Female Reproductive System

• Anatomy of A Female Reproductive System:

  Ovary

  Fimbriae

  Fallopian Tube

  Endometrium

  Uterus

  Cervix

  Vagina
• Ovary site of oogenesis; produces hormones estrogen and progesterone.
• Fimbriae picks up the ovum from the ovary.
• Fallopian Tube is a passage from ovary to Uterus; site of fertilisation. Also called as oviduct.
• Endometrium nourishes the embryo; sheds during menstruation.
• Uterus site of eggs implantation; embryo development
• Cervix is the muscular opening of the uterus.
• Vagina is the entrance of the penis, also called as birth canal.
• Females have 2 ovaries, which alternate each month to produce an egg/ovum.
• Ovaries contain 400,000 egg cells, but only 400 actually mature between the ages of 12 - 50.
• Pathway of the Sperm:

  Vagina

  Cervix

  Uterus

  Fallopian Tube
• Hormones are chemical messengers of the body. They are important to maintain homeostasis.
• (FSH) Follicle-Stimulating Hormone signals development of egg cells (oogenesis).
• (LH) Luteinizing Hormone plays a role in the development of ova, and stimulation of estradol and progesterone production.
• Estrogen is instrumental in breast development, fat distribution in the hips, legs and breasts, and the development of reproductive organs.
• Estrogen is secreted by ovaries PRIOR to ovulation.
• Progesterone helps prepare the body for potential pregnancy.
• Progesterone prohibits muscle contractions in the uterus that would cause the body to reject the egg
• Progesterone secreted by ovaries AFTER ovulation
• Progesterone levels become low and menstruation happens if egg is not fertalized.
