Female Reproductive System Vagina/Birth Canal – female sex organ, passageway for the baby during birth. Uterus - muscular organ, houses developing fetus, stretches over 40 weeks. Lining of uterus is called Endometrium – this sheds each month when a girl menstruates. Cervix – opening from birth canal to the uterus. This will dilate (open) to 10cm prior to birth. Fallopian Tubes – “tunnel of love” – egg and sperm unite in fallopian tube (conception/fertilization) Ovary(ies) – Eggs are stored here, released from here once a month beginning in puberty. Females hormones are also produced here. Fimbre – hairlike structure that helps move the mature egg out of the ovary and into the fallopian tube. *Draw Cilia – tiny hairs that help the egg move along once inside the fallopian tubes.

Vas Deferens – Sperm highway – sperm travel from the epididymis to the urethra. Bladder – holds urine Seminal Vesicle – produces fluid – which is part of the semen.. This fluid is high in carbohydrates/sugar and provides nutrition and energy for the sperm. Cowpers Gland – produces the first fluid – part of the semen, which neutralizes or cleans out the urethra prior to ejaculation. Epididymus – holds mature sperm.

Taking deep breaths is a difficult task. Before delivery the baby “drops,” making breathing easier. Some women experience heart palpitations. The body volume has increased and sometimes the heart has to work overtime. However, the heart can stand the strain.
