Ura womunhu uye ake anatomi

Human ura chimwe zvomudumbu turakiti uye rinotanga pedyo pylorus uye rinopera rwemberi buri. Mumamiriro muviri kwakadaro, pane kunyatsogayiwa zvokudya uye Absorção de Água vose zvinhu zvayo. Zvinofanira kucherechedzwa kuti intestinal nhengo chinoita rakakura basa romuviri rinodzivirira zvirwere.

Aripiko ura vanhu? Nechipiriso Nhengo riri abdominal nzvimbo (nechepasi) uye anotora nayo zvikuru. Sezvo chikazozikamwa, zvachose urefu yevanhu ura anenge mana meters (noupenyu) uye anenge 500-800 masendimita pashure porufu. Vachangoberekwa, kureba muviri zvichisiyana 340 masendimita kusvika 360 pakupera kwegore upenyu rokutanga, izvozvo kunowedzera nokuda vanenge 50% uye akapfuudza kukura mwana 6-7 nguva.

Anatomy womunhu ura

Chinzvimbo, chimiro uye mamiriro muviri kuchinja panguva kuibvisa. Mukuru kusimba kukura kwakacherechedzwa munguva kubva pakutanga gore kusvika 3 years. Izvi imhaka yokuti mwana zvishoma nezvishoma anova neveMamwe kunopindirana kudya.

Anatomically, vanhu ura rakakamurwa zvinotevera mapoka:

• dzakaonda;
• gobvu.

First chidimbu chimwe zvomudumbu ino iyo unongoda pakati muura uye mudumbu. Mumuviri uyu kuuya zvose huru dzinotsanagura kugaya. Its zita duku ura vanosungirwa kuti masvingo aro vari zvishoma nesimba pane guru ura rusvingo. Mukuwedzera, pakakoromoka uye mhango kwomuviri, zvakare, iduku zvikuru.

Uyewo, dzakaonda dzevanhu ura rakakamurwa zvinotevera zvikamu:

• 12 tiperstnoj ura;
• dzakaondoroka;
• ileum.

The guru ura ndiyo yepazasi kuguma chikamu zvomudumbu turakiti. Zvinonzi vakanwa kuuya mvura uye paumbwe fecal chyme. Zita iri vakagamuchira ura nokuti kuti masvingo aro vari mukobvu kupfuura masvingo yapfuura kadhi. Zvinokosha kucherechedza kuti wakadaro simba, simba zvakafanira tsandanyama uye connective tishu rukoko. The dhayamita pamusoro muura uye yaro yomukati lumen (mhango) ndiko yakakura kupfuura ura diki.
