Heart • Fist sized bag consisting of two pumps • One for pulmonary • One for systemic
Blood Vessels • 90,000 Miles of blood vessels networked together to make up the circulatory system
Function of the Circulatory System • Maintain an internal environment • Nourish all of the cells of the body
Heart • Special type of muscle • myocardium
Pulmonary Heart System Lungs • Left Side • Receives oxygen rich blood from the lungs • Pumps oxygen rich blood to the body • Oxygen is passed to body tissue and blood returns to the heart • Systemic System Right Lung Left Lung
Systemic System of the Heart • Right Side • Receives oxygen deficient blood into the hearts atrium • Right Atrium is known as the hearts pacemaker • Passes to the ventricle • Heart pumps the blood to the lungs • Blood returns to the left side of the heart
One-way Valves • Located at the exit of each chamber • Guarantees that blood flows in one direction • Prevents what is known as backflow
Right Atrium • SA Node is the hearts pacemaker • The Synarthrodial node controls the heart rate
Blood • Delivers oxygen, hormones, and nutrients to the cells and caries away waste product • Red blood cells contain hemoglobin rich in iron for oxygen to attach too • YouTube - Oxygen Transport • Plasma is 92% water, it also contains salts, proteins,red blood cells, white blood cells and plateletsYouTube - How the Body Works : Blood Clotting • Platelets the bloods clotting system
White Blood cells • Protect against and fights infection • Form antibodies making you immune to the infection • Production increases when there is an infection in the body
Major groups of vessels in the body • Arteries • Veins • Capillaries
Blood vessels • Arteries • Arterioles • Capillaries • Veinules • veins
Coronary vessels • Supply the myocardium with oxygen rich blood • These vessels branch directly from the aorta • http://www.youtube.com/watch?v=kUQe6I6vv74 • YouTube - PreOp® Coronary Artery Bypass CABG) Patient Education
Blood Pressure • The force of blood being applied to the main arteries measured in mm of mercury • Systolic (top Number) is arterial pressure at it’s highest point • Diastolic (bottom Number) measures the pressure on the arterial walls at its lowest or resting point
Arteriosclerosis Plaque build up in the arteries Treatment of angioplasty or stint http://www.youtube.com/watch?v=S9AqBd4RExk&feature=endscreen&NR=1
Lymphatic and Respiratory Systems • Work to maintain fluid balance and fight infection • White blood cells make you immune to certain diseases: chicken pox, mumps, and measles.
Lymphatic System • Drains tissue fluid back into the bloodstream • Fights infections • Movement of the muscles helps circulate the lymph fluid (proteins, fats and white blood cells)
B Cells • Enlarge and multiply produce antibodies that destroy invading pathogens
T Cells • Attach to abnormal cells and emit toxins through a needle like projection to kill abnormal cells
Anemia- iron deficiency in a diet. Congenital Heart Disease- hole in the chamber of the heart, malfunction of valves. Heart Murmur- malfunctioning valve Leukemia- prevents bone marrow from producing red blood platelets and white blood cells. Hemophilia- blood is slow to clot. Varicose Veins- swollen and enlarged veins. Circulatory Conditions
