  1. Anatomy and Physiology Basics Cardiovascular System

  2. Overview of Heart’s primary job • http://www.nlm.nih.gov/medlineplus/ency/anatomyvideos/000012.htm

  3. What do ARTERIES carry? • blood • Oxygen-poor blood • Oxygen-rich blood

  4. True or False? When the heart pumps oxygen- rich blood, it provides ITSELF with oxygen-rich blood. TRUE!

  5. What do VEINS carry? • blood • Oxygen-poor blood • Oxygen-rich blood

  6. Where does oxygen-poor blood need to go once it enters the right side of the heart? • to the lungs to get more oxygen • To the left ventricle to be pumped out to the body • To the brain

  7. Once blood has picked up oxygen from the lungs, where does it go next? a. To right side of heart b. To the left side of the heart to be pumped out to body c. To left lung

  8. Blood Flow Through the Heart Watch this short video: http://www.nlm.nih.gov/medlineplus/ency/anatomyvideos/000067.htm

  9. Answer the following questions: What are the receiving chambers of the heart called? • Ventricles • Blood vessels • Atria

  10. Answer the following questions: What are the pumping chambers of the heart called? • Ventricles • Blood vessels • Atria

  11. Answer the following questions: Which heart chamber receives blood from the vena cava? • Left atrium • Right atrium • Both left and right atria

  12. Answer the following questions: Which valve does blood go through when it passes from the right atrium to the right ventricle? • Bicuspid valve • Tricuspid valve • Pulmonary valve

  13. Answer the following questions: Which valve does blood go through when it passes from the right ventricle to the pulmonary artery? • Bicuspid valve • Tricuspid valve • Pulmonary semilunar valve

  14. Answer the following questions: Oxygenated blood travels from the lungs back to the heart through which vessels? • Pulmonary veins • Pulmonary arteries • Aorta and vena cava

  15. Answer the following questions: Which heart valve does blood pass through from the left atrium to the left ventricle? • Aortic valve • Mitral valve • Tricuspid valve

  16. Answer the following questions: When the left ventricle contracts, which valve does it pass through in order to get to the aorta? • Aortic semilunar valve • Pulmonary valve • Mitral valve

  17. Answer the following questions: What keeps blood flowing in the correct direction within the heart? • Ventricles • Blood vessels • Valves

  18. Answer the following questions: What does “vascular” refer to? • Ventricles • Blood vessels • Atria

  19. Electrical Activity of the Heart • Watch this short video: http://www.nlm.nih.gov/medlineplus/ency/anatomyvideos/000021.htm

  20. Answer the following questions: (2) What is the heart’s primary job or function? • Attach to the blood vessels • Pump oxygen-rich blood to the brain and organs of the body • Refill after rest

  21. Answer the following questions: (2) What is it called when the blood is pumped to the brain and body’s organs and tissues? • Systemic circulation • Pulmonary circulation • systole

  22. Answer the following questions: (2) What is it called when the heart pumps oxygen-poor blood to the lungs to pick up oxygen? • Systemic circulation • Pulmonary circulation • diastole

  23. Answer the following questions: (2) What is systole ? • Relaxation/refilling phase of a cardiac cycle • Pumping/contracting phase of a cardiac cycle • Blood pressure

  24. Answer the following questions: (2) What is diastole? • Relaxation/refilling phase of a cardiac cycle • Pumping/contracting phase of a cardiac cycle • Blood pressure

  25. Answer the following questions: (1) Based on the definition of word parts for CARDIOVSCULAR, what anatomical structures are included in the Cardiovascular system? • Heart and lungs • Heart and blood vessels • Heart and brain

  26. Pathological Conditions Cardiovascular System

  27. Things can go wrong. . . There are many things that can go wrong with the heart and blood vessels.

  28. Myocardial Infarction

  29. “Myocardial” in parts: My/o = cardi = -al = Muscle Heart Pertaining to Simple definition: Pertaining to the heart muscle

  30. “Infarction” in parts: Infarct = -ion = Death of tissue Process or action Simple definition: Process or action of death of tissue

  31. Parts-based Definition So, putting all of it together, we could make a simple definition for “Myocardial Infarction”: “Pertaining to death (process of dying) of the heart muscle.”

  32. Pathological Conditionsof the Blood Vessels Aneurysm (pronounced: AN-yoo-rizm) is a localized sac-like bulge in the wall of an artery. It usually forms at a weak point in the arterial wall. It can rupture and lead to serious internal bleeding.

  33. Pathological Conditionsof the Blood Vessels Arteriosclerosis (also called Atherosclerosis) Watch the short video: http://www.nlm.nih.gov/medlineplus/ency/anatomyvideos/000006.htm

  34. Pathological Conditionsof the Blood Vessels Hypertensionis a condition in which the patient has a higher blood pressure than normal (exceeds 140/90 mmHg).

  35. Thrombophlebitis

  36. Comprehension Check: What is the definition you learned for “Pathological”? • Pertaining to the heart • Pertaining to discomfort • Pertaining to the knowledge/study of diseases

  37. Comprehension Check: Which of the following choices are good examples of signs and symptoms related to problems with the heart and blood vessels? • Choking, coughing • Anxiety, chest pain • Runny nose, headache

  38. Comprehension Check: What does “coronary” mean? • Pertaining to muscle • Pertaining to the blood vessels • Pertaining to the heart

  39. Comprehension Check: Which term means “pertaining to the heart muscle”? • Coronary • Myopathy • Myocardial

  40. Comprehension Check: Condition of extremely rapid, incomplete and ineffectual twitching-like contractions of the ventricles; often results in cardiac arrest. • Ventricular tachycardia • Ventricular fibrillation • Ventricular flutter

  41. Comprehension Check: Caused by a partially blocked coronary artery, this condition is considered a “warning” of a possibly bigger cardiac event in the future. • Myocardial Infarction • Heart Attack • Angina Pectoris

  42. Comprehension Check: Caused by a completely blocked coronary artery, this event is a medical emergency because more heart tissue can die with each passing minute. • Myocardial Infarction • aneurysm • Angina Pectoris

  43. Comprehension Check: A test used to help determine if an MI occurred; relates to an elevated amount of “released” cardiac enzymes. • angiography • Cardiac enzymes test • Cardiac catheterization

  44. Comprehension Check: A record or picture used to help determine abnormalities of the electrical action of the heart muscle. • Electrocardiogram • echocardiography • Event monitor
