THE CIRCULATORY SYSTEM • Takes 60 seconds for a blood cell to make a complete circuit of the body • 5. 6 liters of blood being pumped at a time • Your heart will beat 100, 000 times today = 2 liters • 35 million beats a year • Aorta- diameter of garden house, capillaries as thin as a hair = 1 liter

WHAT’S IN YOUR BLOOD? • Plasma • • Liquid part of the blood 90% water • White Blood Cells • • Fight infection • Engulf bacteria cells Red Blood Cells • Most common blood cells • • Hemoglobin transported • Carries oxygen Platelets • • Cell fragments Helps clot blood

BLOOD VESSELS • Artery “away” • Blood pushed away from heart • Blood vessel where a pulse can be felt • Delivers oxygen-rich blood to capillaries • High pressure • Capillaries • Smallest blood vessel • Exchange materials, from blood to tissues and tissues to blood O 2, CO 2, waster, nutrients • Veins • Contains valves • • Brings wastes to the heart and lungs Low pressure • Varicose Veins valves no longer work

YOU’VE GOTTA HAVE HEART • Heart failure is the leading cause of death in men and women • ~ 800, 000 Americans a year of a heart attack • ~ 500, 000 Americans who have already had a heart attack have another one every year • Heart disease costs in America ~ $108. 9 billion

NODES • Natural pacemakers • Sinoatrial Node (SV node or SA node) • Cardiac muscle mass on top of right atrium • Primary generator regular electrical impulses of the heart • Controls pulse, sends it to AV node • Atrioventricular Node (AV node) • Secondary response, controls contraction • Delays signal, prevents simultaneous contraction • Artificial Pacemakers • Atrial Fibrillation • Electrical signals and impulses occurring in places other than the nodes • Prevents the right atrium from filling up with blood, body is deprived of blood.

TYPES OF CIRCULATION • Two types • Systemic (greater) Circulation • Pulmonary (lesser) Circulation • Systemic • Part of circulation that carries oxygenated blood away from heart to the rest of the body. • Which side of the heart pushes the blood out? • Which vessel carries oxygenated blood away?
![TYPES OF CIRCULATION • Pulmonary circulation • Blood flow between heart and lungs. • TYPES OF CIRCULATION • Pulmonary circulation • Blood flow between heart and lungs. •](http://slidetodoc.com/presentation_image_h/eeb9d553a66986483ae2075050264092/image-22.jpg)
TYPES OF CIRCULATION • Pulmonary circulation • Blood flow between heart and lungs. • Primary job is to exchange O 2 and CO 2 • In this way, it keeps systemic circulation on track
