Flashcards in Respiratory/smoking test Deck (41):
1

flap of cartilage that closes over the entrance to the larynx and trachea during the action of swallowing

Epiglottis

2

branches many times into smaller and smaller tubes; sends air to a lung

Bronchi

3

process of bringing in oxygenn and removing CO2 from the body

Respiration

4

Pulmonary

referring to lungs or the respiratory system

5

Lungs

exchange of CO2 for O2

6

Capillaries

thin-walled blood vessels where the exchange of O2 and CO2 occur; covers the alveoli

7

Alveoli

air sacs @ the end of bronchioles; a site for gas exchange

8

Cillia

tiny-hair like structures that filter dust particles from the air (located in the pharynx, trachea, and bronchi)

9

Mucus Membranes

soft tissue; lines the nose, mouth, and throat; when you breathe in the mucus membrane traps bacteria/pathogens

10

downward

When you breathe in, your diaphragm moves_____

11

larger

your chest cavity gets____when you breathe I

12

hiccups

tiny spasms of the diaphragm

13

mucus

slimy fluid made by mucus membranes that coats tis nasal passages, trachea & bronchi; traps particles from the air and adds moisture to air that's entering te lungs

14

Emphysema

air cannot move in and out of the lungs because the alveoli becomes blocked or lose their elasticity; can't breate normally, unable to get enoug oxygen to the body and worsens overtime

15

Asthma

narrows the trachea and causes airways to be cloggged with mucus

16

Bronchitis

buildup of mucus in the broncioles

17

Cronic Obstructive Pulmonary Disorder (COPD)

combo of chronic bronchitis and obstructive (blocked) emphysema; causes chronic coughing/difficulty breathing/frequent infections and eventually death; always linked with smoking

18

Diaphragm

sheet of smooth muscle (involuntary) that separates the chest cavity (holds lungs/heart) from the abdominal cavity (holds digestive system)

19

Pharynx

shared w/ digestive system from the back of the tongue to epiglottis (AKA throat; air flows into)

20

Larynx

base of the pharynx, aka voicebox, and where the vocal cords are located

21

Bronchioles

smaller tubes within the lungs, and @ end of each one: a cluster of thin-walled air sacs

22

Trachea

aka windpipe, has rings of cartilage around it

23

Nose/Nasal Cavity

where air enters through, warms and moistens the air so it does not dry out lung tissue, helps clean the air

24

Nicotine

an addictive drug found in tobacco, mild stimulant and muscle relaxant

25

Tar

sticky substance that contains many carcinogens and coats the inside of your airways

26

Carbon monoxide

a gas that blocks oxygen from getting into your bloodstream

27

addiction

the effects of nicotine on the brain lead to physical dependence and ____

28

snuff and chewing tobacco

leads to mouth sores and oral cancer

29

mainstream smoke

smoke inhaled and exhaled by the smoker

30
