Chifukwa zilonda minofu pambuyo kulimbitsa thupi lake? Mabaibulo onse

Musanawerenge funso "chifukwa minofu zilonda pambuyo kulimbitsa thupi ndi," kuwerenga mfundo zina zokhudza mbali yofunika imeneyi ya thupi lathu. minofu anthu mokwanira lovuta dongosolo minofu. Okwana pali mitundu itatu ya minofu - mtima, yosalala (kuchepetsa matumbo khoma, mitsempha ya magazi, etc.) Ndipo chigoba -. Mbali chigoba kusuntha wachibale wina ndi mzake. yotsirizira zachokera lalikulu (14 cm) minofu selo CHIKWANGWANI, amene ali unit zikuluzikulu za njira contractile. ulusi asonkhana mu mitolo, amene pamodzi kupanga mkono chikugwirizana mafupa ndi tendons. akulu ulamuliro dongosolo zachitika likuvutika axons - maselo mitsempha kuti nthambi kuti ali oyenera wina CHIKWANGWANI.

vuto, chifukwa zilonda minofu pambuyo thupi, chidwi oyamba ambiri. Kuthetsa vuto limeneli, muyenera kudziwa ena ndizosowa sayansi:

- ulusi minofu ndi kuchepetsedwa chifukwa mphamvu anachokera ku ATP;

- ATP malo mu minofu ndi zochepa kwambiri;

- ATP kubwezeretsa ikuchitika ndi glycolysis - Kutha kwa mamolekyulu shuga kwa asidi lactic ndi kutulutsidwa kwa mphamvu zofunika kaphatikizidwe ATP ;

- mphamvu akupezeka pogawanikana pamawere wa creatine kupereka acid ndi ADP;

- komanso akhoza kulandira mphamvu mwa thupi, pamene mpweya, shuga, ndi ADP kupeza madzi, mpweya woipa ndi adenosine triphosphate.

Monga tikuonera, mu mapangidwe mphamvu m'zochitika zonse mu mankhwala anachita zikuoneka asidi limafotokoza zimene zimachititsa minofu zilonda pambuyo kulimbitsa thupi ndi. Pali kumverera kwa "ouma" malire kuyenda, amene angakhalemo tsiku kuposa wina, ngati mulibe njira zina. Ngati minofu zilonda pambuyo kulimbitsa thupi, ndiye muyenera mndandanda wa njira zothetsera acidity. Izi ntchito ndi zochangamutsa ndi ofunda shawa atangotha masewera olimbitsa thupi komanso kuchuluka pang'onopang'ono katundu amene amayamba maphunziro kwa zikande. Hot mphika ndi kuvomereza ascorbic asidi amapereka vasodilatation. Ndipo, ndithudi, musaiwale za kudya mokwanira zofunika njira zonse zokhudza thupi.

Kodi kuthetsa ululu mu minofu pambuyo kulimbitsa thupi, pamene kumachitika Mwachitsanzo, mu tsiku? Mtundu uwu wa othamanga thupi mavuto amatchedwa "mtsogolo" ululu. Iwo kwambiri zimakonda ndi microtrauma mu ulusi minofu (myofibrils Mwachidule), zimachitika katundu pamene kwambiri. Apa, chifukwa cha kuchuluka zina za madzi amaperekedwa kwa selo solubilize lysosomes zowonongeka mikrooteki uka, amene ululu. Othamanga ndi zinachitikira myofibrils lalifupi ang'ono, kupweteka kwa dongosolo ngati iwo ali ndi mwayi wochepa.

Nthawi zina vuto ndi chifukwa minofu zilonda pambuyo thupi, amagwirizana ndi njira yaikulu kwambiri kuti asanene loletsa zosakhalitsa ntchito iliyonse yaikulu masewera. Pankhaniyi, izo zikanakhoza kukhala minofu mavuto kapena mitsempha chophukacho. kuwonongeka kale amafunika opaleshoni. Koma kuwonongeka kwa minofu CHIKWANGWANI mankhwala oyamba superposition zolimba bandeji ndi kutsatira ulesi mode, namtsata (patapita masiku angapo) ntchito n'kumawotha zodzola kwa mofulumira njira kusinthika.
