STRUCTURAL AND FUNCTIONAL ORGANIZATION Flashcards
Forms the external body covering, and protects deeper tissues from injury. Synthesizes vitamin D, and houses cutaneous (pain, pressure, etc.) receptors, and sweat and oil glands.
Integumentary System
Protects and supports body organs, and provides a framework the muscles use to cause movement. Blood cells are formed within bones. Bones store minerals.
Skeletal System
Allows manipulation of the environment, locomotion, and facial expression. Maintains posture, and produces heat.
Muscular System
As the fast-acting control system of the body, it responds to internal and external changes by activating appropriate muscles and glands.
Nervous System
Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells.
Endocrine System
Blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc. The heart pumps blood.
Cardiovascular System
Picks up fluid leaked from blood vessels and returns it to blood. Disposes of debris in the lymphatic stream. Houses white blood cells (lymphocytes) involved in immunity. The immune response mounts the attack against foreign substances within the body
Lymphatic System/Immunity
Keeps blood constantly supplied with oxygen and removes carbon dioxide. These exchanges occur through the walls of the air sacs of the lungs.
Respiratory System
Breaks down food into absorbable units that enter the blood for distribution to body cells. Indigestible foodstuffs are eliminated as feces.
Digestive System
Eliminates nitrogenous wastes from the body. Regulates water, electrolyte, and acid-base balance of the blood
Urinary System
Overall function is production of offspring. and male ducts and glands aid in delivery produce eggs and female sex hormones. fertilization and development of the fetus. milk to nourish the newborn.
Male Reproductive System
Testes produce sperm and male sex hormone, of sperm to the female reproductive tract. Ovaries The remaining female structures serve as sites for Mammary glands of female breasts produce
Female Reproductive System
