Na huhu wurare dabam dabam

A cikin mutane, jini wurare dabam dabam ne wata rufaffiyar hali. Rufe shi saboda shi yana da wani sadarwar da waje muhalli. Bugu da kari, mutum dabam dabam ne cike da kuma biyu. Kammala shi ne ake kira saboda jini (venous da jijiya) ba gauraye.

The jiki saki manyan da kananan wurare dabam dabam. Akwai kuma na uku. Ya kuma ake kira "zuciya", kuma ya aikata quite muhimmanci ayyuka.

Huhu (kananan) wurare dabam dabam zai fara a dama ventricle. Babban aiki shi ne jini oxygen jikewa a cikin kau na carbon dioxide. A cikin huhu akwai musayar gas.

Kananan wurare dabam dabam ne kamar haka. Poor oxygenated jini (venous) shiga daga ventricle (dama) a cikin huhu akwati. Akwati (most jijiya, wanda aka kunshe a cikin huhu wurare dabam dabam) ne zuwa kashi hagu da kuma dama arteries (na huhu). Daga dama kwarara faruwa a cikin hakkin huhu, daga hagu - hagu, bi da bi. Bugu da ari rabuwa auku mahara na huhu jijiya a cikin karami.

Na huhu wurare dabam dabam hada capillaries cewa suna kusa sosai fit da ciki surface daga cikin huhu. Wannan surface da aka tuntube shi tare da na yanayi iska. Jini capillaries a cikin iska ne rabu kawai ganuwar capillaries da kansu sosai haske bakin ciki bango. Wadannan matsaloli ne don haka bakin ciki cewa, a al'ada yanayi, carbon dioxide da oxygen iya shiga ta hanyar su cikin sauƙi. Saboda haka, akwai wani motsi da rabo mafi girma maida hankali a cikin ƙananan rabo. Saboda gaskiya cewa carbon dioxide a cikin jijiyoyinmu more, shi da ke shiga cikin iska, inda shi correspondingly karami. Kuma, kamar yadda a cikin iska kamar yadda yawa oxygen kamar yadda ya wuce a cikin capillaries.

Wasu na huhu capillaries suna da alaka da ƙarƙashinsu a cikin manyan tasoshin. Wadanda, bi da bi, shiga cikin ko ya fi girma tasoshin - da jijiyoyinmu. A sakamakon haka ne hudu manyan jannayẽnsa (na huhu). Saboda haka, na huhu wurare dabam dabam ya zo ga ƙarshe, a hagu atrium.

wurare dabam dabam lokaci kadai ne game da hudu zuwa biyar seconds. Na huhu wurare dabam dabam ya shafi motsi venous jini ta cikin jijiyoyi, da kuma jijiya - ta cikin jijiyoyinmu.

Akwai lokacin da wani cikakken kewaye. A wannan lokaci, da jini ya wuce biyu da'ira - da kuma kananan, da kuma manyan. A sauran, yana daukan game da ashirin zuwa talatin seconds. Tsoka tashin hankali qara gudu. A sakamakon da nassi na jini ta hanyar duka biyu da'irori iya zama daga takwas zuwa tara seconds.

Da yake jawabi na ja ruwa motsi a cikin jiki, shi wajibi ne in ambaci game da gabobin da cewa suna da hannu a cikin ta. Saboda haka, a cikin wurare dabam dabam da hannu ventricles da atria, jijiyoyi, lakã, capillaries, ƙananan kuma babba vena cava, da na huhu capillaries da kuma arteries, veins, da Alveoli, coronaria.

Tare da taimakon da jini za su matsa tsakanin daban-daban gabobin, tsokoki, da kuma zuciya. Daga cikin zuciya zo jijiya. Su kan aika da jini to tsokoki da kuma gabobin. Jijiyoyi bambanta manyan diamita da kuma m na roba ganuwar da cewa zai iya tsayayya da wani isasshe high matsa lamba (jini).

Jijiyoyi an hada da dama bawo: ciki, m da kuma tsakiyar.
