Transcript of "Cardiovascular System"

  1. 1. Cardiovascular System Weighing in at 10 ounces, the blood-filled muscle called the heart has become the universal symbol of love. The Greeks believed the heart was the seat of the spirit, the Chinese associated it with the center for happiness and the Egyptians thought the emotions and intellect arose from the heart. No one is sure the exact origin of the love association, however. One idea is that the heart got its "love mark" in the ancient Greek city of Cyrene, now in modern-day Libya. The colony was known for a plant called Silphium, with heart-shaped seed pods. Silphium had medicinal properties, and possibly also was used as an herbal contraceptive.hsc 1531 medical terminology | FSCJ | professor: michael l. whtichurch, MHS
  2. 2. Heart Facts  System is over 60,000 miles long  Adult heart pumps 5 quarts of blood each minute  2,000 gallons each day  Beats about 100,000 times each day  Average 70 year life span = 2.5 billion beats  Adult woman heart = 8 oz.  Adult man = 10 oz  Blood is 78 % water  20 seconds to completely circulate the vascular system http://my.clevelandclinic.org/heart/heartworks/heartfacts.aspx

  22. 22. Heart Chambers  Divided into four chambers  Two atria  Two ventricles  Heart is divided into right and left sides by a wall called the septum
  23. 23. Atria  Left and right upper chambers  Receiving chambers  Blood returns to atria in veins  Superior and Inferior vena cava  Pulmonary veins
  24. 24. Ventricles  Left and right lower chambers  Pumping chambers  Thick myocardium  Blood exits ventricles into arteries  Aorta  Pulmonary artery

  27. 27. Heart Chambers Animation
  28. 28. Heart Valves  Four valves in heart  Tricuspid  Pulmonary  Mitral  Aortic
  29. 29. Heart Valves  Act as restraining gates to control direction of blood flow  Found at entrance and exit to ventricles  Allow blood to flow only in forward direction by blocking it from returning to previous chamber
  30. 30. Tricuspid Valve  An atrioventricular valve  Between right atrium and ventricle  Prevents blood in ventricle from flowing back into atrium
  31. 31. Tricuspid Valve  Has 3 leaflets or cusps

  49. 49. Conduction System of the Heart  Autonomic nervous system controls heart rate  Therefore, no voluntary control over heart  Special heart tissue conducts electrical impulses  Stimulate different chambers to contract in correct order
  50. 50. Path of the Conduction System 1. Sinoatrial (SA) node, or pacemaker, is where electrical impulse begins  From SA node a wave of electricity travels through atria  Causing them to contract, or go into systole
  51. 51. Path of the Conduction System 2. Next, atrioventricular node (AV) is stimulated 3. This node transfers stimulation wave to bundle of His
  52. 52. Path of the Conduction System4. Electrical wave travels down bundle branches within interventricular septum5. Finally, Purkinje fibers in ventricular myocardium are stimulated  Results in ventricular systole Figure 5.7
  53. 53. Systole and Diastole  Heart chambers alternate between:  Relaxing to fill  Contracting to push blood forward  Relaxation phase is diastole  Contraction phase is systole
