Which of the following is false regarding Atherosclerosis? a. It is the accumulation of fat along the inner walls of the arteries. This build up is called plaque and over time, the plaque hardens which stiffens and narrows the arteries causing a rise in blood pressure further damaging the artery walls. b. Causes the heart has to work harder to pump blood through the narrowed and hardened arteries. c. Can form blood clots faster than they are dissolved. If the clot becomes dislodge and gets stuck in a smaller artery the nearby tissue can’t get any nutrients. A large clot stuck in the heart causes a heart attack! A large clot stuck in the brain causes a stroke. d. All are true. 17. Put the Path of blood in order. ___. Superior vena cava, inferior vena cava, and coronary sinus poor oxygen-poor blood into the right atrium. ___. Oxygen-poor blood enters the right ventricle. ___. Oxygen-poor blood is pumped into the pulmonary trunk. ___. Oxygen-poor blood enters the pulmonary arteries. ___. Oxygen-poor blood enters the lungs to release carbon dioxide and pick up oxygen. ___. Oxygen-rich blood enters the pulmonary veins. ___. Oxygen-rich blood enters the left atrium. ___. Oxygen-rich blood enters the left ventricle. ___. Oxygen-rich blood is pumped to the aorta to the rest of the body. 2 True or false – read each statement. If the statement is true, write “TRUE”. If false, correct the underlined word so that is reads true. ______________________________ 1. Arteries of the lower body, found below the heart, are equipped with valves to prevent the back flow because it flows against the force of gravity. ______________________________ 2. A health heart has a blood pressure of 140 mmHg. ______________________________ 3. When the ventricles contract this is called ventricular systole creating the systolic blood pressure (120 mmHg). ______________________________ 4. When the atrium relax, this is called ventricular diastole creating diastolic blood pressure (80 mmHg). ______________________________ 5. Coronary arteries brings oxygen-poor blood to the tissues of the heart. ______________________________ 6. Coronary veins drain oxygen-rich blood from the tissues of the heart. Matching – all answered will be used only once. More questions on the next page. ___ 7. “choked chest” results from spasms that block the coronary artery and cuts of blood supply to the myocardium causing chest pain and pressure. ___ 8. Blood vessels that carry blood from the capillaries back to the heart, usually oxygen-poor. 65% of blood is found here. ___ 9. Blood vessels that form a dense networks found in all tissues of the human body. So tiny that red blood cells can pass only one at a time! ___ 10. Hearts rates that are abnormally slow, under 60 beats per minute. ___ 11. Hearts rates that are higher than 100 beats per minutes. If persists for along period of time the heart will beat erratically and eventually stop functioning. ___ 12. High blood pressure. Having a systolic pressure more than 140 mmHg and a diastolic pressure more than 90 mmHg. Can be caused by a number of factors all resulting in an increased resistance to blood flow in vessels. When the pressure is higher, it is harder for blood to flow. ___ 13. Prevents back flow of blood from the pulmonary trunk into the right ventricle. ___ 14. Prevents the back flow of blood from the aorta into the left ventricle A. B. C. D. E. F. G. H. I. J. K. L. M. N. O. P. Q. R. S. T. U. V. Angina pectoris Aortic semilunar valves Arteries Atria Atrioventricular Biscuspid valve Bradycardia Capillaries Endocardium Epicardium Fibrous Hypertension Left atrium Left ventricle Myocardial infarction Myocardium Oxygen-poor pericardium Pulmonary semilunar valves Right atrium Right ventricle Serosal 3 ___ 15. The blood vessel that transport blood away from the heart, usually oxygen-rich. ___ 16. The bottom chambers of the heart responsible for pumping blood out of the heart. ___ 17. The chamber of the heart that receives oxygen-poor blood from 3 major blood vessels (superior vena cava, inferior vena cava, and coronary sinus). ___ 18. The chamber of the heart that receives oxygen-rich blood from the lungs. ___ 19. The covering around the heart ___ 20. The covering around the heart that anchors the heart and wards off infection. ___ 21. The covering around the heart that keeps the heart lubricated by secreting a substance called pericardial fluid. ___ 22. The death of cardiac muscle cells due to prolonged blockage in the coronary blood vessels. This leads to inadequate blood flow and inadequate oxygen delivery. If deprived of oxygen too long, the cardiac muscle is damaged this damaged tissue is replaced with scar tissue that impedes the flow of blood resulting in a heart attack. ___ 23. The inner most layer of the heart wall that melds with the blood vessels of the heart. ___ 24. The middle layer of the heart wall. This layer is the thickest, is filled with blood vessels, and is responsible for the heart contracting. ___ 25. The outermost layer of the heart wall that helps reduce friction by secreting additional pericardial fluid. ___ 26. The superior vena cava, inferior vena cava, and coronary sinus delivers this type of blood. ___ 27. The thicker ventricle that pumps blood to the aorta to the rest of the body. ___ 28. The top chambers of the heart that receives blood. ___ 29. The trap door between the left atria and left ventricle. ___ 30. The trap door between the right atria and right ventricle. ___ 31. The trap doors between the two atrium and ventricle chambers. ___ 32. The ventricle that pumps blood to the pulmonary trunk. ___ 33. Trap doors of the heart that close to prevent the back flow of blood to ensure blood flows only in one direction. W. X. Y. Z. aa. Tachycardia Tricuspid valve Valves Veins Ventricles 4
