Placenta is the structure connecting foetal membrane and the inner uterine wall. It is formed by many finger like projections growing into the uterus from the outer surface of the chorion, called villi. It is described as deciduate, discoidal and haemo-chorionic.
The functions of placenta are:
1. It is nutritive, respiratory and excretory system for foetus: provides oxygen, glucose, amino acids, lipids, minerals, vitamins and other nutrients, taking away carbon dioxide and waste materials.
2. It functions as an endocrine gland secreting hormones such as lactogen, oestrogen/progesterone and human chorionic gonadotropin(HCG).
3. During Parturition: When ACTH is released, steroidal hormones are secreted. This stimulates placenta to produce prostaglandins, which is necessary for muscular contractions.
4. Provides antibodies acting as foetus' immune system.
