MALE AND FEMALE REPRODUCTIVE SYSTEMS
MALE - Testosterone Seminal Vesicle Vas Deferens Prostate Gland Penis Urethra Foreskin Bulbo-Urethral Gland (Cowper’s Gland) Testicle Scrotum
MALE (cont.) Seminal Vesicle Attached to Vas Deferens Located near the base of the Bladder Secretes a fluid that mixes with the sperm to provide mobility and nourishment
MALE (cont.) Vas Deferens A tube approximately 18 inches long Carries sperm to the Seminal Vesicle
MALE (cont.) Prostate Gland Secretes the fluid that mixes with sperm to form Semen
MALE (cont.) Urethra Connects with the Bladder as well as the Vas Deferens Releases Urine OR Semen Not both simultaneously!!!!!!
MALE (cont.) Bulbo-Urethral Gland (Cowper’s Gland) Fluid Producing
MALE (cont.) Testicle (Testes) 2 Small Glands Sperm producing Gland Contains several 100 yards of coiled sperm Normal adult male produces 200 million sperm a day 500 sperm lined up would only measure 1 inch!
MALE (cont.) Scrotum Holds the Testicles Keeps Testes at a temperature slightly below the normal body temp. of 98.6 degrees As body temp. increases the Scrotum lowers (muscles relax) As body temp. decreases the Scrotum raises and the Testes pull in (muscles contract) CLOTHING CAN BE A RISK!!!!!
MALE (cont.) Epididymis Larger tube that joins the Testes A temporary storage facility for Sperm Is where Sperm will mature
MALE (cont.) Sperm Cell
MALE (cont.) Ejaculation About million Sperm in each Ejaculation One spoonful of Semen contains Million Sperm Vasectomy Cutting of the Vas Deferens Prevents the Sperm from reaching the Seminal Vesicle to mix with the fluid
MALE (cont.) Sterility Sperm is weak, malformed or unable to join the egg cell Causes: Temperature changes Exposure to certain chemicals Mumps as an Adult STD’s Testicular and Prostate Cancer (pg. 441) CANCER OF THE TESTES – AT RISK AGE-GROUP IS 15-35!!!!!! That means you guys!!!
FEMALE (cont.) Ovary Are a PAIR (2) Contains the eggs All eggs are in place at the time of birth Born with over 1 million IMMATURE egg cells
FEMALE (cont.) Fallopian Tubes Are a PAIR (2) Takes the egg to the Uterus
FEMALE (cont.) Cervix Neck of the Uterus
FEMALE (cont.) Uterus Pear shaped organ About the size of your fist Where fertilized eggs grow When the egg is released the lining of the uterus begins to thicken preparing for fertilization
FEMALE (cont.) Vagina Birth Canal A muscular, very elastic tube that serves as a passage way to the Uterus Tubal (Ectopic) Pregnancy Egg implants itself in the Fallopian Tube Egg is likely present during the middle of the Female’s monthly cycle
FEMALE (cont.) Ovulation Can occur more than once per month Menstruation Change in hormone levels can interrupt or extend the cycle Time – more or less than 28 days (average) Prolonged menstrual flow can decrease a woman’s iron level
