Flashcards in anat respiration Deck (30):
1

inhale muscles

sternocleidomastoid
elevates sternum

scalenes group
elevates upper rib

external intercostals
elevates ribs

diagrpahn
descend n elevates lower ribs

2

exhale muscles

lung elastic recoil

internal intercostalis
pull ribs down

abdominals
pull ribs down, compress abdominal organs pushing the diapragm up

3

funcion

filter incoming air n transport it into the body, air, and air sacs where gas exchange

4

4 process of respiration

ventilation
external repsiration
internal respiration
cellular respiration

5

ventilation

movement of air in/out of lung

6

external respiration

exchange of gases btw lung/blood

7

internal respiration

exchange of gases btw blood n body cells

8

cellular respiration

oxygen ultilization and production of CO2 by body cells

9

upper respiratory system

nose
nasal cavity
sinuses
pharynx

10

lower respiratory system

larynx
trachea
bronchial tree
lungs

11

function of membranes in nasal cavity

moisten air coming through and entraps dust/other entering w/the air

12

function of cilia linings

push a thin layer of mucus/particles toward the pharynx

13

conducting portion

transport air into/out of the lung

14

respiration portion

allow gas exchange btw lung/blood

15

lung sections

lobes: contains blood/lympatic vessels

lobules: terminal bronchi

fissure divide lobes

16

purpose of sinuses

open into nasal cavity
reduce weight
resonant chambers that effect quality of voice
produce mucus

17

cartilage larynx

the thyroid cartilage is more prominent in males bc sex hormones

18

vocal cords

true vocalchords have elastic fibers. produce sounds when air is forces btw upper n lower folds. vibration generates sound waves.

19

pitch

controlled by changing tension on the cords
^tension=^pitch

20

function of serous fluid

lubricates, reduces friction, allow sliding.

21

pressure to volume relationship

^volume=! pressure

if pressure decreases, outside air will be pused into the lungs

V1P1=V2P2

22

hilus

point at which the bronchi, pulmonary arteries and veins, lymphatic vessels, and nerves enter the lung.

23

water

70%

water and CO2 makes H2CO3 which breaks to H+ and HCO3-

24

stimulis for breathing

H+ level directly

chemoreceptor at aorta/caroitid artery minotor it. H+ is also monitored in CSF by medulla

25

mechanoreceptor in lung

tells you to stop breathing

26

relax inhale

medulla sends impulse to phrenic nerve to diaphragm=contract=^volume of lung

contract diaphragm and extern intercostalis

27

iaphragm

touches parietal pleura

28

relaxed exhale

relax diapragm,=^pressure
elastic recoil cuauses lung to compress.
relax of other muscles

29

forceful inhale

muscle contract

30

forced exhale

contract abdominal force compression abdominal internal intercostalis

medulla stop sending info to diapragm
