Question

Choose the correct:

1. (A) Ampulla - Site of blastocyst implantation
2. (B) Fimbriae- Collect ova
3. (C) Myometrium - Shed during menstrual bleeding
4. (D) Ovary - secrete HCG

Answer 1

Hint: The uterus is part of the reproductive system in females and anatomically can be divided into four regions: the uppermost rounded portion of the uterus called the fundus, the corpus (body), the cervix, and the cervical canal. The ovaries produce eggs, and these eggs travel through the fallopian tubes. Eggs can be fertilized once they have left the ovary and implant themselves in the lining of the uterus.

Complete answer:
The fimbriae of the uterine tube are called fimbriae tubes. These are small, finger-like projections at the end of the fallopian tubes. These help move from the ovaries to the uterus. These collect ova.
The ampulla is the third part of the fallopian tube. It is an intermediate and dilated portion that curves over the ovary. It is a common site of fertilization and early embryo development in humans.
The middle layer of the uterine wall is called the myometrium. It consists of uterine smooth muscles and stromal and vascular tissue. The primary function of the myometrium is to induce uterine contractions.
The ovaries perform two main reproductive functions in the body: producing oocytes (eggs) for fertilization and producing reproductive hormones such as estrogen, and progesterone.
HCG is a hormone that is produced by the placenta after implantation. HCG stimulates progesterone production by corpus luteal cells and also promotes angiogenesis in uterine vasculature.

So, the correct answer is option (ii).

Additional Information:
The innermost lining of the uterus is called the endometrium. The endometrium thickens and renews itself every month, preparing for pregnancy. When pregnancy doesn't occur, the endometrium sheds, and the process is called menstruation. If conception happens, the embryo embeds into the endometrium.

Note: The pregnancy test utilizes the higher levels of human chorionic gonadotropin (HCG) in the body of the female. The test is done to measure the level of the hormone HCG in blood or urine to determine if a woman is pregnant. HCG can also be measured to test the presence of cancer of ovaries or testicles.
