What systems of the body are essential to reproduction? Standard PG 39 Essential Question    What systems of the body are essential to reproduction? Standard B.10A - describe the interactions that occur among systems that perform the functions of regulation, nutrient absorption, reproduction, and defense from injury or illness in animals

SYSTEMS INVOLVED REPRODUCTION Reproductive Endocrine DRAW ALL OF THIS

Sexual Development Puberty is a period of rapid growth and sexual maturation during which the reproductive system becomes fully functional. When puberty ends, reproductive organs are fully developed. Puberty usually begins between the ages of 9 and 15, and usually starts one year earlier in females than in males.

Sexual Reproduction Sexual Reproduction In humans, the reproductive system produces, stores, and releases specialized sex cells known as gametes. Gametes are released to create the fusion of sperm and egg to form a zygote, the single cell from which all cells of the human body develop.

REPRODUCTIVE SYSTEM Main Parts: Male: Testes - produce sperm Female: Ovaries – produce the Eggs Uterus – where a baby develops

REPRODUCTIVE SYSTEM Main Functions: Sexual maturation (puberty) Male function: To produce & deliver sperm Female function: To produce eggs To nourish & support an embryo

ENDOCRINE SYSTEM Hormones used: Estrogen Testosterone Progesterone Female sex traits Male sex traits Progesterone Follicle-stimulating hormone Maintains uterine lining Egg & sperm development Luteinizing hormone Egg release during menstruation

What is the menstrual cycle? A developed egg is released from an ovary. The lining of the uterus thickens every month and prepares to receive an egg. If the released egg is fertilized during sex, it is implanted in the uterus and begins growing into an embryo. If the egg is not fertilized, the entire uterine lining is discharged.(shed) Controlled by feedback loops & takes an average of 28 days.

The Menstrual Cycle *Most females menstruate during the first 3-7 days of the cycle.

Copyright Pearson Prentice Hall The Menstrual Cycle Ovulation The menstrual cycle is divided into four phases. Notice the changes in hormone levels in the blood, the development of the follicle, and the changes in the uterine lining during the menstrual cycle. Copyright Pearson Prentice Hall

Diseases and Disorders of the Male Reproductive System Disease/Disorder Description Prostate cancer Most common form of cancer in men over 40; risks of developing it increase with age Prostatitis Inflammation of the prostate gland; may be acute or chronic Testicular cancer Malignant growth in one or both testicles; more common in males 15–30 years; more aggressive malignancy

Diseases and Disorders of the Female Reproductive System Disease/Disorder Description Breast cancer Second leading cause of cancer deaths in women; classified as stage 0 to 4 Cervical cancer Slow to develop; Pap smear detects abnormal cervical cells Cervicitis Inflammation of the cervix usually due to an infection Dysmenorrhea Condition with severe menstrual cramps limiting normal activities
