Chapter 1: Organ System Overview Flashcards
Integumentary system
the external covering of the body, protects deeper tissue, synthesizes vitamin D, location of cutaneous receptors; and sweat and oil glands
Skeletal system
protects and supports body organs; provides a framework the muscles use to cause movement; blood cells are formed within bones; stores minerals
Muscular system
allows manipulation of the environment, locomotion, and facial expression; maintains posture, produces heat
Nervous system
fast-acting control system of the body; responds to internal and external changes by activating appropriate muscles and glands
Endoctrine system
glands secrete hormones that regulate processes such as growth, reproduction, and metabolism by body cells
Cardiovascular system
blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc.; the heart pumps blood
Lymphatic system
picks up fluid leaked from blood vessels and returns it to blood; disposes of debris in the lymphatic stream; houses white blood cells involved in immunity
Respiratory system
keeps blood constantly supplied with oxygen and removes carbon dioxide; the gaseous exchanges occur through the walls of the air sacs of the lungs
Digestive system
breaks food down into absorbable units that enter the blood for distribution to body cells; indigestible foodstuffs are eliminated as feces
Urinary system
eliminates nitrogenous wastes from the body; regulates water, electrolyte, and acid-base balance of the blood
Reproductive system
mainly production of offspring. Testes produce sperm and male sex hormone; ducts and glands aid in delivery of cable sperm to the female reproductive tract. Ovaries produce eggs and female sex hormones; remaining structures serve as sites for fertilization and development of the fetus. Mammary glands of female breasts produce milk to nourish the newborn.
