Orderly movement through a circuit. 2. Flow. - Merriam Webster’s Dictionary The Constituents of the Cardiovascular System  Heart Structure: Cone shaped Lies between the lungs Rough size estimate, close to a fist Made up of four chambers: two upper chamber Atrium (plural-Atria) two lower chamber (Ventricles) Septum, a muscle that separates left and right side of the heart  Heart Function Circulates (pumps) blood and essential nutrients and minerals all over the body Keeps the blood pressure in check  Blood – The Basics Considered as a Fluid Tissue River of Life Acts as multiple transportation medium in the body Components: RBC WBC Plasma Platelets  Red Blood Cell - Erythrocyte Function: Oxygen and Carbon Dioxide carrier to and from the lungs  White Blood Cells - Leukocytes Function: Body’s internal defense and immunity unit Types of Leukocytes  Platelets - Thrombocytes Function: Bleeding control  Vein - Micrograph Function: Moves blood that carries waste materials toward the heart.  Vein - Illustration In (scientific) illustrations, they are usually blue in color  Artery- Micrograph Function: Moves oxygenated blood away from the heart  Artery - Illustration In (scientific) illustrations, they are usually red in color Sherlocks!  Capillaries The smallest of blood vessels, allows diffusion of oxygen and nutrients, carrying of carbon dioxide and waste materials in an organ level manner.  Body Circulation Simplified Process of Blood Circulation  Detailed Illustration of Blood Circulation  Right Steps 7-10 Ventricle SYSTEMIC Pulmonary Right Atrium Arteries CIRCUIT 1 10 2 Superior and Lung BLOOD Inferior Vena Capillaries Cava 9 3 CIRCULATION 8 4 Whole Body summary Pulmonary Veins 7 5 6 Aorta Left Atrium Steps 1-6 PULMONARY CIRCUIT Left Ventricle END OF SLIDE On to the next!
