Female reproductive system

Anatomy

• Each month an eggs ripe in the ovary
• A ripe egg enters the fallopian tube = ovulation
• An egg cell meets a sperm cell in the fallopian tube = fertilization 

external female reproductive system

External part of the female reproductive system is called the vulva.

Clitoris: is the pleasure center of the vulva.

Inner labia: Glands in the inner labia produce mucus during sexual arousal. This lubricates the entrance of the vagina so the penis can slide in easier.

What is menstruation?

• Release of blood from the uterus (uterus lining) through the vagina
• Start around age 13

Menstrual cyclye

1. Menstruation

2. follicle phase (eggs cell ripen)

3. luteal phase (build up of endometrium)

4 Phases

• Phase 1 menstruation
• Phase 2: Follicle phase (day 6-12)
• uterus lining build new layer of mucus
• new egg cell develops in the ovary

4 Phases

• Phase 3: Ovulation (day 13-15)
• A new egg cell is released and send down the oviduct (fallopian tube)
• Egg cell survives 24 hours  
  

4 phases

• Phase 4 luteal phase: the body prepairs for pregnancy
•  Endometrium (uterus lining) grows to make a "nest" for the fertilized egg
• No fertilization? Menstruation starts again
