Answer :

Final answer:

Menstruation signifies reproductive capability in females and occurs when no fertilization happens. It involves shedding of the uterine lining, typically supported by hormonal processes that coordinate the menstrual cycle. Key hormones like progesterone and estrogen play significant roles in regulating these processes.


Explanation:

Understanding Menstruation and the Female Reproductive System

Menstruation is a key aspect of the female reproductive system. It typically signifies that a girl is capable of producing offspring (Question 2: C). Menstruation occurs when the uterine lining is shed because fertilization did not happen, which relates to Question 11 (A). Blood is discharged from the uterine wall through the vagina (Question 3: C, D).

The cycle involves several hormonal changes. An egg is released from the ovary through ovulation (Question 4: D), typically around the 14th day of a regular cycle (Question 5: B). The ovaries, which produce ova and secrete hormones such as estrogen and progesterone, are crucial (Question 6: B). Among hormones, progesterone particularly prepares the uterine lining for implantation (Question 8: D).

The menstrual cycle has different phases depending on fertilization; without fertilization, menstruation occurs due to the shedding of the uterine lining. The uterine cycle consists of a sequence of growth and shedding of the endometrium (Question 9). Importantly, the feedback mechanisms regulate hormones involved in this cycle (Question 12).
