Question

how do humans do reproductions

Answer 1

There are two types of reproduction.we humans and other animals which are multicellular perform mostly sexual form of reproduction.In this,the male germ cell(sperm cell) enters the female reproductive organ through copulation or mating.This male germ cell enters the uterus through cervix and reaches oviduct or fallopian tube.Fallopian tube contains ova( female germ cell) with which the sperm fuses to form zygote and reaches the uterus.Now this zygote is implanted in the walls of uterus and develops into a embryo.The developing child is nutritioned by placenta( tube which connects the mother and baby)and even respiration and excretion etc...Finally the baby comes out after approximately 280 days.
