Thick muscular, pear shaped
Growth of developing fetus and embryo
Nutritional support for fetus - Development of Placenta

18

21
Q

Describe the pathway of the egg (Not fertilised)

A

An egg is released from one of the ovaries

If the egg is not fertilised it starts to break down as it is moved through the uterus to the vagina
Egg then passes out of the body
