Question

Several hormones like HCG, hPL, estrogen and progesterone are produced by
A. pituitary
B. Ovary
C. Placenta
D. Fallopian tube

Answer 1

Hint: Placenta is found in all viviparous, oviparous and intimate the connection between the fetus and urine wall of the mother to exchange the food material to the fetus. Placenta helps to maintain the oxygen level, provide minerals, nutrition’s, gases exchange, and excretion material change through the help of the placenta. Placenta plays an interdigitated role between the fetus and mother.

Complete answer:
Placenta is a rod-like structure that is bound to the umbilical cord. Umbilical cord helps to exchange the material between the fetus from the mother and after delivery umbilical cord separate from the both. Placenta is not a simple membrane, it is obtained by two different tissues from two different bodies that includes epithelium, connective tissue and blood capillaries are also constituents of it.
The chorion is part of the embryonic tissue that is also known as human chorion placenta and yolk sac also part of the placenta formation. Placenta is mostly formed by embryonic chorion and allantois membrane and also presented as a true placenta. And the true placenta is found in the t gain mammals.
The placenta secreted mainly two steroids hormones like estradiol and progesterone and two proteins hormones like human chorionic gonadotropin HCG and human placental somatomammotropin HCS. relaxing is also secreted by placenta which helps in the delivery contractions.

Therefore the correct option is (C ).

Note: The HCG helps to determine the confirmation of the pregnancy. If the HCG level increases it confirms the pregnancy test. Corpus luteum solution help to prevent the abortions and growth the mammary glands. Placenta material exchange by diffusion, pinocytosis, and active transport. Placenta produce antibodies for measles, chicken pox, polio that’s present in the blood of mother reach the embryos through placenta.
