Answer 1

Hrana este digerata prin intermediul aparatului digestiv. Procesul prin care are lor transformarea hranei in substante necesare organismului, si anume in nutrimente,  se numeste digestie. Nutrimentele intra in circuitul sangvin prin absorbia lor de catre intestinul subtire.Celulele corpului au nevoie de aceste nutrimente. Totodata asigura corpului si energia necesara. Sistemul respirator asigura corpului oxigenul necesar vietii.
Prin respiratie se elimina dioxid de carbon. In afara de hrana si oxigen corpul uman are nevoie si de apa.
