less oxygen, WHY is this a problem)

What is the lower amount of oxygen creates less of a concentration gradient, meaning less oxygen flows into the bloodstream?

500

This is the VERY first thing in the feedback loop that would happen after a person would start running

What is a buildup of CO2 in the bloodstream?
