Name the organ that is primarily involved in gas exchange
Lungs
What is bronchitis?
Inflamation of bronchioles [accept bronchi]
Name the small hollow spheres where gas exchange takes place.
Alveoli
This type of cellular respiration does not require oxygen
Anaerobic
This output is the main goal of cellular respiration

This gas is an input of cellular respiration
Oxygen
What is asthma?
Severe allergic reaction where bronchioles constrict making it hard to breathe
Give the two products of anaerobic respiration in yeast
Ethanol and carbon dioxide [Do not accept alcohol]
What is cellular respiration?
The process by which bonds of glucose are broken to release ATP for other life functions
What are the two waste products of cellular respiration?
Water and carbon dioxide
How do gases travel through the body
Blood
What is emphysema?
Air sacs deteriorate, gas exchange and. breathing difficult
Name the process by which oxygen moves from the airsacs to the blood.

Alveoli
What does the diaphragm do?
Affects breathing rate, inhale it goes up and exhale it goes down
