1. Reproductive System

2. The Reproductive System  The reproductive system is responsible for the act of producing offspring  needs both male and female organs  The reproductive organs are called genitals  genit/o refers to the organs of reproduction

3. Copyright © 2006 Thomson Delmar Learning The Male Reproductive System  The male reproductive system is responsible for the production and delivery of sperm to the egg to create life  The structures of the male reproductive system include the scrotum, testes, epididymis, vas deferens, accessory sex glands, urethra, and penis

4. Copyright © 2006 Thomson Delmar Learning The Scrotum  The scrotum or scrotal sac is the external pouch that encloses and supports the testes

5. Copyright © 2006 Thomson Delmar Learning The Testes  The testes or testicles are the male sex glands that produce spermatozoa  The combining forms for the testes are orch/o, orchi/o, orchid/o, test/o, and testicul/o

6. Copyright © 2006 Thomson Delmar Learning The Epididymis  The epididymis is the tube at the upper part of each testis that secretes part of the semen, stores semen before ejaculation, and provides a passageway for sperm  Made up of a head, tail, and body

7. Copyright © 2006 Thomson Delmar Learning The Ductus Deferens  The ductus deferens is the tube connected to the epididymis that carries sperm into the pelvic region toward the urethra

9. Copyright © 2006 Thomson Delmar Learning The Accessory Sex Glands  The accessory sex glands include the seminal vesicles, prostate gland, and bulbourethral gland  Seminal vesicles secrete thick substance that nourishes sperm  The prostate gland secretes a thick fluid that aids in the motility of sperm  The bulbourethral glands secrete a thick mucus that acts as a lubricant for sperm  Not all glands are present in all species

10. The Urethra  The urethra is a singular tube passing through the penis to the outside of the body that serves both reproductive and urinary systems

11. Copyright © 2006 Thomson Delmar Learning The Penis  The penis is the male sex organ that carries reproductive and urinary products out of the body

12. The Female Reproductive System  The female reproductive system is responsible for the creation and support of new life  The structures of the female reproductive system include the ovaries, uterine tubes, uterus, cervix, vagina, vulva, and mammary glands

13. The Ovaries  The ovaries are a small pair of organs located in the caudal abdomen  The ovaries produce estrogen, progesterone, and ova (eggs)

14. The Uterine Tubes  The uterine tubes are paired tubes that extend from the cranial portion of the uterus to the ovary (although they are not attached to the ovary)  The uterine tubes carry ova from the ovary to the uterus and transport sperm

15. Copyright © 2006 Thomson Delmar Learning The Uterus  The uterus is a thick-walled, hollow organ with muscular walls and a mucous membrane lining  The combining forms for the uterus are hyster/o, metr/o, metri/o, and uter/o

16. The Cervix  The cervix is the caudal continuation of the uterus and the cranial continuation of the vagina  The cervix prevents foreign substances from entering the uterus  The combining form for the cervix is cervic/o

17. The Vagina  The vagina is the muscular tube lined with mucosa that extends from the cervix to outside the body  The vagina accepts the penis during copulation

18. The Vulva  The vulva is the external opening to the urogenital tract that leads into the vagina  The perineum is the region between the vaginal orifice and anus in females  The vulva consists of the vaginal orifice, vestibular glands, clitoris, hymen, and urethral orifice
