Female reproductive system

Question 1

ovaries

Answer 1

two female gonads that produce one ova each month.
where oogenesis occur

Question 2

follicles

Answer 2

specialized cells in which a single ovum develops. Each month only one of the 20-30 follicles mature and then ruptures releasing the ovum into the oviduct, which is called ovulation

Question 3

process

Answer 3

After ovulation, thread like projections called fimbriae sweep the ovum into the cilia lined tube of 10 cm called oviduct. The oviduct carries the ovum from the ovary to the uterus. Within the oviduct, the beating cilia create a current that moves the ovum towards the uterus.

Question 4

Ovum

Answer 4

A mature ovum in a non-motile, sphere shaped cell 0.1 mm in diameter. the ovum contains large amounts of cytoplasm, which contains nutrients for the first days of fertilization.

Question 5

Uterus

Answer 5

uterus is a muscular organ that holds and nourishes a developing fetus. The lining of the uterus, called the endometrium, is richly supplies with blood vessels to provide nutrients for the fetus.
uterus connects to oviduct on the upper end, and at its base, it forms a narrow opening called cervix, which connects to the vagina.

Question 6

ovum survival

Answer 6

The ovum survives in the oviduct for up to 24 hours after ovulation. If a living egg encounters sperm in the oviduct, fertilization may take place. The fertilized egg, now called a zygote, continues to move through the oviduct for several days before reaching the uterus. During this time, the endometrium thickens as it prepares to receive the zygote. The zygote implants itself in the endometrium, and development of the embryo begins.

Question 7

Menstruation

Answer 7

If fertilization does not take place, the endometrium disintegrates, and its tissues and blood blow out the vagina in a process called menstruation.
