Question

Answer

Inside the ovary is the ovarian cavity (locule). The placenta is located inside the ovarian cavity. Arising from the placenta are the megasporangia, commonly called ovules.

Answer

Because ovarian cavity is female reproductive part and development of fetous occurs in uterus of mother so due to presence of placenta fetous gets nourished up to birth

Answer

D

Answer

The correct answer is option 'D': Ovarian cavity.

Explanation:
The placenta is an organ that develops during pregnancy in mammals and serves as an interface between the mother and the developing fetus. It plays a crucial role in providing oxygen, nutrients, and waste removal for the fetus, as well as hormone production.

Placenta Location:
The placenta is typically located inside the ovarian cavity. This is because the placenta develops from the chorionic villi, which are finger-like projections that extend from the outer layer of the embryo, called the chorion. The chorionic villi invade the lining of the uterus, known as the endometrium, and establish connections with the maternal blood vessels, allowing for the exchange of substances between the mother and the fetus.

Process of Placental Development:
1. Implantation: After fertilization, the developing embryo undergoes implantation into the endometrium of the uterus. The chorionic villi then develop from the outer layer of the embryo.

2. Invasion: The chorionic villi invade the endometrium and establish connections with the maternal blood vessels. This allows for the exchange of oxygen, nutrients, and waste products between the mother and the fetus.

3. Placental Formation: As the chorionic villi continue to develop and expand, they form the placenta. The placenta consists of both fetal and maternal tissues and is attached to the uterine wall.

4. Function: Once formed, the placenta serves as a barrier between the maternal and fetal bloodstreams. It allows for the transfer of substances such as oxygen, nutrients, antibodies, and hormones from the mother to the fetus, while also removing waste products from the fetal circulation.

In summary, the placenta is located inside the ovarian cavity, as it develops from the chorionic villi that invade the endometrium and establish connections with the maternal blood vessels. This location allows for efficient exchange of substances between the mother and the developing fetus during pregnancy.
