  1. The Reproductive Systems: • The main functions of the reproductive systems are to make egg and sperm cells which will combine to make a zygote (offspring) • Gamete = sex cell Male Reproduction • The function of the male reproductive system is to produce and deliver sperm. • Sperm are made in the testes through the process of meiosis. • In human males, sperm are haploid & have 23 chromosomes

  2. testes: 2 walnut sized organs that make sperm • scrotum: 2 pouches that each contain one testis outside the body. • vas deferens – tube that sperm travel through when they are released from each testis. • urethra – tube that connects the 2 vas deferens and travels through the penis. • Both sperm & urine travel through the urethra

  3. THREE FUNCTIONS OF THE FEMALE REPRODUCTIVE SYSTEM • To produce eggs • To receive sperm • Provide an environment that a baby can develop in

  4. How are eggs produced & released in females? • ovaries:2 ovaries are where eggs are made through meiosis. 1 egg is released each month called ovulation • fallopian tube: tube the egg travels through one it is released from the ovary. (also calledoviduct)there are 2 fallopian tubes. • uterus: fist sized organ where an embryo grows. • vagina: passageway to the outside of the body - baby is born through this passageway and sperm are deposited here

  5. Your Endocrine System - The endocrine system is a collection of special organs in the body that produce hormones and send them directly in to the blood stream. • Organs of the endocrine System: (Called Glands) • pituitary – regulates growth (located in the brain) • thyroid – regulates metabolism (found in the neck) • adrenal – regulate hormone that helps humans deal with stress (adrenaline) (located along the kidneys) • ovaries and testes – regulate hormones involved in the expression of sexual characteristics
