The reproductive system is a collection of organs and glands that work together to create new life. It is essential for the survival of a species and is responsible for the production of offspring.
Male Reproductive System
The male reproductive system consists of the testes, epididymis, vas deferens, seminal vesicles, prostate gland, and penis. The primary function of the male reproductive system is to produce and deliver sperm.
Testes: The testes are responsible for producing sperm and the hormone testosterone.
Epididymis: This is where the sperm mature and are stored.
Vas Deferens: The vas deferens is a long, muscular tube that carries sperm from the epididymis to the urethra.
Seminal Vesicles: These glands produce a fluid that mixes with sperm to form semen.
Prostate Gland: The prostate gland produces a milky fluid that helps nourish and protect the sperm.
Penis: The penis is the male organ for sexual intercourse and the passage for urine and semen.
Female Reproductive System
The female reproductive system consists of the ovaries, fallopian tubes, uterus, cervix, and vagina. The primary function of the female reproductive system is to produce eggs, receive sperm, and support the development of a fetus during pregnancy.
Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
Earth History: Recognize and explain that fossils found in layers of sedimentary rock provide evidence of changing life forms.
Recognize how different types of fossils are formed, such as petrified remains, imprints, molds and casts.
Recognize and explain that the fossil record of plants and animals describes changes in life forms over time.
