Biological and Physical Sciences REPRODUCTIVE SYSTEM

Objective Identify the female and male anatomy functions of the human reproductive system in relation to Public Health.

OVERVIEW Female Anatomy/Functions Male Anatomy/Functions

Female Anatomy/Functions  Ovaries  Fallopian Tubes  The Uterus  The Vagina  External Genitalia  Mammary Glands

Female Anatomy/Functions  Ovaries  Ova  Hormone production  Fallopian Tube (Uterine Tube)  Fertilization  Fimbriae

Female Anatomy/Functions  Uterus  Main function is to house fertilized egg  Three areas  Fundus  Body  Cervix  Three layers  Perimetrium  Myometrium  Endometrium

Female Anatomy/Functions  Vagina  Passage way for delivery and menstrual flow  Organ of copulation  External Genitalia  Vulva  4 areas  Mons pubis  Labia Minora  Labia Majora  Clitoris  Mammary glands

Female Anatomy/Functions Oogenesis “The beginning of an egg” Not a continuous process. All the eggs are formed about the 7th month of fetal life. Stored until the onset of puberty Mature ovum has half the number of chromosomes (23) after meiosis.

Female Anatomy/Functions Menstrual Cycle The cyclic changes in the uterine endometrium. Cycle lasts an avg. of 28 days ( days) Divided into stages Days 1-5: MensesThick lining sloughs the uterine wall. Accompanied by bleeding for 3-7 days. Days 1-5: Menses - Thick lining sloughs the uterine wall. Accompanied by bleeding for 3-7 days. Day 6-14: Proliferation - Endometrium is repaired, glands form and blood supply increases. Day 15-28: Secretion - Blood supply increases more, glands secrete nutrients into the uterine cavity

Male Anatomy/Functions TestesEpididymis Vas Deferens Urethra Seminal Vesicles Prostate Gland Cowper's Gland SemenScrotumPenis

Male Anatomy/Functions Testes Primary reproductive organ Most sensitive to chemical, physical, and/or biological exposure Testosterone

Male Anatomy/Functions Epididymis – storage site Vas deferens – propels sperm Urethra – dual system Seminal Vesicles – 60% of fluid volume from ejaculate

Male Anatomy/Functions Prostate gland Neutralizes seminal fluid Protects sperm from acidic environment Cowper’s gland Lie under prostate gland Discharge fluid (lubricant)

Male Anatomy/Functions Semen – carries sperm Scrotum – protects testes Penis – deliver sperm

Male Anatomy/Functions Hormone production - testosterone Spermatogenesis Continuous cycle Sperm have half (23) the chromosomes First release Non-motile Incapable of fertilization. Final maturation occurs in epididymis.

Objective Identify the female and male anatomy functions of the human reproductive system in relation to Public Health.
