Placenta is a disc like structure attached to the uterine wall. The placenta is formed of two sets of minute finger like processes, the villi. It acts  as the linkage between the mother and the growing embryo.
Function:- The placenta allows diffusion of substances from the mother to the foetus(oxygen, Nutrients such as glucose/amino acids/vitamins/mineral ions) and from foetus to the mother(carbon dioxide and urea).
Placenta also acts as an endocrine gland. It produces the hormones called oestrogen and progesterone.
