Hint: The placenta is an endocrine gland formed in the uterus of a pregnant woman. It provides oxygen and carbon dioxide, as well as nutrients between the mother and the fetus. Human chorionic gonadotropin( HCG), Progesterone, Estrogen and human placental lactogen are the hormones secreted by placenta.
What is the endocrine function of the placenta?
The placenta also acts as an endocrine organ, producing several important hormones during pregnancy. These hormones work together to control the growth and development of the placenta and the fetus, and act on the mother to support the pregnancy and prepare for childbirth.
What are the functions of placenta other than its endocrine function Class 12?
Other than the endocrine function, placenta also facilitates the supply of oxygen and nutrients to the embryo and removes carbon dioxide and excretory/waste materialsproduced by the developing faetus.
Which layer of placenta is endocrine in function?
This organ plays essential roles during gestation, including fetal nourishment, support and protection, gas exchange and production of several hormones and other mediators. Placental hormones are mainly secreted by the syncytiotrophoblast, in a highly and tightly regulated way.
How placenta acts as an endocrine tissue explain?
The placenta secretes hormones like human gonadotropins, human placental lactogen, oestrogen and progesterone that are necessary to maintain pregnancy. Due to the secretion of these hormones, it is called an endocrine gland.

What is parturition Class 12?
Parturition means childbirth and it is a neuroendocrine mechanism and it occurs when a fully developed foetus and placenta produces the foetal ejection reflex. … Parturition begins with the dilation in which the posterior lobe of the pituitary releases the oxytocin hormone (birth releasing hormone).
What secretes chorionic gonadotropin?
Human chorionic gonadotropin is a hormone produced primarily by syncytiotrophoblastic cells of the placenta during pregnancy. The hormone stimulates the corpus luteum to produce progesterone to maintain the pregnancy. Smaller amounts of hCG are also produced in the pituitary gland, the liver, and the colon.
What tissue does the placenta originate from?
The fetal component of the placenta, called the chorion frondosum, develops from the fetal blastocyst, while the maternal component, called the decidua basalis, develops from the maternal uterine tissue. Placental development is initiated after fertilization and implantation.

What is endocrine tissue?
Endocrine cells within endocrine glands release hormones conveyed particularly by the bloodstream and can act on distant cells: examples of endocrine glands being the anterior pituatry, the thyroid gland and the adrenal gland. …
How is the placenta connected to the embryo?
The fetus is connected to the placenta through the umbilical cord, a tube that contains two arteries and a vein. … Blood from the fetus enters the placenta through the umbilical arteries, exchanges gases and other substances with the mother’s blood, and travels back to the fetus through the umbilical vein.
