Qhov Tseem Ceeb Qhov txawv - Bowman's Capsule vs Glomerulus
Lub nephron yog lub luag haujlwm ntawm lub raum. Nws muaj lub raum corpuscle thiab lub raum tubule. Lub raum corpuscle yog cov khoom uas lim ntshav hauv nephron ntawm lub raum. Lub raum corpuscle yog tsim los ntawm ib tug tuft ntawm capillaries hu ua glomerulus thiab ib tug capsule uas yog collectively hu ua Bowman's capsule. Bowman's capsule yog ib qho membranous ob-walled capsule uas nyob ib puag ncig lub glomerulus ntawm nephron. Lub glomerulus muaj cov hlwb endothelial. Lawv yog ib pawg ntawm capillaries nyob rau ntawm qhov pib ntawm nephron. Raws li lawv qhov chaw nyob hauv nephron, ob hom nephrons tuaj yeem txheeb xyuas tau. Hauv cortical nephron, glomerulus nyob hauv lub raum cortex. Hauv juxtamedullary nephron, glomerulus nyob hauv lub raum medulla. Qhov sib txawv tseem ceeb ntawm Bowman's capsule thiab glomerulus yog, Bowman's capsule yog ob-walled capsule nyob ib ncig ntawm lub glomerulus ntawm nephron whereas glomerulus yog ib pawg me me ntawm cov ntshav capillaries hauv nephron.
Bowman's Capsule yog dab tsi?
Lub Bowman's capsule tseem hu ua glomerular capsule. Nws yog ib lub khob zoo li lub hnab. Thiab tuaj yeem pom nyob rau ntawm qhov pib ntawm tubular ib feem ntawm nephron ntawm lub raum mammalian. Lub glomerulus nyob ib puag ncig ntawm Bowman's capsule. Nws ua thawj kauj ruam ntawm cov ntshav pom kom tsim cov zis. Cov kua dej los ntawm cov ntshav hauv glomerulus yog sau los ntawm Bowman's capsule. Qhov glomerular filtrate no tau ua tiav nrog rau lwm qhov ntawm nephron thiaj li tsim cov zis. Lub siab hydrostatic yuam cov me me xws li dej, qabzib, amino acids thiab NaCl los ntawm cov ntshav hauv glomerular capsule rau hauv nephron. Cov txheej txheem tshwj xeeb no txhais tau tias yog ultrafiltration.
Daim duab 01: Tus Bowman's Capsule
Lub Bowman's capsule tau txheeb xyuas xyoo 1842 thawj zaug los ntawm tus kws tshawb fawb hu ua Sir William Bowman. Muaj ob tug ncej nyob sab nraum Bowman's capsule. Lub vascular ncej yog sab uas afferent thiab efferent arterioles nkag mus thiab tawm. Tus ncej tso zis yog sab qhov chaw uas lub raj txuas txuas tau pib. Los ntawm sab nraud mus rau sab hauv muaj ntau txheej hauv Bowman's capsule. Lawv muaj raws li nram no, Parietal txheej - Nws yog ib txheej ntawm squamous epithelium. Qhov no tsis koom nrog kev pom.
Bowman qhov chaw - Cov lim nkag mus rau txheej txheej no tom qab dhau los ntawm kev pom cov slits.
Visceral txheej - Nws tsuas yog nyob saum lub glomerular puag daim nyias nyias. Nws yog tsim los ntawm cov hlwb tshwj xeeb hu ua podocytes. Cov glomerular capillaries nyob hauv qab txheej visceral. Nws ua lub luag haujlwm tseem ceeb ntawm kev pom.
Kev lim dej thaiv - Nws yog tsim los ntawm fenestrated endothelium ntawm glomerular capillaries, fused basal lamina ntawm endothelial hlwb thiab podocytes, thiab pom cov slits ntawm podocytes. Cov txheej no tso cai rau dej, ions, thiab cov molecules me los ntawm cov ntshav mus rau hauv Bowman qhov chaw.
YGlomerulus yog dab tsi?
Lub glomerulus yog cov hlab ntshav ntawm cov hlab ntsha hauv cov qauv pob (Bowman's capsule) uas nquag koom nrog hauv cov ntshav pom kom tsim cov zis. Nws yog cov qauv tseem ceeb hauv lub raum corpuscle ntawm lub luag haujlwm ntawm lub raum hu ua "nephron." Lub glomerulus tseem koom nrog hauv ultrafiltration ntawm cov ntshav qhov twg dej, ions thiab me me molecules xws li qabzib lim los ntawm cov ntshav mus rau Bowman's capsule uas tau ua tiav los ntawm tubular ib feem ntawm nephron.
Daim duab 02: Lub Glomerulus
Cov qauv no tau muab npe tom qab tus kws kho mob Italian Marcello Malpighi (1628-1694). Nws yog ib zaug hu ua "Malpighian corpuscle." Nws lim ntshav plasma. Cov hlab ntsha ntawm cov ntshav capillaries yog kev txhawb nqa los ntawm intraglomerular mesangial hlwb. Cov ntshav yog lim los ntawm cov phab ntsa ntawm cov hlab ntsha ntawm cov hlab ntshav los ntawm cov glomerular barrier rau hauv lub khob zoo li lub hnab "Bowman's capsule." Cov filtrate (dej thiab lwm yam me me molecules) ces nkag mus rau lub raum tubule ntawm nephron.
Dab tsi yog qhov zoo sib xws ntawm Bowman's Capsule thiab Glomerulus?
- Ob leeg yog ib feem ntawm lub raum corpuscle.
- Ob leeg muaj nyob hauv "nephron" uas yog lub luag haujlwm ntawm lub raum.
- Ob leeg koom nrog cov txheej txheem ultrafiltration ntawm cov ntshav los tsim cov zis.
- Kev ua haujlwm ntawm ob lub qauv no tseem ceeb heev los tsim cov zis thiab tshem tawm cov khoom pov tseg ntawm lub cev.
Qhov txawv ntawm Bowman's Capsule thiab Glomerulus yog dab tsi?
