Which name refers to the temporary organ that develops in the uterus during pregnancy?
in humans, a woman becomes pregnant after an ovum and sperm unite (fertilization). After fertilization, a zygote forms. This zygote grows into
a fetus after the eighth week of pregnancy. The fetus receives nutrition from the placenta. The umbilical cord connects the fetus and placenta.
A sac-like structure that medical professionals call the amnion or amniotic sac envelopes the fetus. The sac contains amniotic fluid, which
cushions the fetus and protects it from harm.
