Namtsata anthu kufalitsidwa: kapangidwe ndi udindo mu thupi

Magazi - kupanga chilengedwe mkati mwa thupi la munthu ndi dongosolo lalikulu zoyendera monga umagwira ntchito osati zawo, komanso maselo a chitetezo cha m'thupi. Madzi a m'magazi Mapuloteni anatitumiza kuti zimakhala onse mahomoni, chakudya ndi mpweya, ndi kupereka yokonza kutentha homeostasis.

Mogwirizana ndi izi ndi mabwalo a anthu magazi, kapena kani, dongosolo zinchito, kuphatikizapo mtima wa ziwiya lalikulu, mitsempha ndi mitsempha ya sing'anga ndi yaing'ono malamulo komanso capillaries amapanga microcirculation. Onsewo ali zawo wapadera kapangidwe ndi njira za lamulo. Chifukwa cha nyama apamwamba ndi mtima zinayi chambered, adafuna kusiyanitsa chachikulu ndi yaing'ono makope wa munthu. Komanso, komanso olekanitsidwa ubongo ndi mtima, chifukwa iwo ndi zina zapadera. Kwa nthawi yoyamba atulukira malamulo onse a dongosolo lino wapanga William Harvey mu zoyambirira za m'ma 17, ndipo kenako deta ndi kudzadza monga patsogolo kwa kudziwa pa thunthu ndi Maphunziro Akakhalidwe Kazolengedwa, anafotokoza hemodynamic ndi katundu rheological magazi, komanso njira zochenjera kuyenda ake kudzera ziwiya.

kapangidwe

Makope wa munthu sipangakhalenso popanda ulamuliro wa chapakati dongosolo - mtima. Ndi dzenje, kapena kani, chipinda, akulu thupi, omwe amanyamula mphamvu ya contractions ake zoona, mphamvu ya magazi. Ndipo m'tsogolomu zimathandiza kuti izi ndi kuchita ziwiya, kapena kani, linga lawo akulu. A bwalo lalikulu la magazi munthu amapereka trophic ndi mpweya pafupifupi thupi lonse: ndi torso, miyendo ndi ziwalo. Kawirikawiri kuchoka Chipilala kung'ambika anachoka wamba carotid mtsempha wamagazi (aa.carotis communis) ndi brachiocephalic thunthu (truncus brachiocephalicus), kupereka mphamvu ubongo. Zina nthambi ya chotengera waukulu, umene akuyamba mu ventricle kumanzere, ndi awiri subclavian mtsempha wamagazi (aa.subclavia dexter neri yolakwika), ndiyeno - axillary (aa.axillaris) ndi phewa (aa.brachialis), kupereka magazi m'manja. Ziwalo zonse m'mimba, mafupa a chiuno ndi m'munsi nthambi trophism analandira mwa msempha m'mimba. Itha zokhudza zonse makope m'munsi ndi chapamwamba mitsempha dzenje loyenda mu atrium bwino. mapulogalamu ndi zosavuta, chifukwa mu alveoli za thupi pali wina njira zofunika kwambiri - mpweya kuwombola pakati pa capillaries ndi sacs mpweya magazi akubwera kuchokera ventricle kumanzere mwa thunthu m'mapapo mwanga, olemera ndi mpweya ndi wotaya mpweya. Ndiye Libwerere ku mtima mu ventricle kumanzere kwa vv.pulmonales. Zimenezi zimapangitsa bwalo ka anthu magazi.

Kulankhulana ndi machitidwe ena

Kumene, yofunika kwambiri ndi chikhalidwe cha ziwiya mtima ndi magazi, izo zimatengera iwo liwiro ndi phindu la trophic ndi kupuma ziwalo zina zonse ndipo zimakhala. Komabe, aliyense m'deralo kapena zokhudza zonse njira pathological m'thupi bwanji zotsatirazi anthu magazi ndipo zingachititse atherosclerosis, matenda oopsa, kuwonjezera katundu pa mtima. Choncho, kuti uziyenda bwino za dongosolo lino n'kofunika kwambiri thanzi wonse wa thupi.
