Cov nephron yog lub microscopic structural thiab functional unit ntawm lub raum. Nws yog tsim los ntawm lub raum corpuscle thiab lub raum tubule. Lub capsule thiab tubule txuas nrog thiab yog tsim los ntawm epithelial hlwb nrog lumen. Ib tus neeg laus noj qab haus huv muaj 0.8 txog 1.5 lab cov nephron hauv txhua lub raum.
Tsuas yog, nephron puas yog ib lub cell?
Lub luag haujlwm ntawm lub raum yog qhov nephron . Txhua tus tib neeg lub raum muaj kwv yees li 1.2 lab cov nephron , uas yog cov raj hollow tsim los ntawm a ib leeg txheej Cov nephron muaj ib lub raum corpuscle, proximal tubule, voj ntawm Henle, distal tubule, thiab sau duct system (Daim duab 2-2).
nephrons puas tuaj yeem tsim dua tshiab? “Yog tubules puas lawm tau yuav kho tab sis yog qhov kev puas tsuaj loj txaus nephron tej zaum yuav raug puas tsuaj. Hmoov tsis rau lub raum tuaj yeem tsim dua tshiab thiab rov zoo, tab sis lub raum tsis tuaj yeem tsim tshiab cov nephron , thiab hauv cov ntsiab lus ntawd, nws rov tsim dua tshiab yog txwv."
Ib qho ntxiv, nephron yog dab tsi thiab nws ua dab tsi?
Nephron , kev ua haujlwm ntawm lub raum, cov qauv uas ua rau cov zis hauv cov txheej txheem tshem tawm cov khoom pov tseg thiab cov khoom ntau dhau los ntawm cov ntshav. Qhov siab tshaj plaws cov nephron tshwm sim hauv cov neeg laus lub raum, lossis metanephros, ntawm thaj av vertebrates, xws li cov tsiaj reptiles, noog, thiab tsiaj txhu.
nephrons ua haujlwm li cas?
Cov nephron ua haujlwm dhau los ntawm ob theem txheej txheem: glomerulus lim koj cov ntshav, thiab tubule xa cov tshuaj xav tau rau koj cov ntshav thiab tshem tawm cov khib nyiab. Txhua nephron muaj glomerulus txhawm rau lim koj cov ntshav thiab tubular uas xa cov tshuaj xav tau rau koj cov ntshav thiab rub tawm cov khib nyiab ntxiv.

Puas yog phagocytes B lossis T cells?
Peb hom lymphocytes yog T cells, B cells, thiab cov hlwb uas tua neeg. T cells rhuav tshem cov kab mob tshwj xeeb thiab qhib B cells los tsim cov tshuaj tiv thaiv kab mob tshwj xeeb. Phagocytes tuaj yeem yog macrophages, neutrophils, monocytes, dendritic cells lossis mast cells
T cells thiab B cells ua haujlwm li cas?
Tom qab ntawd koj lub cev tuaj yeem tsim cov riam phom zoo tshaj plaws tiv thaiv cov neeg tawm tsam, uas tuaj yeem yog kab mob, kab mob lossis kab mob parasites. Lwm hom T-cells paub thiab tua cov kab mob uas muaj kab mob ncaj qha. Qee qhov pab B-cells ua cov tshuaj tiv thaiv kab mob, uas nthuav dav thiab khi rau antigens. T-cell (txiv kab ntxwv) tua kab mob qog noj ntshav (mauve)
Qhov sib txawv ntawm tus pab T cells thiab cytotoxic T cells yog dab tsi?
T hlwb yog li ntawd hu ua vim lawv feem ntau tsim nyob rau hauv lub thymus. Raws li cov npe hais tias pab T hlwb 'pab' lwm lub hlwb ntawm lub cev tiv thaiv kab mob, thaum cytotoxic T hlwb tua cov kab mob kis kab mob thiab qog. Tsis zoo li cov tshuaj tiv thaiv kab mob, TCR tsis tuaj yeem khi cov tshuaj tiv thaiv ncaj qha
Lub luag haujlwm ntawm T cells thiab B cells yog dab tsi?
T cells koom nrog hauv kev tiv thaiv kab mob ntawm tes, qhov B hlwb feem ntau yog lub luag haujlwm rau kev tiv thaiv kev dag ntxias (hais txog cov tshuaj tiv thaiv). Kev ua haujlwm ntawm T hlwb thiab B hlwb yog kom paub txog cov 'tsis yog tus kheej' antigens, thaum lub sijhawm ua haujlwm hu ua antigen nthuav qhia
Puas yog germaphobe puas yog kev puas siab puas ntsws?
Kev cai huv huv Germaphobes lub neej. Germaphobes muaj kev nyiam huv nrog kev huv thiab xav tias yuav tsum tau ntxuav ntau dhau, tab sis lawv tau raug kev txom nyem tiag tiag los ntawm kev tsis quav ntsej-yuam kev. Tib neeg feem ntau muaj ntau hom ntaub ntawv ntawm OCD
