Flashcards in respiratory system Deck (24):
0

what happens when we breath

gas exchange
take in oxygen
release co2

1

External respiration

bring gas from outside into lungs

2

aerobic respiration

requires oxygen (plants and animals)

3

diaphragm

muscle that separates lungs from abdominal cavity

4

inhalation

diaphragm comes down and air rushes in

5

exhalation

diaphragm moves into arch and air is squeezed out of lungs

6

cilia

hairlike projections that prevent particles from entering lungs

7

what makes a good respiratory system

thin, moist, in contact with oxygen surrounding environment, in contact with transport system

8

nasal passages

filter, moistens and warms air hairs mucous membrane with cilia by capillaries

9

pharynx

throat

10

larynx

voice box

11

trachea

windpipe
kept open by rings of cartilages
ciliated mucous membrane

12

bronchi

two cartilage ringed tubes lined with ciliated cells

13

bronchioles

groups of tiny tubes with less and less cartilage

14

avioli

respiratory surfaces where gas is exchanged, have large surface area, 300 million in our lungs.

15

path of air

nasal cavity-> pharynx -> larynx-> trachea -> bronchi -> bronchioles -> avioli

16

what smoking can do

smoking = bad

17

lung cancer

tumors in lungs. mostly caused by carcinogens.

18

asthma

sever allergic reaction causing wheezing and breathing problems. bronchioles spasms

19

bronchitis

lining of bronchial tubes are irritated and swollen. passageways to alveoli may swell and fill with mucous

20

emphysema

lungs lose elasticity. permanent damage

21

pneumonia

alveoli are filled with fluid prevents exchange of gases

22

Internal respiration

gas exchange through lungs and bloodstream

23

Cellular respiration

atp production in mitochondria
