anat respiration

Question 1

inhale muscles

Answer 1

sternocleidomastoid
elevates sternum

scalenes group
elevates upper rib

external intercostals
elevates ribs

diagrpahn
descend n elevates lower ribs

Question 2

exhale muscles

Answer 2

lung elastic recoil

internal intercostalis
pull ribs down

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

Question 3

funcion

Answer 3

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

Question 4

4 process of respiration

Answer 4

ventilation
external repsiration
internal respiration
cellular respiration

Question 5

ventilation

Answer 5

movement of air in/out of lung

Question 6

external respiration

Answer 6

exchange of gases btw lung/blood

Question 7

internal respiration

Answer 7

exchange of gases btw blood n body cells

Question 8

cellular respiration

Answer 8

oxygen ultilization and production of CO2 by body cells

Question 9

upper respiratory system

Answer 9

nose
nasal cavity
sinuses
pharynx

Question 10

lower respiratory system

Answer 10

larynx
trachea
bronchial tree
lungs

Question 11

function of membranes in nasal cavity

Answer 11

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

Question 12

function of cilia linings

Answer 12

push a thin layer of mucus/particles toward the pharynx

Question 13

conducting portion

Answer 13

transport air into/out of the lung

Question 14

respiration portion

Answer 14

allow gas exchange btw lung/blood

Question 15

lung sections

Answer 15

lobes: contains blood/lympatic vessels
lobules: terminal bronchi

fissure divide lobes

Question 16

purpose of sinuses

Answer 16

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

Question 17

cartilage larynx

Answer 17

the thyroid cartilage is more prominent in males bc sex hormones

Question 18

vocal cords

Answer 18

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

Question 19

pitch

Answer 19

controlled by changing tension on the cords

^tension=^pitch

Question 20

function of serous fluid

Answer 20

lubricates, reduces friction, allow sliding.

Question 21

pressure to volume relationship

Answer 21

^volume=! pressure

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

V1P1=V2P2

Question 22

hilus

Answer 22

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

Question 23

water

Answer 23

70%

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

Question 24

stimulis for breathing

Answer 24

H+ level directly

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

Question 25

mechanoreceptor in lung

Answer 25

tells you to stop breathing

Question 26

relax inhale

Answer 26

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

contract diaphragm and extern intercostalis

Question 27

iaphragm

Answer 27

touches parietal pleura

Question 28

relaxed exhale

Answer 28

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

Question 29

forceful inhale

Answer 29

muscle contract

Question 30

forced exhale

Answer 30

contract abdominal force compression abdominal internal intercostalis

medulla stop sending info to diapragm
