Question
Chapter 30, Problem 3PIT
Summary Introduction
To add:
The terms placenta, follicle, polar body, gonad, gametes, meiosis and mitosis in the given concept map.
Introduction:
In an anatomical aspect, the reproductive systems include ovaries, uterus, and breasts in females, testes, and penis in males. The hormones such as FSH, GnRH, LH, and estrogen are important in males as well as in females. The other sex hormones like progesterone and testosterone are specified as primary sex hormones in females and males, respectively.
