Cardiovascular System & the Heart

The Cardiovascular System SN p. 125  Links all parts of your body  Consists of heart, blood vessels, and blood  Main functions  Delivering needed materials to all cells  Oxygen, food  Removes waste products from cells  Carbon dioxide  Fighting Disease – transports cells that attack disease causing microorganisms

Blood  Blood is a complex tissue that is made up of:

Blood Vessels  Arteries – carry blood rich with oxygen and nutrients away from the heart  Capillaries – smallest blood vessel with thin walls, exchange of materials between blood and body cells  Veins – carry oxygen-poor cells back to the heart

Heart Activity SN p. 125  Click the clothespin together as many times as you can for 2 minutes.  Collect your personal data, both quantitative and qualitative Trial #QuantitativeQualitative Trial 1 Trial 2 Trial 3

Heart SN p. 131  Left Atrium  Left Ventricle  Vena Cava  Pulmonary Artery  Right Atrium  Right Ventricle  Aorta  Pulmonary Vein Body/Sci-Media/Animation/Label-the-heart

Two Loop System  The heart is at the center of 2 loops  First loop, blood travels from the heart to the lungs and back  Second loop, blood travels throughout the body and back  Heart is 2 pumps – right side pumps blood to lungs, left side pumps blood to the rest of the body

Loop one: To the Lungs and Back  Blood entering right atrium is oxygen poor, but rich in CO2; blood in dark red  Passes through valve into right ventricle  Ventricle pumps blood out into the pulmonary artery to the lungs  Large blood vessels branch into smaller ones to capillaries  Blood cells drop off waste CO2(exhaled) and pick up O2 (inhaled)  Blood leaves lungs oxygen-rich ( bright red) and goes back to the left atrium

Loop Two: To the Body and Back  Left atrium fills with oxygen rich blood  Flows through a valve to left ventricle  Left ventricle pumps blood out of the heart through the aorta  Passes through branching arteries to capillaries, where oxygen is delivered to cells and CO2 is picked up  Blood that is low in oxygen returns to heart through veins to the right atrium
