1. StructureFunction Seminiferous tubules Sperm produced here. Interstitial cells Produces testosterone directly into the blood stream Prostate gland Produces a fluid which is part of semen, containing enzymes which controls viscosity of fluid for mobility. Seminal vesicles Produces a fluid which allows Sperm Male gamete with 23 chromosomes produced by meiosis in seminferous tubules in testes. Sperm duct Links the testes (sperm produced) to the urethra where it is deposited. Penis Inserted into the vagina during sexual intercourse. Accessory gland Include seminar vesicles and prostate gland which produce fluids which makes up semen with sperm. Male and Female Reproductive Organs

2. Male Reproductive Organs Summary – Copy and complete The _________ of the human male produce sperm and the hormone ______. The _____ vesicles secretes a liquid containing _________ (sugar) and prostaglandins which stimulate ______ of the female reproductive tract. The ________ gland makes lubricating liquid which ensure mobility of the sperm by an _______ altering viscosity.

3. Male Reproductive Organs Summary – Copy and complete The _testes___ of the human male produce sperm and the hormone _testosterone_____. The _seminal_ vesicles secretes a liquid containing _fructose_ (sugar) and prostaglandins which stimulate _contractions_ of the female reproductive tract. The _prostate__ gland makes lubricating liquid which ensure mobility of the sperm by an _enzyme__ altering viscosity.

4. Learning Outcomes Identify the cells and organs that produced the gametes Examine the structure of testes and ovaries and their functions in the production gametes Complete the word glossary and the diagrams

5. Oviduct / Fallopian tube Fertilisation may occur Ovary Produces eggs / ova Vagina The penis is inserted during sexual reproduction Uterus / Womb Where the baby grows Uterus lining Lining of the womb, where favourable conditions for implantation of embryo Cervix The neck of the uterus which connects to the vagina. Female Reproductive System

6. Developing Egg Eggs are formed by meiosis in the ovaries. Each ovum (egg) is surrounded by a developing (Graafian) follicle which secretes oestrogen (a hormone) and protects ovum. After ovulation (release of the egg), the (Graafian) follicle develops into a corpus luteum which secretes the hormone progesterone.

10. StructureFunction Ova Female gamete, containing 23 chromosomes (haploid) Graafian follicle Surrounds ovum, produces hormone oestrogen Corpus luteum After ovulation the graafian follicle develops into this structure which produces progesterone Ovary Site for ovum production by meiosis Oviduct Location where fertilisation may occur, linking ovary to uterus Uterus Where embryo and baby will develop Cervix Opening at the bottom of the uterus linking vagina to uterus Vagina The penis is inserted during sexual reproduction Male and Female Reproductive Organs

11. Review 2 hormones produced by the female reproductive system and the structures that produce them? 3 structures found in the ovary 1 location for fertilisation
