respiratory system; definitions

Question 1

aerobic

Answer 1

relating to, involving, or requiring free oxygen

Question 2

cellular respiration

Answer 2

the use of oxygen to produce energy in body

Question 3

turbinates? what do they do?

Answer 3

thin bones that are suspended from the nasal chambers.
1) its thin membrane secretes moisture in air
2) its epithelial lining is supplied with capillaries to warm and
increase humidity in air

Question 4

respiratory system function?

Answer 4

supply oxygen to all the parts of your body.

Question 5

larynx?

Answer 5

house of the vocal cords

Question 6

trachea?

Answer 6

a flexible tube that is supported by semicircular cartilage ring/ known as windpipe

Question 7

alveoli?

Answer 7

a grape-like cluster of tiny sacs that each bronchiole end up with.

Question 8

How thick are the cell walls of the alveoli? Why?

Answer 8

One-cell thick, so gas exchange/diffusion to take place

Question 9

What prevents the trachea from collapsing?

Answer 9

the semicircular cartilage rings

Question 10

Pleura?

Answer 10

layers of tissue that is a flexible membrane that envelops the lungs while allowing them to expand and contracting during inhalation and expiration

Question 11

What is the respiratory pigment in humans? location?

Answer 11

hemoglobin, red blood cells

Question 12

What is the role of the diaphragm in breathing?

Answer 12

diaphragm is a thoracic cavity that helps move the lungs so it can expand and contract when we breath

Question 13

asthma

Answer 13

severe allergic reaction that causes the bronchioles to suddenly contract

Question 14

bronchitis

Answer 14

bronchial tubes become swollen

Question 15

emphysema + cause

Answer 15

lungs loose elasticity – caused by smoking

Question 16

pneumonia

Answer 16

when alveoli fill with fluid

Question 17

lung cancer + cause

Answer 17

tumors form on the lungs – caused by smoking

Question 18

breathing; inhalation

Answer 18

ribs are pulled up and down while diaphragm is pulled downwards
pressure in chest is reduced = forces air down passageways -> lungs =
forced to expand

Question 19

breathing; exhalation

Answer 19

diaphragm and rib muscles relax = ribs drop and chest cavity becomes smaller
pressure becomes greater= squeezing air out of lungs
