Question 12 options: a) Pressure on surrounding organs b) Poor oxygenation c) Formation of atherosclerotic lesions d) Impaired blood flow Save Question 13 (0.5 points) Which statement is true concerning the cells’ ability to synthesize cholesterol? Question 13 options: a) Cell production of cholesterol is affected by the aging process. b) Cells produce cholesterol only when dietary fat intake is low. c) Most body cells are capable of producing cholesterol. d) Most cholesterol produced by cells is converted to the low-density form. Save Question 14 (0.5 points) What is the trigger for angina pectoris? Question 14 options: a) Atherosclerotic lesions b) Hyperlipidemia c) Myocardial necrosis d) Myocardial ischemia Save Question 15 (0.5 points) Individuals being effectively managed for type 2 diabetes mellitus often experience a healthy decline in blood pressure as a result of which intervention?
