Answer 1

Answer:

Explanation:

Menstruation (Days 1-6)

Follicles immature

Uterus lining breaks

Pituitary gland releases FSH

Proliferation (Days 7-13)

Eggs begin to develop

Uterus lining repairs

FSH causes new egg to develop and oestrogen release. Oestrogen stops FSH (prevents more eggs developing), starts LH release and uterus lining thickening.

Ovulation (Day 14)

Follicle releases egg

Uterus lining remains thick

High LH level causes follicle to bust and release egg into oviduct

Ovulation (Days 15-28)

Egg moves down the fallopian tube

Uterus lining remains thick

Answer 2

Answer:

1.luteal phase

2.Luteal phase (day 15-28)

If a sperm cell does not impregnate the egg cell within that time, the egg cell disintegrates.

3.Day 1 starts with the first day of your period. The blood and tissue lining the uterus (womb) break down and leave the body. This is your period. For many women, bleeding lasts from 4 to 8 days

4.Luteal phase (day 15-28)

This phase begins on the 15th day and lasts till the end of the cycle. The following events occur during this phase: The egg cell released during the ovulation phase stays in the fallopian tube for 24 hours

5.Lots of girls experience cramps before or during their periods. Cramps are caused by prostaglandins (say: pross-tuh-GLAN-dinz), chemicals a girl's body produces to make the muscles of the uterus contract. The contracting muscles help push the blood out through a girl's vagina during her period.
