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 HHHHeart 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
