Thupi lathu limadutsa mitsempha ya 90,000 km yomwe imanyamula pafupifupi malita 4.5-5.5 a magazi.
Chipatala cha neuralgic cha dongosolo lodabwitsa ili ndi mtima - chiwalo chofunikira kwambiri chomwe chimapumpha magazi nthawi zonse chifukwa chochita maselo. Iyi ndiyo dongosolo lofunika kwambiri, chifukwa zakudya za maselo onse zimadalira ntchito yake yogwira ntchito.
Mwamsanga pamene maselo okhala ndi zakudya amapezeka, magazi amabwerera m'mtima, alowetsa mitsempha yam'mwamba ndi yam'munsi. Kenaka, atakhutitsidwa ndi mpweya wabwino, magazi amapitirirabe kuyenda m'thupi lonse.
Zosangalatsa zokhudzana ndi kufalitsa magazi
- Kusuntha kwa magazi pamtima kumatenga masekondi 4.
- Kuyenda kwa magazi mpaka kumapeto kumatenga masekondi 18, komanso ku ubongo - pafupi masekondi 8.
- Pafupifupi 3,000 mdulidwe wa mdulidwe umachitika tsiku ndi tsiku.
- Kutalika kwa mitsempha yathu ya magazi ndiposa 90,000 km. Izi zikutanthauza kuti akhoza kuzunguliridwa padziko lapansi kawiri.
- Mlingo wa capillary ndi 2500 capillaries pa mamita mamilimita imodzi ya minofu.
Mitsempha - zitsulo zomwe zimayang'anira moyo wa ma cell
Kupeza maselo a zofunikira zonse zowonjezera kumadalira kugawidwa kwa magazi. Ndipo ndi mitsempha yomwe imayambitsa zowonjezera zakudyazi. Pakakhala kuti zakudya zowonjezera zimayamba kugwira ntchito, maselo amamva zovuta, amakakamizidwa kuti azipeza njira yopezera njira zosayembekezereka. Poyamba amatha kupitiriza kugwira ntchito yawo, ngakhale kuti magazi akuyenda molakwika. Koma ndithudi, ili ndi malire. Makamaka mitsempha yotumizira mineral substances, mavitamini, mavitamini, shuga, mafuta ndi mpweya, ndiko kuti, zigawo zikuluzikulu zofunika ku ntchito yofunikira ya maselo onse m'thupi lathu.
Mphamvu ya kukopa
Nthawi zambiri timakhala ndikukhala kapena nthawi zambiri sitimayang'anitsitsa. Choncho, chovuta chachikulu chimene chimagonjetsa mitsempha, kubwerera kwa magazi pamtima, ndicho mphamvu yokopa.
Mitsempha imakhala yosavuta kugwira ntchito yawo, chifukwa izi zimatsogoleredwa ndi kuwonongeka kwa mtima, zofunikira kuti kayendetsedwe ka magazi ka thupi. Mu mitsempha, mosiyana, vuto lifooka.
Choncho, kuti tigonjetse mphamvu yokopa, dongosolo lamatumbo liyenera kukhala ndi zina. Mwachitsanzo, tikamathawa kapena kupita, zovuta zomwe zimagwiritsidwa ntchito ndi chigoba chotchedwa nascent (mbali yokhotakhota ya phazi) imalola kuti magazi afike pamtima. Panthawiyi, njira yokhala ndi mitsempha yamtunduwu imayamba kugwira ntchito, yotchedwa chifukwa ndi malo okhala ndi mitsempha yambiri. Ntchito yaikulu yomwe tangoyamba kufotokozera ndiyo kupereka chiyeso choyamba cha magazi kuti izi zitheke kuwuka pamtima.
Komabe, pali njira zina zomwe zingathetseretu mavitamini omwe amachititsa kuti magazi abwererenso pamtima. Mkokomo wa minofu ya ng'ombe yamtunduwu imakhala ikukula, ikuyesa kupanikizika m'mitsempha yambiri yomwe imakhudza, motero imakankhira magazi pamtima.
Pambali ya mitsempha, pali magulu aang'ono (alibe mitsempha), yomwe imatsogolera mitsempha pamtima. Pomalizira, chofunika kwambiri ndi ntchito ya kupuma, zomwe zimapangitsa kuti magazi aziyenda mozungulira pamene mimba imatulutsidwa kumimba.
Nsomba zakuya komanso zapamwamba zonyansa
Mankhwalawa amakhala ndi mitsempha yambiri ya dimers, yogawira thupi lonse.
Panopa dongosolo lonse la m'munsi mwa thupi lathu (miyendo), liyenera kugawidwa muwiri.
- Mtanda wamtunduwu uli ndi udindo wonyamula magazi omwe atsuka kale minofu. Mitsempha ya makina ozama amapereka kwa mtima 90% mwazi.
- Makina oponyera amagazi amagawira 10% mwazi ndi nthambi mu minofu yapansi. Ndili mumtambo uwu, womwe umapangidwa ndi zilonda zapakati ndi zonyansa, kuti mitsempha ya varicose imakula makamaka. Chokhacho ndi chakuti popeza kuti pokhapokha pokhapokha pokhapokha pokhapokha pokhapokha kutuluka magazi, kuchotsa mitsempha ya varicose sikumayambitsa vutoli.
Khalani bwino!
