Maselo a anthu magazi ndi ntchito zawo

maselo magazi a anthu ndi imakhala ya madzi gawo kapena seramu. The madzi gawo - njira imene ili ndi kuchuluka kwa micro- ndi macroelements, mafuta, chakudya ndi mapuloteni. maselo magazi m'magulu zitatu zikuluzikulu, omwe ali zake mbali structural ndi ntchito. Tiyeni tikambirane zinthu zimenezi chimodzi kwambiri.

Erythrocytes, kapena maselo ofiira

maselo magazi Red - maselo m'malo lalikulu ndi khalidwe kwambiri mawonekedwe a litayamba biconcave. The corpuscles wofiira mulibe phata - pamalo ake ndi molekyulu wa hemoglobin. Hemoglobin - pawiri m'malo ovuta amene wapangidwa ndi mapuloteni gawo ndi atomu ya chitsulo akakhala. maselo ofiira amatuluka mu m'mafupa.

maselo ofiira ndi ntchito zambiri:

• kuwombola mpweya - izi ndi imodzi mwa ntchito zikuluzikulu za magazi. Amagwira ntchito ndondomeko izi zimachitika chabe hemoglobin. M'zotengera yaing'ono, magazi m'mapapo mwanga ndi mpweya, amene chikugwirizana ndi chitsulo hemoglobin. ubwenzi ndi kusintha, choncho oxygen amakhalabe mu maselo zimakhala kumene akufunika. Imodzi, imfa ya atomu imodzi mpweya chimamanga hemoglobin ndi carbon dioxide, amene anasamutsidwa ndi mapapo, ndipo linanena bungwe chilengedwe.
• Ndiponso, padziko maselo a magazi ndi yeniyeni polysaccharide mamolekyulu kapena antigens akanadziŵa RH ndi gulu magazi.

maselo magazi White, kapena leukocytes

maselo oyera - ndi ndithu gulu lalikulu la maselo osiyanasiyana amene Ntchito yaikulu ndi kuteteza thupi ndi matenda, poizoni ndi matupi yachilendo. Maselo amenewa ndi phata, akhoza kusintha mawonekedwe ake ndi kudutsa nsalu. Anapanga mu m'mafupa. maselo oyera akhoza kugawidwa mu mitundu ingapo:

• Neutrophils - gulu lalikulu la maselo oyera ndi kukhoza phagocytosis. cytoplasm awo lili pellets ambiri wodzazidwa michere ndi zinthu biologically yogwira. Pamene ozama mu thupi la mabakiteriya kapena mavairasi neutrophil chimatsatira analanda selo ena ndi adzautaya.
• Eosinophils - maselo ofiira a magazi, amene achite ntchito chitetezo ndi kuwononga zamoyo tizilombo ndi phagocytosis. Ntchito mu mucosa wa kapepalako kupuma, matumbo ndi dongosolo mkodzo.
• Basophils - kagulu ka maselo ang'onoang'ono chowulungika, amene kutenga nawo mbali pa chitukuko cha kutupa ndi anaphylactic mantha.
• Macrophages - maselo mwachangu kuwononga particles HIV ndi maselo mabakiteriya, koma ndi cytoplasmic kudzikundikira granules.
• Monocytes - yodziwika ndi ntchito yeniyeni, monga angathe kapena, kapena, Tikawonetsetsa ziletsa ndondomeko yotupa.
• Lymphocytes - maselo oyera a magazi ndi udindo ayankhe cha m'thupi. Mbali awo amatha kupanga kukana kuti tizilombo, amene ali kale pa kamodzi atagonjetsa mu magazi anthu.

Othandiza kapena thrombocytes

Othandiza - yaing'ono, sanali nyukiliya maselo a magazi a anthu chowulungika kapena mawonekedwe chonse. Pambuyo kutsegula mu akunja Kakhungu selo ndipamene ziyerekezo, ndi chifukwa kuti akufanana nyenyezi.

Othandiza ndi chiwerengero cha ntchito zofunika kwambiri. cholinga chawo chachikulu - mapangidwe otchedwa magazi aumirira. M'malo mwa anavulala anali woyamba kutenga maselo othandiza magazi kuundana, omwe Chiwabwerere michere timadzi kuyamba kukakamirana pamodzi, n'kupanga magazi aumirira. aumirira Izi mapulagi pabalapo mabasi magazi. Komanso, maselo amenewa magazi ali ndi udindo kukhulupirika ndi mtendere wa makoma mtima.

Tikhoza kunena kuti magazi - ndi m'malo ovuta mosalekeza mtundu wa polumikiza minofu anthu, lakonzedwa kukhala ndi moyo wabwinobwino.
