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

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
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
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
Copyright © 2006 Thomson Delmar Learning The Penis The penis is the male sex organ that carries reproductive and urinary products out of the body
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
The Ovaries The ovaries are a small pair of organs located in the caudal abdomen The ovaries produce estrogen, progesterone, and ova (eggs)
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
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
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
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
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
