Ƙunƙarar ƙwaƙwalwa sun ƙunshi ƙananan ƙwayoyin da aka tattara a cikin tayun. A ciki daga cikinsu sun wuce cikin zaren, wanda ya kunshi sunadarai, godiya ga abin da aikin asali - raguwa ya cika.

Kwayar tsoka ta Cardiac yana da tsarin kama da ƙananan ƙwayoyin cuta. An haɗa su a sassa dabam. Dangane da wannan yanayin, ƙwayar zuciya tana iya saurin haɓaka.

Jigun hankalin mutum yana iya kasancewa a ganuwar duk gabobin ciki. Raguwa a cikin ƙwayoyin fiber muscle yana jinkirin.

Yatsun ɗan adam suna da kyakkyawar innervation da wadatar jini. Ga kowace ƙwayar tsoka, jijiyoyi, jini yana dace. Suna da harsashi, wanda nau'in haɗi ne yake wakilta. Jijiyoyin da ke kula da tsokoki suna dauke da motoci da masu amfani da ƙananan. Tsohuwar motsawar motsi daga kashin baya, sakamakon sakamakon ƙwayoyin tsoka. Sabili da haka, tsokoki a cikin jiki suna sanya shi a hankali. Jirgin da ke fitowa daga kashin baya ya shafi kwakwalwa. Sabili da haka, ayyukan sun zama masu tsauri. Tare da rikitarwa, ana tilasta tsokoki don motsa sassa daban daban na jiki, wanda zai haifar da motsi jiki ko adana wani matsayi. Ana samun wannan sakamako ta hanyar haɗin gwiwa da kuma ƙaddamar da aikin ƙwayoyin ƙwayar da ƙuƙwalwar, wanda ke aiwatar da wasu ayyuka.

Human tsokoki yi inji aiki. Suna yin kwangila kuma suna aiki a kasusuwan a matsayin mai hazo. Duk wani motsi yana buƙatar mai yawa makamashi.
