Why does the uterus have muscular walls?

The uterus is shaped like an upside-down pear, with a thick lining and muscular walls — in fact, the uterus contains some of the strongest muscles in the female body. These muscles are able to expand and contract to accommodate a growing fetus and then help push the baby out during labor.

The uterine wall is made up of three layers of muscle tissue. The muscle fibres run longitudinally, circularly, and obliquely, entwined between connective tissue of blood vessels, elastic fibres, and collagen fibres. This strong muscle wall expands and becomes thinner as a child develops inside the uterus.

What is Oogenesis?

oogenesis, in the human female reproductive system, growth process in which the primary egg cell (or ovum) becomes a mature ovum. These cells, known as the primary ova, number around 400,000. The primary ova remain dormant until just prior to ovulation, when an egg is released from the ovary.

Which part of the uterus opens to the vagina?

The cervix
The cervix is the lower part of the uterus that opens into the vagina. During childbirth, the cervix expands about 4 inches (10 centimeters) so the baby can travel from the uterus through the vagina and into the world.

What happens to wall of uterus during menstruation?

Menstruation is one part of a woman’s cycle when the lining of the uterus (endometrium) is shed. This occurs throughout a woman’s reproductive life. With each monthly cycle, the endometrium prepares itself to nourish a fetus. Increased levels of estrogen and progesterone help thicken its walls.
