Body System Functions Flashcards
Skeletal System
Protects and supports body organs
Provides a framework the muscles use to cause movement
Blood cells are formed within bones
Bones store minerals
Integumentary System
Covering Protection Vitamin D Houses cutaneous receptors Swear and Oil glands
Muscular System
Allows manipulation of the environment, locomotion, and facial expressions. Maintains posture, and produces heat.
Nervous System
As the fast-acting control system of the body, it 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 (metabolism) by the body.
Cardiovascular System
Blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc. The heart pumps blood. only transport system
Lymphatic/Immunity System
- Picks up fluid leaked from blood vessels and returns it to the blood.* Disposes of debris in the lymphatic system. Houses white blood cells (lymphocytes) involved in immunity. The immune response mounts the attack against foreign substances within the body.
- main function
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 down food 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 (as a whole)
Overall function is production of offspring.
Male Reproductive System
Testes produce sperm and male sex hormone, and male ducts and glands aid in delivery of sperm to the female reproductive tract.
Female Reproductive System
Ovaries produce eggs and female sex hormones. The remaining female structures serve as sites for fertilization and development of the fetus. Mammary glands of female breasts produce milk to nourish the newborn.
