Biology

Not quite remember

I easily remember

Menstruation

Rupture of the lining of the uterine wall and the blood flowing through the vagina

Menstrual cycle (1)

Involves the production of a secondary oocyte and thickening of the endometrial wall throughout one cycle

The importance of endometrium thickening

Supplying blood vessels in preparation for embryo attachment

Effects of fertilization that do not occur

Secondary oocytes will die and the endometrium will rupture and lead to menstruation

Ovulation

A process to release the secondary oocyte from mature Graafian follicle to be fertilized by sperm

Location of fertilization

Occurs in the Fallopian tube

The role of follicle-stimulating hormone (FSH) in the menstrual cycle (1)

Stimulates follicle growth in the ovary

The role of estrogen hormone in menstrual cycle

Stimulates the endometrium thickening

The role of progesterone hormone in menstrual cycle

Prepares the endometrium for zygote implantation

The role of HCG hormone in pregnancy

Maintains the corpus luteum at the early stage of pregnancy to supply progesterone and estrogen continuously
