Organ System

• Integumentary system. Forms the external body covering; protects deeper tissue from injury.
• Skeletal system. Protects and supports body organs; provides a framework the muscles use to cause movement.
• 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.
• Endocrine system. Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use by body cells.
• Cardiovascular system. Blood vessels transport blood, which carries oxygen, nutrients, hormones, carbon dioxide, 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 applied with oxygen and remove carbon dioxide; the gaseous exchanges occur through the walls of the air sacs of the lungs.
• Digestive system. Breaks food down into absorbable nutrients that enter the blood for distribution to body cells; indigestible foodstuffs are eliminated as feces.
• Urinary system. Eliminates nitrogen-containing wastes from the body; regulates water. electrolytes, and acid-base balance of the blood.
• Reproductive system. Overall function of this system is to produce offsprings.
