Answer the review questions. Several of these questions are copied verbatim from the test. The cardiovascular test will be Thursday, April 12.
Due ???
Review for test: 1. The outermost layer of the pericardium 2. The lining of the heart 3. Heart muscle 4. The pacemaker of the heart 5. The point in the conduction system of the heart where the impulse is temporarily delayed
6. Prevents backflow into the left atrium 7. Prevents backflow into the right atrium 8. True or False: The myocardium receives its blood supply directly from the carotid arteries. 9. True or False: A heart rate of less than 60 beats/min is called tachycardia. 10.True or False: The atria receive blood returning to the heart. 11.True or False: Congestive heart failure means that the pumping efficiency of the heart is depressed so that there is inadequate delivery of blood to body tissues.
12.True or False: Tissues damaged by myocardial infarction are replaced after a long time because myocardial cells replicate slowly. 13.True or False: The left side of the heart pumps a larger volume of blood than the right since the left side feeds the entire body except the lungs.
14.Normal heart sounds are caused by ________. 15.The left ventricular wall of the heart is thicker than the right wall in order to________. 16.Blood within the pulmonary veins returns to the ______. 17.Blood enters which of these vessels during ventricular systole? A. Aorta
C. pulmonary veins
B. pulmonary arteries
D. both a and b
18.Blood is carried to capillaries in the myocardium by way of the _______ arteries. 19.Which of the following factors does not influence heart rate? A. Skin color
C. gender
B. Age
D. body temperature
20.Define systole and diastole. Which heart chambers are usually referenced when these terms are used? 21.Largest artery of the body 22.Carries oxygen rich blood from the lungs 23.Which is greater: oxygen concentration in pulmonary arteries or oxygen concentration in pulmonary veins. 24.Which is greater: systolic pressure or diastolic pressure
25.True or False: The largest of the circulatory routes is the systemic route. 26.True or False: All arteries of the systemic circulation branch from the superior vena cava. 27.True or False: Hypotension is generally considered to be systolic blood pressure above 100 mm Hg. 28. True or False: Capillaries directly connect arterioles to venules. 29.True or False: Pulmonary circulation does not directly serve the metabolic needs of body tissues. 30.Which type of blood vessels contain valves and what is their function?
