Which of the following prevents the foetus from dehydration and shocks?
Amniotic fluid
Foetus attaches itself to the walls of the uterus through the placenta. Placenta is made up of both foetal tissues and uterine tissues. The foetus is inside the amniotic sac or amnion of the placenta, which is filled with the amniotic fluid. Amniotic fluid prevents dehydration and acts as a shock absorber for the foetus. Foetus is supplied with oxygen and nutrients by the umbilical cord.
