Body Systems Flashcards
Forms the external body covering, and protects deeper tissues from injury.
Integumentary System
Protects and supports body organs, and provides a framework the muscles use to cause movement.
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
Lymphatic 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.
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.
Reproductive System
