Practical 2 Flashcards
nasal cav fun
warms, filters, adn humidifies air
fun- smell (olfaction)
epiglottis
covers larynx (lungs) when swallowing
larynx
btw pharynx and trachea
voice box
air control to and from lower respir tract
thyroid cartilage
anter. attachment for voice ligaments
in larynx
lrg, flat, smooth part on front
cricoid cartilage
larynx
below thryoid cartilage
beginning arch of tracheal cartilage
arytenoid cartilage
post attach. vocal ligam
larynx
small
vocal folds- general fun
sound production
glottis
system inc. vocal cords and opening btw them
trachea
windpipe
c shaped hyaline cartil
larynx to lungs
carina
internal medial ridge splits trachea
tracheal cartilage
stripes
c shaped rings on trach
primary (main) bronchi
after bification of trach
R- wider and vertical
L- thinner and horizontal
secondary (lobar) bronchi
off primary bronchi
L- 2 bronchi
R- 3 bronchi
tertiary bronchi
most distal
branches off secondary bronchi
visceral pleura
forms outer layer lungs
pariteal pleura
lines pulmon cavity
connected internal walls thoracic cav
right lung
3 lobes super middle inferior connect to 2ndary bronchi
left lung
2 lobes
inferi
superior
connect to 2ndary bronchi
diaphragm
inhalation- diagra shrinks lung vol inc, pressure dec air allowed in exhalation- diagra expands lung vol dec, pressure inc= pushes air out
internal intercostal
line towards sternum and angle up
give structure to rib cage when exhaling
externa intercostal
angle down towards midline
give structure to rib cage when breathing
rectus abdominis fun
pulls sternum/ ribs down to meet expanding diaph. when exhaling to dec abdominal vol. and inc pressure
external oblique
compress abdomin
inc P
helps w/ defecation, vomiting and pushing
kidney
fun- urine formation
removes excess H2O, electr, and protein wastes from blood
ureter
off renal pelvis
transports urine from kidney to urinary bladder
urinary bladder
muscular sac on floor of pelvic cav.
fun- stores urine
urethra
drains urinary bladder + transp. semen
renal artery
oxygenated blood to kidney via afferent arterioles from abdominal aorta
renal vein
drains cortical radiate, arcuate, and interlobar veins
transports blood from kidney to infer. vena cava
flow of blood from renal artery to Glomerular
renal a, segmentary a, interlobar a, arcuate a, cortical radiate a, afferent arteriole
flow blood from Golmerular to inferior vena cava
glomerular, efferent arteriole, vasa recta + peritubular cap
vasa recta, cortical radiate v and arcutate v
peritubular cap to cortical radiate v, arcuate v, interlobar v, renal v, inferior vena cava
renal capscule
maintains shape and protects kidney
renal cortex
surrounds renal medulla
fun- filtr. blood + tubular reabsorb
renal medulla
urine to minor calyx
renal pelvis
urine major calyx to ureter
renal hilum
point exit for renal pelvis
superior to ureter
renal pyramid
seperates renal medulla into chunks
urine to minor calyx
fun- tubular reabsorb and secretion
renal column
divides medulla into pyramids
renal papilla
tip of renal pyramids (runs into minor calyx)
major calyx
urine from minor calyx to renal pelvis
segmental artery
blood from renal artery to interlobar a
interlobar artery
blood from segmen. a to acruate a
acurate artery
blood from interlobar a to cortical radiate a
arcuate veins
blood from venules off of vasa recta cap
drain to renal v
interlobar veins
drain to renal veins
detrusor muscle
3 layers sm musc
muscularis layer of urinary bladder
trigone
common site for urinary infections
opening b/ urecters and urethra on bladder floor
external urethral orfice
female
discharge of urine
prostatic urethra
male
location semen formation
urine transpor
membranous urethra
male
after prostatic u
transmits urine and semen
spongy urethra
extends from membranous urethra to end (urethral orfice)
transports urine and semen
internal urethral sphincter
closes urethral orfice
fun- maintains continence
external urethral sphincter
located in perineal pouch
glomerular capscule
“bowman’s”
encloses and protects glomerular
proximal convoluted tubule
inc. histology
from golmerular capsu
have microvilli
* lumen w/ sloughed brush border (cloudy appearance)
nephron loop
located mostly in the medulla
inclu. ascending and descending limbs
ascending limb
runs toward distal convoluted tubule
descending limb
runs down from glomerular to “U”
distal convoluted tubule
by juxtaglomerular complex
end of nephron
after ascending limb- re-enters coretex
collecting duct
recieve fluid from distal conv. tubule
