Dziwani zambiri za mmene anthu matupi magazi ladzala ndi mpweya

Ziwalo zina magazi ladzala ndi mpweya? Yankho la funso limeneli sadziwa aliyense. Komabe, mwamtheradi aliyense amadziwa kuti kuchepa kwambiri mlingo wa mpweya ichi m'zotengera magazi ndi zinadzala ndi matenda osiyanasiyana a dongosolo kupuma ndi minofu mtima.

Ziwalo zina magazi ladzala ndi mpweya?

Kuti tiyankhe funso limeneli, choyamba tiyenera kukumbukira sukulu lathu thunthu "zokhudza zonse kufalitsidwa". Ndipotu, pa ndondomeko izi zimakhala thupi kukhala ladzala ndi zakudya zonse zofunika ndi oxygen. Ndipo izo zikuchitika mwa njira zotsatirazi: kuchokera ventricle kumanzere kwa minofu mtima , magazi wolumikizira pang'onopang'ono umayenda mwa mitsempha ziwalo zonse za thupi. Chifukwa cha bwalo lalikulu mu capillaries ndi mtundu wa kuwombola mpweya. M'mawu ena, mpweya kwa magazi akulowa zimakhala ndi carbon dioxide, m'malo mwake, amaperekedwa ku zimakhala mu magazi. The corpuscles wofiira ndi dzenje ndi mitsempha venous kulowa atrium chabwino, ndiyeno ventricle bwino.

Magazi mpweya machulukitsidwe amapezeka mu mapapo. Iye akudziwa za izo pafupifupi wophunzira. Mwa njira, amafotokozera izi kunditumiza ku onse ziwalo ndipo zimakhala, osati ndi mpope lathu lachibadwa - mtima, koma chifukwa ndi mapuloteni wapadera chonyamulira, zomwe zili corpuscles ofiira kapena otchedwa erythrocytes. Mu mankhwala otchedwa hemoglobin. Ndi iye amene limasonyeza mmene ndi mlingo wa magazi mpweya machulukitsidwe.

Norma mpweya magazi

Mu ena ziwalo magazi ladzala ndi mpweya, ife tinapeza. Komabe, nthawi yomweyo funso n'lakuti zimene ponseponse ake. Dziwani kuti boma yachibadwa pafupifupi onse hemoglobin chimamanga oxygen. Choncho yokha machulukitsidwe index ranges ku 96% mpaka 99%. Ngati mlingo yafupika ndipo zosakwana 95%, ndiye munthu anaona matenda aakulu mtima, dongosolo kupuma ndi minofu mtima. Komanso, mu magazi m'thupi aakulu (i.e., ndi msinkhu kwambiri wa hemoglobin ndi adatchithisira), wodwala mutazindikira ndi zinthu zina m'thupi (mwachitsanzo, kufooka, kuwonongeka msomali, khungu, etc.).

Ngati wodwala matenda a m'mapapo ndi mtima aakulu, zopatuka zikusonyeza ndi akuchuluka matendawa. Imeneyi, muyenera yomweyo funsani akatswiri. Ngati mpweya machulukitsidwe ndi liwiro ndi maziko a chibayo, chimfine, chimfine ndi matenda ena pachimake kupuma, ukuchitira umboni matenda m'malo lalikulu.

misinkhu monama otsika mpweya

Za matupi onse magazi ladzala ndi mpweya, tinakambirana pang'ono apamwamba. Tsopano tisaiwale kuti pamene kumupima mankhwala, pali zinthu zingapo kaŵirikaŵiri kungachititse munthu monyenga otsika misinkhu yachibadwa maselo a magazi. Choncho, kwa matenda lolondola ndi zofunika kwambiri amathera ochepa zasayansi miyezo mu mzere.
