Ntchito magazi m'thupi la munthu

Pakuti asayansi anazunguzika ntchito magazi m'thupi la munthu. Chinsinsi chimene iwo akadali akuchepa ngati pang'ono kupatuka kapena kuphwanya zinthu zimenezi zimachititsa kuti imfa ya munthu mu nthawi yaifupi zotheka.

ntchito magazi m'thupi ndi yosiyanasiyana. Ntchito yaikulu ya magazi ndi kunyamula zinthu ndi kutengerapo oxygen. Kufalitsidwa kudzera ziwiya magazi amanyamula yambiri zakudya kwa thupi, makamaka mpweya, komwe kuli koyenera kuti "Mpweya Wake" aliyense wa maselo amoyo onse. Komanso, magazi amanyamula zakudya thupi lonse, amene kusungunuka mu thupi chifukwa cha chakudya. Anthu amenewa ndi ambiri ntchito zina magazi m'thupi zimadalira thanzi la tsiku ndi tsiku za boma lake la thanzi. Koma kodi tiyenera kuganizira kwambiri zimene timadya, zimene timamwa, ndi ena, kodi timapuma? Mwina si aliyense amene amapatsa yankho zabwino funso limeneli.

Ambiri a nthenda zathu amayamba chifukwa chakuti ife sititero nthawi kwambiri za moyo wathu. Choncho, tiyeni bwino kubwera kwa mfundo imeneyi ndi kuganizira zimene Kodi ntchito ya magazi ndi mmene bwanji thupi.

Pang'ono kuposa theka (pafupifupi 55%), nkhani mu magazi a madzi. madzimadzi izi momveka otchedwa plasma ndipo ali wotumbululuka chikasu. Otsala 45% ndi gawo wotanganidwa ndi magazi. Red maselo magazi amatchedwa maselo ofiira, maselo oyera - magazi maselo oyera izo. Pali mu zikuchokera magazi ndi maselo othandiza magazi kuundana, ndipo amatchedwa othandiza magazi kuundana. Mtundu wa magazi athu zimadalira pamaso pa hemoglobin. Hemoglobin otchedwa pigment mpweya ndi kukhala mtundu wofiira. Otuluka mapapo mumtima mwa mitsempha, ambiri hemoglobin ladzala ndi mpweya ndi kufalikira mu zimakhala za thupi, ali wolemera mtundu wofiira. magazi ndiye umabwerera kwa mtima kuchokera zimakhala thupi kudzera mu mitsempha, ndipo pano ali ndi mtundu mdima, chifukwa mu hemoglobin pafupifupi palibe mpweya. Pambuyo pake, magazi kumbuyo mu mapapo, akulinga chimodzimodzi mtundu wofiira, chifukwa izo ladzala ndi gawo lotsatira la mpweya, ndi ndondomeko akubwerezedwa kachiwiri.

Ndipo kodi ndi madzi?

Madzi a m'magazi - ndi amadzimadzi njira, imene onse ali particles zabwino ndi zoipa mlandu - ndi sodium, potassium chlorine, magnesium, ndi Mkhalidwe ndi kachulukidwe zikuchokera ayoni izi ngati zikuchokera madzi nyanja. Komanso alipo plasma wa zakudya za kagayidwe, mapuloteni, mavitamini, mahomoni. Iwo amapanga pafupifupi 10%, ndipo ena - ndi madzi.

Malinga ndi zofuna za thupi lake ndi chiwerengero cha atsopano magazi nthawi zonse kulamulidwa ndi malamulo ziwalo hemopoietic. Kodi ntchito ya magazi, ndipo moyenera, Gawo ake - maselo ofiira, oyera maselo othandiza magazi kuundana?

maselo ofiira ndi ofala zigawo zikuluzikulu kuti zimafala m'magazi. Hemoglobin ndi wandiweyani kwambiri mu maselo ofiira. Nchito erythrocytes ankaimbira kunyamula mpweya ziwiya magazi ndi mpweya. maselo ofiira ndi zigawo zikuluzikulu zofunika mu ndondomeko ya kupuma motero mayamwidwe mpweya wathu ku malo kunja kwa ife.

ndi maselo oyera a magazi ndi chiyani? Iwo ali ngati "zokometsera" wa thupi ku matenda osiyanasiyana amene angatithandize mu m'magazi. Nthawi kugwa maselo thupi kupanga zatsalira osafunika omwe leukocytes Komanso kukonzedwa. maselo oyera anawagawira mu monocytes, lymphocytes ndi granulocytes.

ntchito magazi m'thupi n'chofunika kwambiri. Izi makamaka kuonetsetsa mukachipinda zinthu zonse zofunika ndi kutulutsidwa kwa muli ndi kutsogolera kunja. amachita zonsezi malita asanu a madzimadzi, yomwe umoyo wathu.
