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 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 THANKS FOR WATCHING!!
