Mibvunzo yemuenzaniso nekukurukurirana kwemaitiro ekugadzirwa kweweti muitsvo
Kunzwisisa maitiro ekuumbwa kweweti kwakakosha kuti unzwisise nzira yekubvisa weti mumunhu. Itsvo, senhengo huru muhurongwa uhu, dzinosefa ropa, dzinobvisa tsvina, dzinochengetedza mvura ne electrolyte zvakaenzana, uye dzinogadzira mahormone akakosha. Chinyorwa chino chichakurukura zvakadzama maitiro ekuumbwa kweweti, pamwe chete nematambudziko emuenzaniso kuti zvikubatsire kunzwisisa chinhu ichi.
Maitiro Ekugadzirwa Kweweti Muitsvo
Kuumbwa kweweti muitsvo kune matanho matatu makuru: kusefa kweglomerular, kunyudzwazve kweropa, uye kuburitswa kwechubhu.
1. Kusefa kweGlomerular
Kusefa kunoitika mu glomerulus, muunganidzwa we capillaries dzeropa dzinowanikwa mu nephron. Izvi zvinoitika kana BP ichimanikidza mvura ne small solutes kubva muropa kuburikidza ne capillary walls kupinda mu Bowman's capsule, zvichigadzira glomerular filtrate. filterable solutes dzinosanganisira ma ions, amino acids, glucose, uye urea, nepo masero eropa nemapuroteni makuru zvichiramba zviri muropa.
2. Kudzoserwazve kweTubular
Kana yangoumbwa, glomerular filtrate inopinda mu proximal tubule. Pano, kudzoserwa kwemvura yakawanda nezvinhu zvakakosha muropa kunodzoserwa kuropa. Zvinhu zvakaita seglucose, sodium, potassium, uye bicarbonate ions zvinodzoserwa nenzira dzakasiyana kuburikidza ne active uye passive transport mechanisms.
3. Kubuda kweTubular
Maitiro ekupedzisira ndeekuburitsa zvinhu zvakaita sehydrogen ions, potassium, uye ammonia, pamwe nemishonga inofanira kuburitswa mumuviri, zvinotakurwa kubva muropa zvichienda mumvura iri muchubhu. Izvi zvinobatsira kuchengetedza acid-base balance yemuviri uye kubvisa chepfu muropa.
Mibvunzo Yekukurukurirana Yemuenzaniso
Kuti munzwisise zvakadzama, heano mimwe mienzaniso yemibvunzo nehurukuro dzayo maererano nemaitiro ekuumbwa kweweti.
Mubvunzo 1:
Tsanangura kuti BP yakakwira inogona kukanganisa sei maitiro ekusefa glomerular?
Kukurukurirana:
Kukwira kweropa kunogona kuwedzera kumanikidzwa kwehydrostatic mu glomerulus. Nekuda kweizvozvo, mvura yakawanda uye zvinonyungudutsa zvinogona kusundirwa muBowman's capsule, zvichiwedzera huwandu hwe glomerular filtrate. Zvisinei, kana kumanikidzwa kwakanyanya, kunogona kukuvadza madziro e capillary, kukanganisa mashandiro eitsvo kwenguva refu uye kubvumira zvinhu zvisingafanirwe kusefa, zvakaita seprotein, kupinda muweti - chirwere chinozivikanwa se proteinuria.
Mubvunzo 2:
Sei shuga iri muweti yevanhu vane chirwere cheshuga, kunyangwe ichiwanzotorwa zvachose?
Kukurukurirana:
Muvanhu vane chirwere cheshuga, huwandu hweshuga muropa hwakakwira zvekuti hunopfuura kugona kwakanyanya kudzoserwa kweshuga (renal threshold) mumatubules erenal. Kana huwandu hweshuga mufiltrate hwapfuura chiyero ichi, itsvo hadzikwanisi kudzoserwa glucose yese, saka imwe glucose yakawandisa inoburitswa muweti.
Mubvunzo 3:
Muviri unodzora sei kuenzana kwema potassium ions muropa kuburikidza nekuita kweitsvo?
Kukurukurirana:
Itsvo dzinochengetedza potassium ion balance kuburikidza nekuburitswa kwechubhu mu distal tubule uye mubutiro rinounganidza. Kana huwandu hwepotassium muropa hwakakwira, aldosterone inobatidzwa, izvo zvinowedzera kuburitswa kwepotassium muweti. Aldosterone inokurudzira sodium-potassium ATPase pump kuti iwedzere kuburitswa kwepotassium uye sodium reabsorption, zvichibatsira kuderedza huwandu hwepotassium muropa.
Mubvunzo 4:
Ndezvipi zvinhu zvinogona kukanganisa maitiro ekudzoreredzwa kwemvura muitsvo?
Kukurukurirana:
Maitiro ekunyudzwa kwemvura muitsvo anonyanya kukonzerwa nehomoni inorwisa diuretic (ADH). ADH inoita kuti madziro etubule apinde mumvura, zvichiita kuti mvura inyudzwe zvakare muropa. Zvimwe zvinhu zvinokanganisa zvinosanganisira osmolality yeropa, huwandu hweropa, uye kumanikidzwa kwe osmotic. Kurasikirwa neropa zvakanyanya kana kupera mvura mumuviri kunogona kuwedzera kuburitswa kweADH, nepo kuwanda kwemvura mumuviri kuchigona kuderedza kuburitswa kweADH.
Mhedziso
Maitiro ekuumbwa kweweti muenzaniso wakakwana wekuti muviri wedu unogadzirisa sei mamiriro emukati memuviri wedu. Kunzwisisa danho rega rega remaitiro aya kunotibvumira kunzwisisa basa rinokosha reitsvo muhutano nezvirwere. Nekushandisa mienzaniso yematambudziko nekukurukurirana, tinotarisira kusimbisa kunzwisisa kwedu nekugona kwedu kutarisana nematambudziko ekudzidza nezvenzira yekubuda kweweti.
Kana tiine mibvunzo yakakodzera yekudzidzira uye kunzwisisa kwakadzama kwepfungwa idzi, tinogona kushandisa ruzivo urwu zviri nyore mumamiriro ezvinhu ekurapa uye muhupenyu hwezuva nezuva. Kudzidza nezvemiviri yedu idanho rakakosha mukuvandudza hupenyu hwedu uye kuona kuti muviri wedu unoshanda zvakanaka.
