The Circulatory System what does it mean & how it applies to you

FUNCTIONS  1. To pump/send/deliver blood carrying oxygen and nutrients to the body  2. To take away wastes (CO2 and other by products)

Components HHHHeart Muscle that pumps blood throughout the body. Blood Vessels Arteries - carries oxygenated blood (red) Veins - carry oxygen depleted blood Capillaries-small vessles that allow the exchange of oxygen and wastes to cells

BLOOD  Red Blood Cells  White Blood Cells-fight infection and disease  Platelets-help blood clot  Plasma-liquid part of blood  Hemoglobin-iron in red blood cells that binds and carries oxygen

Process  The blood vessels are a closed system, arteries… capillaries… veins; the heart pumps with every beat it pushs blood through this system, sending blood to ever cell in the body.

Problems  Cardiovascular disease-plaque or fatty deposits build up inside ateries or veins, closing down those vessels and blocking blood from the heart  Anemia-not enough iron in the blood, therefore blood does not carry enough oxygen-easily tired and winded
