Qhov Tseem Ceeb Qhov txawv - Bowmans Capsule vs Malpighian Capsule
Cia peb xub pom cov qauv thiab kev ua haujlwm ntawm lub raum luv luv ua ntej saib qhov txawv ntawm Bowmans capsule thiab Malpighian capsule. Lub raum yog ib qho ntawm cov kabmob tseem ceeb tshaj plaws hauv tib neeg lub cev thiab feem ntau koom nrog hauv kev tshem tawm cov khoom pov tseg hauv cov khoom noj. Cov khoom siv excretory muaj xws li dej, urea, uric acid, creatinine, thiab ntsev ntawm sodium, calcium, magnesium, thiab poov tshuaj. Tsis tas li ntawd, lub raum kuj tseem pab tswj cov kua dej thiab electrolyte sib npaug ntawm lub cev, osmotic siab, khaws cov plasma cov khoom xws li qabzib, amino acids, thiab lwm yam., thiab tswj cov ntshav pH. Lub luag haujlwm thiab cov qauv ntawm lub raum yog nephron. Nephron yog tsim los ntawm ob feem ntau; (a) Malpighian capsule, uas suav nrog Bowman's capsule thiab lub raum glomerulus thiab (b) raum tubule uas suav nrog; Lub cev sib npaug ntawm cov tubules, Henle lub voj voog nrog qis qis thiab nce siab, cov tubule distal convoluted, thiab sau tubule. Qhov sib txawv tseem ceeb ntawm lawv yog, bowman's capsule yog lub khob zoo li qhov kawg ntawm lub raum tubule lossis nephron enclosing lub glomerulus, uas ua thawj kauj ruam hauv kev pom cov ntshav los tsim cov zis thiab ua ke nrog lub raum glomerulus, nws tsim Malpighian capsule.. Kab lus no tham txog qhov sib txawv ntawm Bowman's capsule thiab Malpighian capsule kom ntxaws.
Bowman's Capsule yog dab tsi?
Bowman's capsule yog ob-walled khob-zoo li tus qauv thiab tsim cov qhov muag tsis pom qhov kawg ntawm nephron. Nws yog lined los ntawm nyias semipermeable squamous epithelium. Cov kab noj hniav ntawm Bowman's capsule yog li 0.2 hli nyob rau hauv txoj kab uas hla thiab muaj qhov loj ntawm cov ntshav capillaries hu ua glomerulus. Bowman's capsule sau cov dej thiab lwm yam diffusible solutes los ntawm glomerulus los ntawm ultrafiltration.
Cov khoom sau npe yog 1. Glomerulus, 2. Efferent arteriole, 3. Bowman's capsule, 4. Proximal convoluted tubule, 5. Cortical collecting duct, 6. Distal convoluted tubule, 7. Loop of Henle, 8. Papillary duct, 9. Peritubular capillaries, 10. Arcuate leeg, 11. Arcuate artery, 12. Afferent arteriole, 13. Juxtaglomerular apparatus.
Malpighian Capsule yog dab tsi?
Lub Bowman's capsule thiab lub glomerulus sib sau ua ke Malpighian capsule lossis lub raum corpuscle. Glomerulus nyob rau hauv kev sib cuag nrog lub capsule. Cov ntshav ncig nyob rau hauv lub glomerulus yog cais los ntawm cov kab noj hniav ntawm Bowman lub capsule los ntawm ob tug heev nyias ib txheej cell tuab daim nyias nyias; lub endothelial txheej ntawm cov ntshav capillaries thiab epithelial txheej ntawm Bowman's capsule. Thaum cov ntshav nkag mus rau glomerulus los ntawm afferent arteriole, ntau cov ntshav xws li cov dej molecules thiab lwm cov kua dej molecules hauv cov ntshav plasma yog diffused rau hauv Bowman's capsule. Cov txheej txheem lim dej no ntawm kev pom cov ntshav uas tshwm sim hauv Malpighian capsule hu ua ultrafiltration.
Lub raum corpuscle nyob rau hauv lub cortex (txheej txheej) ntawm lub raum. Nyob rau saum toj, lub raum corpuscle muaj cov glomerulus. Cov ntshav lim tawm mus rau hauv lub raum tubule, ntawm txoj cai. Nyob rau sab laug, cov ntshav ntws los ntawm afferent arteriole (liab), nkag mus rau hauv lub raum corpuscle thiab pub lub glomerulus; ntshav ntws tawm ntawm efferent arteriole (xiav).
Qhov txawv ntawm Bowmans Capsule thiab Malpighian Capsule yog dab tsi?
Definition of Bowmans Capsule thiab Malpighian Capsule
Bowman's capsule: Nws yog ob lub phab ntsa sib npaug sib npaug uas ua rau cov zis tso zis thiab lub glomerulus, uas muaj txheej txheej sab hauv (visceral), ua raws li capsular epithelium, thiab txheej txheej (parietal) txheej, ua tiav, glomerular. epithelium.
Malpighian capsule: Nws yog daim nyias nyias nyias ntim cov poov xab thiab txuas ntxiv hla cov hlab ntsha nkag mus rau ntawm hilus.
yam ntxwv ntawm Bowmans capsule thiab Malpighian Capsule
qauv
Bowman's capsule: Bowman's capsule yog ib lub khob ob-phab ntsa zoo li tus qauv thiab ua rau qhov muag dig muag kawg ntawm nephron.
Malpighian capsule: Bowman's capsule thiab glomerulus sib sau ua ke Malpighian capsule.
Function
Bowman's capsule: Bowman's capsule sau cov dej thiab lwm yam diffusible solutes lim los ntawm glomerulus thiab dhau lub glomerular lim mus rau qhov sib thooj convoluted tubule.
Malpighian capsule: Lub ultrafiltration tshwm sim hauv Malpighian capsule.
