Reproductive Systems and Endocrine System Overview
Learn about the functions of the male and female reproductive systems, including the production of gametes, egg release, and hormone regulation. Discover the role of the endocrine system in hormone production and its impact on growth, metabolism, stress response, and sexual characteristics.

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
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
THREE FUNCTIONS OF THE FEMALE REPRODUCTIVE SYSTEM 1. To produce eggs 2. To receive sperm 3. Provide an environment that a baby can develop in
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 called oviduct) 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 Eggs1
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
