Moyo umene umadutsa m'thupi lathu: Zimene muyenera kudziwa zokhudza magazi

Kodi munayamba mwadzifunsapo kuti madzi ofiira awa omwe amayenda m'thupi mwathu nthawi zonse, otchedwa magazi, amagwira ntchito yodabwitsa bwanji? Monga galimoto yonyamula katundu kupita mumzinda, magazi amanyamula zinthu zomwe timafunikira ku ziwalo zonse za thupi lathu ndikuchotsa zinthu zomwe sitifunikira. Ndi ofunikira pa miyoyo yathu. Lero, tiyeni tikambirane za madzi opatsa moyo awa.

Kodi magazi n’chiyani? N’chifukwa chiyani ndi ofunika kwambiri kwa ife?

Mwachidule, magazi ndi madzi ofunikira omwe amanyamula mpweya ndi zakudya kupita ku minofu ya thupi lathu, ndikuchotsa zinyalala kuchokera ku minofuyo. Mwa kuyankhula kwina, magazi amapitirira kuyenda m'thupi lathu lonse, kuthandiza kuti matupi athu akhale athanzi.

Nazi zina mwa ntchito zazikulu za magazi:

• Mpweya umene umalowa m'mapapu athu tikamapuma ndi zakudya zomwe timapeza kuchokera ku chakudya chomwe timadya zimapita ku selo lililonse laling'ono m'thupi lathu.
• Zimathandiza kunyamula zinyalala, monga carbon dioxide, zomwe zimapangidwa m'maselo kubwerera ku mapapo ndi impso ndikuzichotsa m'thupi.
• Amatiteteza ku matenda polimbana ndi tizilombo toyambitsa matenda tomwe timalowa m'thupi.
• Tikavulala , magazi amaundana kuti asiye kutuluka magazi.
• Imalamulira ndi kulinganiza kutentha kwa thupi ndi kuthamanga kwa magazi.

Pali zigawo zinayi zazikulu za magazi. Zigawo zinayizi zimagwira ntchito limodzi kuti zigwire ntchito zonsezi.

Kodi magazi amapezeka kuti? Kodi amapangidwa bwanji?

Magazi amayenda m'thupi lonse. Taganizirani mtima wathu ngati pompu yamadzi. Pampu iyi imatumiza magazi m'thupi lonse kudzera m'mitsempha yamagazi.

• Mitsempha yamagazi: Iyi ndi mitsempha yamagazi yomwe imanyamula magazi oyera komanso odzaza ndi mpweya kuchokera mumtima kupita ku thupi lonse.
• Mitsempha: Iyi ndi mitsempha yomwe imanyamula magazi omwe agwiritsidwa ntchito kale, opanda mpweya wabwino kuchokera ku minofu ya thupi kubwerera kumtima.
• Ma capillaries: Awa ndi machubu abwino kwambiri omwe amalumikiza mitsempha ndi mitsempha. Zakudya ndi mpweya zimasinthidwa pakati pa maselo kudzera m'mitsempha iyi.

Tsopano tiyeni tiwone komwe magazi amapangidwa. Fakitale yayikulu komwe magazi amapangidwa ili mkati mwa mafupa athu . Timatcha mafuta a m'mafupa . M'kati mwa mafuta a m'mafupa awa muli mtundu wapadera wa selo, womwe umatchedwa maselo oyambira. Maselo onse m'magazi athu, monga maselo ofiira a magazi, maselo oyera amagazi ndi ma platelet, amapangidwa kuchokera ku maselo oyambira awa. Akakhwima, amalumikizana ndi mitsempha yamagazi.

Tiyeni tsopano tiwone zomwe zili m'magazi.

Mwamuna wamkulu amakhala ndi malita 5 a magazi m'thupi lake. Mkazi amakhala ndi malita 4. Magazi amapanga pafupifupi 8% ya kulemera kwa thupi lathu. Ngati tiyang'ana kapangidwe ka magazi awa:

• Plasma: Izi zimapanga 55% yokha ya magazi.
• Maselo Ofiira a M'magazi: Awa amapanga pafupifupi 44% ya magazi.
• Maselo Oyera a M'magazi ndi Mapulateleti: Awiriwa pamodzi amapanga pang'ono, pafupifupi 1%.

