Solution
The two main components of the placenta by the beginning of the fourth month of pregnancy are:
a. Chorion frondosum and decidua basalis
The chorion frondosum is the fetal component of the placenta, and it develops from the chorionic sac. It contains the chorionic villi, which are finger-like projections that extend into the maternal blood supply, allowing for the exchange of nutrients and waste products between the mother and fetus.
The decidua basalis is the maternal component of the placenta. It is the part of the endometrium (the lining of the uterus) where the placenta attaches. It provides the blood supply for the placenta, allowing nutrients and oxygen to be transferred to the fetus and waste products to be removed.
