Descripción: Neil Young - Heart Of Gold para piano
Inside is serous pericardium - double layer around heart
Filled with pericardial fluid - reduces friction during beat.
Position of the Heart
Functions of the Heart 1.
Generates blood pressure
2.
Routing blood pulmonary, systemic circulation
1.
One way blood flow
2.
Regulates blood supply
Chambers of the Heart
4 chambers
2 upper chambers = Atria
Between is interatrial septum
2 lower chambers = ventricles
Between is interventricular septum
LV – thicker wall - contracts more forcefully - generates greater BP
Structure of the Heart
Structure of the Heart
Structure of the Heart
Great Vessels Of Heart-Right
Superior & inferior Vena Cavae Delivers deoxygenated blood to R. atrium from body Coronary sinus drains heart muscle veins R. Atrium R. Ventricle pumps through Pulmonary Trunk R & L pulmonary arteries lungs
Great Vessels Of Heart-Left
Pulmonary Veins from lungs
oxygenated blood
L.
atrium Left ventricle
ascending
aorta body
Valves
Designed to prevent back flow in response to pressure changes Atrioventricular (AV) valves
Between atria and ventricles
Right = tricuspid valve (3 cusps) Left = bicuspid or mitral valve Semilunar valves near origin of aorta & pulmonary trunk Aortic & pulmonary valves respectively
Atrioventricular Valves: Bicuspid Valves
Blood Flow Through Heart
Blood Flow
Exercise and the Heart
Aerobic exercise (longer than 20 min) strengthens cardiovascular system Atherosclerotic plaque-depots of chole, lipid
Coronary thrombosis
Infarct-dead heart
Blood Pressure
Device used: sphygmomanometer
Inflate cuff to raise pressure > systolic BP
First sound indicates systolic BP
Lower pressure further until sound become faint
Briefly stop blood flow there
Lower pressure in cuff until flow just starts
Usually on brachial artery
Diastolic BP
Normal BP values <120 mm Hg for systolic and < 80 mm Hg for diastolic
