Respiratory System

Question 1

What do the lungs do

Answer 1

Allow movement of air in and out of body (ventilation) Air enters lungs during inspiration and leaves during expiration

Question 2

What do bronchi do

Answer 2

Air travels to each of the lungs via the bronchi - the term for both the left and right bronchus that take air to each of the lungs

Question 3

what do bronchioles do

Answer 3

the passage that the air travels down gets smaller as the bronchi subdivides. The smaller airways from the bronchi are called the bronchioles. They branch out throughout the lungs and carry air to the alveoli

Question 4

What do the alveolis do

Answer 4

They are tiny air sacs that are attached to the branches of the bronchioles throughout the lungs

Question 5

What does the diaphragm do during inspiration

Answer 5

the diaphragm contracts and flattens to make more space in the chest so the lungs can expand to pull in air

Question 6

what does the diaphragm do during expiration

Answer 6

the diaphragm relaxes and returns to a dome shape making the chest cavity smaller this helps to force air out of the lungs

Question 7

what happens to the diaphragm during exercise

Answer 7

due to the demand for additional oxygen by the working muscles the rate and depth of breathing increases this enables carbon dioxide to be removed at a faster rate

Question 8

Inspiration
Blood transportation
