Development Physical – Males and females will go through puberty, or the period of growth when a person begins to develop certain traits of adults of his or her own gender. Puberty is controlled by hormones, or chemical substances that regulate the activities of body cells and organs. Hormones are controlled by the Endocrine system, or the body system made up of ductless glands that secrete hormones into the blood. The endocrine system is controlled by the pituitary gland, located at the base of the brain.

Puberty Males – The pituitary gland controls the amount of testosterone produced by the testes. Females – The pituitary gland controls the amount of estrogen and progesterone produced by the ovaries. Both these control when and how puberty and male/female development of the reproductive system happens. So let’s take a closer look at the mature reproductive systems of males and females.

The Female Reproductive System

Activity: List all parts of the female reproductive system you can…

Activity: Match your card’s part with your part’s function… When you find your partner, tape your cards to the board!

What are the functions of the female reproductive system? 1. Produce an egg. 2. Provide space for the egg and sperm to join…fertilization. 3. Provide the fetus with shelter and nourishment while developing. 4. Produce breast milk for baby after birth for nourishment.
