Unit 1 Lecture Quiz Flashcards
Integumentary System
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.
Skeletal 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.
Muscular System
Allows manipulation of the environment, locomotion, and facial expression. 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 body cells.
Cardiovascular System
Blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc. The heart pumps blood.
Lymphatic System/ Immunity
Picks up fluid leaked from blood vessels and returns it to blood. Disposes of debris in lymphatic stream. Houses white blood cells (lymphocytes) involved in immunity. The immune response mounts the attack against foreign substances within the body.
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
overall function is production of offspring. Tested produce sperm and male sex hormone, and male ducts and glands aid in delivery of sperm to the female reproductive tract. 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.