Madzi a m'magazi

Ichi ndi madzi achikasu. Ndi madzi opitilira 90%. Kuphatikiza apo, mapuloteni ndi mchere zimasungunuka mmenemo. Ntchito yayikulu ya plasma ndikunyamula maselo ena amagazi ndi zinthu zofunika m'thupi lonse.

Maselo Ofiira a Magazi

Utoto wofiira umachokera ku puloteni yotchedwa hemoglobin . Hemoglobin ndi yomwe imanyamula mpweya m'thupi lonse. Nthawi ya moyo wa selo lofiira la magazi ndi pafupifupi masiku 120. Maselo akale akamafa, maselo atsopano amapangidwa mu fupa la mafupa.

Maselo Oyera a Magazi

Awa ndi asilikali a chitetezo chathu chamthupi . Ali ngati apolisi m'thupi lathu. Adani monga majeremusi oyambitsa matenda ndi maselo a khansa akabwera, maselo oyera amagazi amenewa amapita kukamenyana natiteteza. Pali mitundu ingapo ya izi.

Mapulateleti

Izi ndi zidutswa za maselo zomwe zimaoneka ngati zidutswa za mbale. Mukadula dzanja lanu, kutuluka magazi kumasiya pakapita kanthawi chifukwa cha ma platelet amenewa. Ndi omwe amabwera mwachangu ndikutseka bala ndikuyika 'plaster' pamenepo kuti magazi asiye kutuluka.

Kodi ndi matenda ati omwe amakhudza magazi?

Monga china chilichonse, magazi athu amatha kudwala matenda osiyanasiyana. Matendawa akhoza kugawidwa m'magulu awiri.

Khansa ya Magazi

Khansa ya m'magazi imachitika pamene maselo a m'magazi osazolowereka akuyamba kukula mofulumira chifukwa cha kusintha kwa majini omwe amapanga maselo a m'magazi.

• Khansa ya m'magazi
• Lymphoma
• Myeloma

Matenda Ena a Magazi

Izi ndi matenda omwe si a khansa pomwe maselo amagazi sangathe kugwira ntchito yawo bwino.

• Kuchepa kwa magazi: Ili ndiye vuto lofala kwambiri la magazi. Mwachidule, kuchepa kwa magazi m'thupi kumachitika pamene thupi lilibe maselo ofiira athanzi okwanira. Mwina munamvapo za kuchepa kwa magazi m'thupi chifukwa cha kusowa kwa ayoni . Ndi mtundu wofala kwambiri.
• Matenda Otsekereza Magazi: Awa ndi mavuto a ma platelet, kapena mapuloteni omwe amathandiza magazi kuundana.
• Matenda Otuluka Magazi: Imeneyi ndi vuto lomwe magazi sagwira ntchito bwino. Izi zingayambitse kutuluka magazi ambiri ngakhale chifukwa cha kuvulala pang'ono. Hemophilia ndi chitsanzo chodziwika bwino cha vutoli.

Kodi mungadziwe bwanji ngati pali vuto ndi magazi anu?

Njira yabwino yodziwira ngati pali vuto m'magazi anu ndi kuyezetsa magazi . Komabe, thupi lanu limakupatsirani zizindikiro zina.

Zizindikiro zodziwika bwino za vuto la magazi ndi izi:

• Kutopa ndi kutopa kwambiri: Ichi chingakhale chizindikiro chachikulu cha kuchepa kwa magazi m'thupi.
• Kudwala pafupipafupi: Maselo oyera a m'magazi akachepa, chitetezo cha mthupi chimafooka ndipo chiopsezo chodwala chimawonjezeka.
• Kutupa kosamveka bwino kapena kutuluka magazi kwambiri chifukwa cha kuvulala pang'ono: Ichi chikhoza kukhala chizindikiro cha kuchuluka kwa ma platelet m'magazi.

Chinthu china ndi ndulu yokulirapo . ndulu ndi chiwalo chomwe chimasefa ndikuyeretsa magazi athu. Pakakhala vuto ndi maselo amagazi, imayenera kugwira ntchito molimbika ndipo imatha kutupa.

Magazi athu ndi chuma chamtengo wapatali kwambiri. Ali ngati mafuta omwe amapatsa thupi lathu moyo. Chifukwa chake, ndikofunikira kwambiri kusamalira thanzi la magazi.
