Magazi - magazi zamoyo zonse kufalitsidwa mu dongosolo la mwazi munali zakudya ndi mpweya. Zikomo kwa iye, pali thupi kagayidwe, minofu ndi ziwalo zonse zofunika pa moyo wao ndi kupereka mankhwala a kagayidwe. Amakhala ndi maselo otchedwa zinthu zinapangidwa plasma. maselo magazi kupanga pang'ono pa 40% buku magazi, enawo kuti nkhani mbali madzi magazi - plasma. Magazi m'thupi amagwira ntchito zambiri zofunika - zakudya, kupuma, kuteteza, kutentha kutengerapo.

Maselo onse magazi anawagawa m'magulu atatu waukulu wa maselo - maselo ofiira, maselo oyera ndi maselo othandiza magazi kuundana. Unyinji waukulu wa maselo amapanga maselo ofiira, limatchedwa maselo ofiira a magazi. Ndicho maselo ofiira kupereka magazi wofiira. Ntchito yaikulu ya erythrocyte - kugwira kuwombola mpweya, i.e. kunyamula mpweya maselo thupi ndi kusonkhanitsa kwa iwo mpweya. Kugwira mpweya kuwombola maselo ofiira muli wapadera mapuloteni hemoglobin. Mawonekedwe a maselo ofiira a magazi ali ngati concave mbali zonse za chimbale cha. Chifukwa mawonekedwe amenewa mosavuta kudutsa mu capillaries zazing'ono. Komanso, concave mbali zonse limachititsa kuwonjezera pamwamba maselo a magazi ndi ofunika kwambiri zoyendera bwino oxygen. maselo ofiira amenewa alibe mtima. The kutalika kwa moyo wa maselo amenewa ndi kwa masiku 90 mpaka 120, pa mlingo wa lita imodzi ya magazi a anthu, pafupifupi zili 5x10 12 madigiri, ndi akazi - 12 digiri 4,5h10 erythrocytes.

Mtundu wotsatira wa maselo a mwazi - maselo oyera, ndiye maselo oyera a magazi. Zimenezi zimathandiza kupanga kuchita mbali yofunika kwambiri kuteteza thupi ndi tizilombo toyambitsa matenda, mavairasi, ndi zinthu zosiyanasiyana yachilendo. Iwo kuyeretsa malo a matenda pambuyo chiwonongeko cha bakiteriya, umatulutsa mankhwala akupha, lomwe mbali yofunika kwambiri mu mapangidwe chitetezo chokwanira. maselo oyera amatuluka mu mafupa, ndulu, lymph mfundo. Izi maselo colorless ndi maso bwino anayamba. The zili maselo oyera mu magazi a munthu - 4-10h10 mu digiri chinayi pa lita imodzi ya magazi.

Potengera kupezeka za tirigu cytoplasm wa leukocytes ndi anawagawa granulocytes ndi agranulocytes. Ndi granulocytes ndi eosinophils, basophils ndi neutrophils, kuti agranulocytes - lymphocytes ndi monocytes. Aliyense wa mitundu ya maselo oyera ali specialization yake, ndi udindo kuchita mitundu yosiyanasiyana ya ntchito.

maselo magazi otchedwa othandiza magazi kuundana Ndipotu, ndi makombo a maselo zikuluzikulu - megakaryocytes. Othandiza ali amatchedwanso othandiza magazi kuundana. Ngati leukocytes, ali colorless, mulibe mtima, sapita ku mawonekedwe. Othandiza ndi loopsali kwambiri, mofulumira anawonongedwa mu kukonzekera atsopano. Othandiza mbali yofunika kwambiri mu ndondomeko yopindika, mapangidwe magazi kuundana ndi magazi asiye kutuluka. magazi kupatsidwa zinthu za m'mwazi achiyesa ranges ku madigiri 200 400h10 9 pa lita imodzi ya magazi.

maselo magazi anapanga mu ziwalo hematopoietic, ndiwo mafupa, lymph mfundo, ndulu. Mu thupi, pali mgwirizano inextricable anapanga zinthu ndi matupi imene amapangidwa ndi kuwonongedwa ndi unit lamulo la ndondomeko imeneyi.

The zili osiyanasiyana zinthu mawonekedwe - mtengo ndi zonse. Kuvutika kungakhale chizindikiro zofunika matenda osiyanasiyana. Chiwerengero cha mitundu yosiyanasiyana ya maselo magazi amasonyeza zambiri kusanthula ambiri a magazi leukocyte chilinganizo. kusanthula izi zikuphatikiza kuchuluka kwa magazi, mtundu index, erythrocyte sedimentation mlingo, maselo magazi. kusanthula tebulo amasonyeza zizindikiro zonse bwinobwino, ndi zomwe zotsatira angayerekezedwe.
