Anatomy Male Reproductive System
The Male Reproductive System • Male has reproductive organs that are both inside and outside the pelvis. • The testicles • The duct system • The accessory glands • The penis
THE REPRODUCTIVE SYSTEM • The Male Reproductive System • Scrotum • contains testes – hangs outside body to regulate temperature • smooth muscle can raise or lower it
sperm develops here • Testicles • Testosterone produce (male hormone)
The Duct System • Epididymis • Mature & storage of sperm • located above and behind the testicle
Ductus (vas) deferens • carries sperm from the epididymis to the urethra
The penis • Made up of two parts • The shaft (main part of penis) • The glans (tip of the penis) • At the end of the glans is a small slit or opening, which is where semen and urine exit the body.
What does the Male Reproductive System Do? • The male sex organs work together to produce and release semen into the reproductive system of the female during sexual intercourse. • Produces sex hormones, which help a boy develop into a sexually mature man during puberty.
How do sperm travel • They develop in the testicles • Move to the vas deferens • The seminal vesicles and prostate gland produce a whitish fluid called seminal fluid • Mixes with sperm-form semen • The erect penis forces semen out through the duct system and urethra • Each time a man ejaculates, it can contain up to 500 million sperm.
The Female Reproductive System • Located entirely in the pelvis • Vulva- opening to the vagina and other reproductive organs located inside the body. • Internal Organs • Vagina • Uterus • Fallopian Tubes • Ovaries • Breasts and Mammary Glands
Ovaries • Small pair of glands (size of almonds) • Produce female sex hormones-estrogen and progesterone • Ova (eggs)
Fallopian Tubes • Pair of muscular tubes that extend from the left and right upper corners of the uterus to the edge of the ovaries. • Eggs are carried to uterus
Uterus • Hollow, muscular, pear-shaped organ • Connected to fallopian tubes • Connected to vagina via cervix • Provides support to the embryo during early development
Vagina • Elastic, muscular tube that connects the cervix of the uterus to exterior of the body
The 3 Purposes of the Vagina • Penis is inserted during sexual intercourse • Pathway that a baby takes out of a woman’s body during childbirth, called the birth canal. • It provides the route for the menstrual blood (period) to leave the body from the uterus.
Breasts and Mammary Glands • The breasts are specialized organ- contain mammary glands, milk ducts, and adipose tissue • The mammary glands-produce milk to feed infants
