(B)Secretory phase | 2. Follicular phase |
(C)Menstruation | 3. Luteal phase |
a. A – 2, B – 3, C – 1
b. A – 3, B -2, C – 1
c. A – 3, B – 1, C – 2
d. A – 1, B -3, C – 2
Solution
The female reproductive system includes two ovaries which contain many eggs since birth time. At puberty, ovum covers cell masses and matures. Corpus luteum appears when the ovum is released. The endometrial lining supports pregnancy and is removed in case the ovum does not fertilize.
Complete answer:
The female reproductive system includes various events such as pre-fertilization events and post fertilization events. Development and release of the ovum depends on the hormones released in the female reproductive tract.
The follicular phase is also called the proliferative phase. The follicles develop in the ovary and the endometrial cell lining in the uterus increases. This process is known as proliferation.
The mass of cells formed on the ovary when the mature follicle forms known as graafian follicle. It is responsible for the production of the hormone progesterone during early pregnancy. The release and role of the corpus luteum depends on whether the fertilization occurs or not. The secretion of hormones from the corpus luteum occurs in the secretory phase also called the luteal phase. It maintains the uterine wall for pregnancy.
The process of menstruation occurs if the ovum does not fertilize. The flow of cell debris and the blood from the vaginal tract is called menstruation. The breakdown of the endometrial lining occurs and it gets removed from the body with the blood during menstruation.
So, the correct answer is option a that is A – 2, B – 3, C – 1.
Note:
The female reproductive system includes the ovaries, fallopian tubes, uterus, vagina, accessory glands and external genital glands. The female reproductive system performs many functions: produce egg or ovum, transport ovum, fertilize it and nurture the developing fetus. It also produces hormones for the release of ovum and development of the fetus.
