Understanding the Reproductive System: Key Vocabulary and Concepts

This guide provides essential vocabulary and concepts related to the human reproductive system. It covers the processes of fertilization, the roles of eggs and sperm, and the development of the zygote. The male reproductive system, including the testes, testosterone, and semen, is explained, as well as the female reproductive system, focusing on ovaries, estrogen, and the menstrual cycle. Understanding these components is crucial for grasping how sexual reproduction occurs and the hormonal influences involved in human development.

  1. The Reproductive system

  2. Vocabulary • Fertilization • Egg • Sperm • Zygote • Testes • Testosterone • Estrogen • Ovary

  3. Vocabulary Continued • Scrotum • Semen • Penis • Vagina • Menstruation • ovulation • Menstruation Cycle • Fallopian Tube

  4. Sexual Reproduction • The joining of egg and sperm is called fertilization. • Egg is a female sex cell. • Sperm is the male sex cell. • Both are made during meiosis. • Fertilized egg is called a zygote.

  5. Male Reproductive System • The testes, an endocrine gland which releases the hormone testosterone, is where sperm are produced. • Located in scrotum to minimize heat. • Testosterone controls male development. • Sperm has a head that contains chromosomes. • Sperm mixes with semen to provide an environment to swim. Semen also provides nutrients for sperm. • Semen travel down urethra which travel through the penis. Muscle contraction prevent urine and semen from mixing.

  6. Female Reproductive System • Specialized to produce eggs (in ovaries) and nourish a developing baby until birth. Produces estrogen and other hormones for development. • Each month one ovary releases a mature egg (menstruation) down the fallopian tube. Fertilization, the joining of egg and sperm, occurs in the fallopian tube. • Egg travels to uterus, a hollow, muscular organ where egg attaches. If unfertilized, egg breaks down (menstruation). • Vagina or birth canal is where the baby leaves mother during childbirth.

  7. Menstrual Cycle
