3.8: Understand How the Structure of the Male and Female Reproductive Systems are Adapted for their Functions

MALE REPRODUCTIVE SYSTEM: All organs responsible for the production of Sperm (the male gamete)

Diagram:              

Diagram showing structure of Male Reproductive System

ADAPTATION:

STRUCTURE	EXPLANATION
BLADDER	Muscular sac that stores Urine to expel it from body through Urethra via excretion
SEX GLAND	Gland that secretes fluid containing Nutrients (Fructose) and Mucus with Sperm cells to form Semen
SPERM DUCT	Long tube which conducts Sperm from Testes to be mixed with fluids in sex gland (which connects to the Urethra) during ejaculation
URETHRA	Tube inside Penis that conducts Sperm/Semen from Sex gland to outside of body via Penis (also convey Urine)
TESTIS	Two oval-shaped organs held outside the body by Scrotum (to maintain optimum temperature below core body temeprature) to synthesize Sperm and Tetosterone
PENIS	Passes Urine Out of the Body from the Bladder and Allows Semen to Pass into the Vagina of a Woman during Sexual Intercourse

FEMALE REPRODUCTIVE SYSTEM: All organs responsible for the production of Egg cell (the female gamete)

ADAPTATION:

STRUCTURE	EXPLANATION
BLADDER	Muscular sac that stores Urine to expel it from body through Urethra via excretion
OVIDUCT	Tube lined with ciliated cells to brush released Ovum from Ovary to Uterus for fertilisation
OVARY	Tissue where Egg cell matures prior to Ovulation, and responsible for Estrogen and Progesterone secretion
UTERUS	Organ with thick muscular walls with soft lining where fertilised Egg cell will be implanted to develop into Fetus
CERVIX	Ring of muscle that closes to protect developing Fetus and opens to form birth canal
URETHRA	Tube that passes Urine out of the body from the Bladder via excretion
VAGINA	Muscular passage leading to Uterus by which penis can enter during sexual intercourse to deliver sperm
