Healthy jini: wani rai ba tare da cututtukan zuciya da na

A jini a cikin jiki da hidima a matsayin wani a haɗa kashi ga m aiki na kowane cell na kowane sashen. Its motsi a cikin jiki ne ake kira wurare dabam dabam, ta hanyar abin da oxygen, hormones da kuma gina jiki ciyar da duk tsokoki da kuma gabobin, kuma daga can tare da taimakon fitarwa kayayyakin da bazuwar na sharar abubuwa. Bugu da kari, jini daukawa fitar thermoregulation na jiki, da kuma kare shi daga cutarwa microbes. Ci samar da Sistem jini da kuma zuciya cewa yin up da jijiyoyi, duk wanda ayyuka suna tsananin hadewa.

Jini, overall wanda a hade tsawon shi ne 100 dubu. Km, shi ratsa jikin mutum kamar wata katuwar yanar gizo, kyale kowane cell oxygenated. Jini ya kwarara faruwa kai tsaye ta hanyar da jijiyoyi, jijiyoyinmu da capillaries.

Jijiya - a lokacin farin ciki-hananna kayayyakin da samar da jini ya kwarara zo daga zuciya. Su ne sosai m kuma, dangane da girma na pumped jini da zuciya iya fadada ko kwangila. Jijiyoyi kawo jini wadãtar da oxygen inhaled, cewa shi ne "tsabta". Vienna, da bambanci, nuna jini outflow cika da carbon dioxide. A cewar shi jinin motsi zuwa ga zuciya. Jannayẽnsa ganuwar kasa m fiye da jijiyoyi. Capillaries su ne mafi karami jini tare da wani bakin ciki sosai bango ta hanyar abin da dawowar jini a cikin sel oxygen da kuma gina jiki da kuma carbon dioxide nassi da kuma musayar jini kayayyakin a cikin cell.

A impetus ga motsi na jini ne bugun zuciya. The motsi na jini ya auku ta biyu da'irori: kananan (na huhu) da kuma na tsari wurare dabam dabam, ci gaba da kwarara. Lokacin da tuki a kan kananan da'irar yana da warware daga carbon dioxide da oxygenated. A babban da'irar, a maimakon haka, ba daukawa oxygen da kuma gina jiki, shan carbon dioxide da sharar gida kayayyakin.

Human jini taka muhimmiyar rawa a cikin jikin ta m tafiyar matakai. Su ba a banza da ake kira "rai arteries": tying tare da kusan duk Kwayoyin na jiki, sun tabbatar da jitu aiki.

Masana kimiyya ce cewa jini suna tsufa kuma sa kadan kafin sauran na jiki ta tsarin.

Slagging tasoshin take kaiwa zuwa tabarbarewar jinin samar da jiki, wanda a bi sa nama rashin muhimmanci na gina jiki. Saboda haka mu ne masu tasowa duk aka sani cuta, kuma tun akwai jiki ta tsufa.

Cututtukan zuciya tare da ciwon sukari da kuma ciwon daji zuwa ranar, da tabbaci rike da dabino daga mafi hadarin da tartsatsi cututtuka. A wani rukuni na cututtuka na zuciya da jini ne da wadannan:
