Ovaries, Testes and Pancreas
What are the major component organs of the Cardiovascular System?
Heart
Blood
Blood Vessels
What are the major component organs of the Lymphatic System?

What are the major component organs of the Urinary System?
Kidneys, Ureters, Bladder and the Urethra
What are the major component organs of the Reproductive System?
Males - Testes, Prostate Gland, Scrotum, Penis, Duct System (carries sperm to body exterior)
Females - Ovaries, Uterine Tubes, Uterus, Mammary Glands and Vagina
What is the function of the Integumentary System
Protects deeper organs
Excretes Salt and Urea
Aids in temperature regulation
Produces Vitamin D
What is the function of the Skeletal
Support and protect of organs
Cavities provide a site for blood cell formation
Provides a lever for muscular action
What is the function of the Muscular
to contract and extend to allow locomotion (movement)
Generates heat
What is the function of the Nervous System?
Helps maintain homeostasis via rapid transmission of electrical signals
Allows body to detect and respond to changes in internal and external environments
What is the function of the Endocrine System?
Produces messenger hormones
Promotes homeostasis
Promotes growth and development
What is the function of the Cardiovascular System?
Transport System for blood and nutrients
What is the function of the Lymphatic System?
Cleanses blood of pathogens and debris
houses lymphocytes - immune response
What is the function of the Respiratory System?
Supply oxygen to the blood removes carbon dioxide
What is the function of the Digestive System?
Breaks down food to be used by the body
undigested residue is then removed from the body as feces
What is the function of the Urinary System?
Rids the body of waste products
maintains water, electrolyte and acid base of blood
What is the function of the Reproductive System?
Male - provides germ cells (sperm) for the perpetuation of the species
Female - Provides germ cells (egg), houses the fetus until birth
mammary glands provide nutrition post natal
