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 cellMale 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 eggs2. To receive sperm3. 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

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
