Itsvo basa: imperceptible basa

Tisinganyatsonzwisisi kuziva zvose mashandiro zvomukati zvose. Itsvo dziri zvakare kwete nyore sezvo ivo sokuti. Kunyange zvazvo chikuru kushanda neitsvo anozivikanwa. Vamwe vavo kuziva kunyange vanhu kure mushonga, pamwe nevamwe vadzidzi vari kuziviswa chete - ramangwana vanachiremba, nyanzvi dzezvinhu zvipenyu uye Veterinarians. Marongerwo uye kushanda itsvo akadzidza zvakadzama panguva dzakasiyana madhipatimendi. Isu ichanyanya pamusoro mabasa.

Kwete inonyatsozivikanwa kupfuura kushanda neitsvo ndiko kuramba kuramba dzose acidity ropa. Chokwadi, vakuru muviri zvakadaro kunzwisisa muitiro kwete chete itsvo chete. Uyewo chikamu basa weveta chiedza. Recent "Veda" iri chokuendesa ropa carbon dioxide. Asi itsvo reabsorb bicarbonate kubva weti uye secrete rehydrogen ions kupinda weti, saka kuderedza acidity ropa.

Uyewo, kwete zuva zvatinonzwa pamusoro renal basa, murau pamusoro yeplasma osmolality. Chinyararire, murima zvavari kuita kwakakomba basa chokuchengeta huwandu electrolytes muropa chakaipa. "The pakarepo foromani" iri dzakagadzirirwa iyi itsvo - the hypothalamus. Anokwanisa kuona kuwedzera electrolytes muropa uye kupa chiratidzo kuna pituitary shwanu. Somugumisiro vabudiswa antidiuretic kemikari, iro rinoita itsvo kuti weti yakawanda kuramba kwete kuunza mvura yakawanda iri weti. Nokudaro, electrolytes anonyorwa, uye mvura yakawanda. Somugumisiro, nhamba solute uye mvura - solvent zvakare anova muupenyu. Antidiuretic kemikari anokwanisa kuita zvimwe zvikamu nephron zvikuru permeable kuti mvura uye vakadzokera ropa kuitwa yakasvinwa.

Uyewo chinokosha mashandiro murau ropa parutivi itsvo kumanikidzwa. Hongu, vari kuita izvi uye kuti. Long-rokuti mutemo dzvinyiriro zviratidzi - neitsvo zvebhizimisi. Izvi basa rinokosha itsvo mumuviri womunhu achangobva rokufungwa zhinji cardiologists uyewo zvemwoyo chirwere - huru "muurayi" mudiki vanhu. Tichidzokera pamutemo renal ushande. In tsika zvinonzi akaziva nokuda kwetunhu renin, iyo inobata mamorekuru vangani yavaibvisa chloride huri muropa. The kwacho kunosanganisira mahormone akadai angiotensin uye aldosterone, namano avo chiito kunzwisisa chaizvo. Asi kuguma kudzorwa bhuku plasma, uye izvi zvinokanganisa kweropa. Ndokusaka "chinoumba" kunwa diuretics Zvisinei, hazvo panguva yakatarwa zvinodhaka potassium-nyasha, nekuti diuretics vasingawanzotauri kupatsanura pakati electrolytes, uye pasina zvakakwana potassium mwoyo kwakaipa.

Zvinoshamisawo chaizvo chepfungwa ndiwo kwetunhu kemikari erythropoietin. Kunyanya kufarira kemikari ichi, vatambi. Chokwadi ndechokuti nemhaka kemikari ichi kunowedzera okisijeni vatakuri - gemoglobinsoderzhaschih erythrocytes. Kana itsvo haisi okisijeni yakakwana - vanotanga kukurudzira masero matsvuku eropa. Naizvozvo, nguva dzose hamuna okisijeni pakurovedza zvakakwana, itsvo dzako vanotanga synthesize erythropoietin, uye pashure penguva yakati ndipo panouya mugumisiro yokurovedza - kuwedzera okisijeni vatakuri.

Uye kupedza kwataita pamusoro kushanda goho tsvina, Chokwadi, kukosha kushanda neitsvo. Tinoda mapuroteni upenyu, asi zvibereko zvayo muviri - the chepfu simba kupfuura. Aoma ngavabude Ura dzavo, asi mumwe mujenya anoenderera mberi itsvo mugove. Zviri ivo - kuchena vashandi, vashandi vanoramba, vanoita yedu kuipa womukati zvakatipoteredza zvakakodzera inoshanda. Ndicho Implementation kuti basa iri vari pasi mitemo nephron mano - dzichipfekeka chairema zvomukati wokuchena. Muitiro ropa kusunungurwa "tsvina" maviri-danho, kutanga yakasvinwa zvinenge zvose ipapo vakadzokera kunyika ropa. Uye padanho rimwe nerimwe pane zvakaoma pamutemo zvigadziriswe.

Kugara weti nemiedzo - shoma matanho atingatora kuona mamiriro neitsvo. No vanofanira kusateerera utano hwevashandi vaduku izvi.
