THE MALE REPRODUCTIVE SYSTEM Male has reproductive organs

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

• Testicles • sperm develops here • 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.

ANATOMY FEMALE REPRODUCTIVE SYSTEM

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

THE FEMALE REPRODUCTIVE SYSTEM

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, pearshaped 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
