Jijiyoyi kuma su Ayyuka
Jijiyoyi ake kira da kayayyakin a cikin abin da jijiya jini ya kwarara. Kuma su ne ta kawai daga zuciya. The most jikin mutum jirgin ruwa, cikinsa da qoramu jini, arziki a oxygen, ne lakã na lafiya adult adam, da diamita ne 2.5 centimeters. Arterioles iya isa kawai 0.1 millimeter. Kai tsaye kusa da wani reshe na lakã na zuciya shi ne mai arziki a cikin roba zaruruwa, sun yi laushi da bugun jini kalaman wanda ya ba da zuciya da kuma jijiya jini sa'an nan gudana a ko'ina ta hanyar da tasoshin. A wannan hanya, oxygen ne a hankali canza kama zuwa masana'anta. Next, da jirgin ruwa ganuwar ba su kamar yadda supple kuma saya mafi yawa, da farko saboda gaban tsoka zaruruwa. Jijiya nasaba da sauran arteries, shi ne ake kira collaterals, saboda clogging su tare da daya jirgin ruwa da jini zai iya tafi da wasu. Kowane sashen jikin mutum ne kullum jiran da oxygen, wanda shi ne don haka dole a matakai na samar da makamashi metabolism. Babban aiki na arteries ne da isar da jini don su maza maza. A erythrocytes yawa oxygen, don haka da launi na jijiya jini - mai haske ja, yayin da cuts tasoshin yana da wani marmaro, sama da dukan, saboda da matsa lamba da ta wanzu a gare su.
