Answers: Tricuspid valve Mitral valve Pulmonary valve Aortic valve Question 2 Which type of blood cell assists in the hemostasis process? Answers: Red blood cells White blood cells Neutrophils Platelets Question 3 Which chamber of the heart receives blood from the lungs? Answers: Left ventricle Right ventricle Left atrium Right atrium Question 4 Which terms refers to the amount of blood pumped by the heart in one minute? Answers: Cardiac output Heart rate Stroke volume Ejection fraction Question 5 Which chamber of the heart pumps blood out to the systemic (body) circuit? Answers: Left ventricle Right ventricle Left atrium Right atrium Question 6 Blood cells are produced in the red bone marrow found within spongy bone of the skeletal system. Answers: True False Question 7 The parasympathetic nervous system causes an increase in heart rate. Answers: True False Question 8 What role do the heart valves have within the function of the heart? Answers: They help pump the blood from one chamber to another. They help prevent the backflow of blood through the heart. They assist with the cardiac conduction system. They assist with the protection of the heart. Question 9 Which disorder is characterized by an excessive white blood cell count? Answers: Leukemia Anemia Polycythemia Sickle cell disease Question 10 What blood type is the universal donor? Answers: Type A Type AB Type B Type O Question 11 The right ventricle will pump oxygenated blood to the lungs. Answers: True False Question 12 What is true of the cardiac conduction system (pacemaker) of the heart? Answers: It causes the left side of the heart to contract first then the right side. It causes the right side of the heart to contract first then the left side. It causes both atria to contract then both ventricles to contract. It is controlled by conscious thought. Question 13 Which portion of the cardiac conduction system sets the heart rate? Answers: SA node AV node AV bundle Purkinje fibers Question 14 Which layer of the heart is the thickest and performs the work of the heart? Answers: Endocardium Epicardium Myocardium Pericardium Question 15 Which chamber of the heart pumps deoxygenated blood to the lungs? Answers: Left ventricle Right ventricle Left atrium Right atrium Question 16 Congestive heart failure occurs when a ventricle fails to effectively pump blood. Answers: True False Question 17 Which blood cells are responsible for transporting oxygen throughout the body? Answers: Erythrocytes Granulocytes Lymphocytes Monocytes Question 18 Which structure is responsible for carrying an impulse to both ventricles, causing them to contract at the same time? Answers: Atrioventricular node Bundle of His Purkinje fibers Sinoatrial node Question 19 The majority of plasma is composed of: Answers: Proteins Blood cells Water Solutes Question 20 The pericardium is the inner layer of the heart. Answers: True False
