Male Reproductive System Ureter Rectum Bladder Seminal Vesicle Prostate Gland Vas Deferens Cowper’s Gland Penis Epididymis Urethra Testicle Scrotum
Male Reproductive System Vas Deferens
Male Reproductive System Name Description Function Scrotum - sac outside the body - lies behind the penis -holds the testes -regulates testicle temperature to insure proper sperm production Testes (Testicles) -small oval shaped organ located inside the scrotum -produces male hormones (testosterone) and sperm Sperm -resembles a tadpole in shape -propelled by tails -average lifespan – 72 hrs -male reproductive cell -Fertilizes ovum to form baby -1/4 billion sperm, only one fertilizes, rest die Vas Deferens -muscular tube which connects the testes to the prostate gland -moves the sperm from the epididymus (testes) to ejaculatory duct Prostate Gland -surrounds the urethra at the neck of the bladder and contains the ejaculatory duct -produces fluid which makes up seminal fluid -aids in ejaculation -close off bladder so sperm and urine do not mix Semen -whitish fluid that carries the sperm during ejaculation -Medium for sperm to move -lubricant in sexual intercourse Urethra Muscular tube extending form the bladder through the prostate gland and penis -carries both urine and sperm Penis -organ above testes -large and erect when sexually stimulated -made of erectile tissues and blood -contains the urethra for passage of urine and sperm -organ used to enter and to deposit sperm in the vagina Seminal Vesicle - pair of hollow like glands lying next to the bladder, joining the vas deferens and prostate gland -production of a substance important to the survival of the sperm
Injuries/Caring • Hernia • Common, portion of the intestines pushes through the groin area • Testicular Injury • Direct contact to the testicles • Testicles can also twist cause lack of blood supply to testicles • Steroid Use • Testicles can atrophy and shrink • STI’s • Talk about this later • Testicular Cancer • Prostate Cancer
Testicular Cancer • One of the most common forms of cancer for men under the age of 40 • Cells in the testicles divide abnormally to form a tumor • If detected early, can be cured • Testicular self examination
Prostate Cancer • 20,000 Canadian men are diagnosed each year • 1 in 7 men will develop prostate cancer • Prostate exam critical in men over 40 • Symptoms • Painful urination • Blood in urine • Pain in lower back, pelvic area • Painful ejaculation
Female Reproductive System Fallopian Tube Ovary Uterus Cervix Vagina
Female Reproductive System Endometrium(Lining of Uterus)
Name Description Function Ovum -mature egg ready for fertilization -oval shaped, size of a pinhead -female sex cell -grows into fetus when fertilized by sperm Ovaries -a pair of oval shaped organs located at the end of the fallopian tubes, but not attached -production and storage of ova -production of ovarian hormones (estrogen and progesterone) Fallopian Tubes -thin tubes -walls are muscular and line with fine hairs -conducts the ovum form the ovary to the uterus -place where fertilization occurs Uterus -connected to the vagina -hollow muscular organ -shaped like an upside down pear -located near bladder and large intestine -endometrium grows in preparation for implantation of zygote, and growth of baby -no fertilization, lining is shed – menstruation Vagina -3 to 4 inch muscular canal located between urinary opening and anus -For sexual intercourse -receives sperm -birth canal Cervix -neck of uterus -muscular -holds baby in the uterus -expansion and contraction during labor and menstruation cycle Female Reproductive System
