Description

FAM1291: Human Physiology and Health 2 - Online Test 7: Heart (CV System) Blood enters the right atrium of the heart With a low concentration of oxygen Mitral valve prolapse is caused by A faulty valve located between the left atrium and left ventricle A myocardial infarction is caused by a lack of oxygen to Cardiac muscle cells Angina is be experienced as pain in the chest and/or in Either or both arms Between the shoulder blades Neck and/or jaw Abnormally slow heart rate is called Bradycardia Tachycardia is Abnormally rapid heart rate The spread of electrical activity in the heart follows which of the following paths? Pacemaker cells, atria, AV node, ventricles Blood leaves the left ventricle of the heart Through the aorta to supply blood to body tissues Blood leaves the left ventricle of the heart With a high concentration of oxygen Congenital heart defects Are caused by abnormal development of the heart structure May be associated with genetic syndromes May not require surgical treatment Congestive heart failure Occurs because the heart muscle has weakened and is unable to pump the same quantity of blood to tissues as it receives Blood is carried toward the heart by which type of vessels? Veins Blood is carried away from the heart by which type of vessels? Arteries Each heart beat is initiated by Pacemaker cells located in the right atrium

The semilunar valves are located between the Ventricles and the large arteries leaving the heart Pain associated with angina is described as Sharp and stabbing Burning (as occurs with indigestion) A sensation of extreme pressure Ventricular fibrillation means that the Ventricles have stopped pumping blood and a carotid pulse will not be detected The tricuspid valve is located between the Right atrium and right ventricle A surgical procedure that involves passing a catheter into an artery, inflating a balloon and inserting a stent to widen the lumen of a narrowed blood vessel is called Angioplasty The right ventricle pumps blood to The lungs The layer of muscle within the heart is called the Myocardium Beverley is experiencing pain in her back, shoulder and jaw along with shortness of breath that wakes her up at night. Her symptoms Should be treated as a cardiac emergency because they could lead quickly to a myocardial infarction Angina is Pain originating from the heart due to lack of oxygen to cardiac tissue Angina Is caused by a lack of oxygen to cardiac muscle cells Atrioventricular septal defect involves an opening between the left and right atria and between the left and right ventricles as well as A-V heart valve abnormalities Pain associated with angina is described as Sharp and stabbing Burning (as occurs with indigestion) A sensation of extreme pressure Stable angina Is cardiac pain that is usually relieved by resting or relaxing

FAM1291: Human Physiology and Health 2 - Online Test 7: Heart (CV System) The inner lining of the heart is called the Endocardium The outer lining of the heart is called the Epicardium An atrial septal defect is An opening between the left and right atria The mitral valve is located between the Left atrium and left ventricle The main function of the cardiovascular system is Transporting oxygen, nutrients and waste products to and from cells The two large chambers located at the bottom of the heart that pump blood to the body are called Ventricles The two small chambers located at the top of the heart that collect blood from the body are called Atria The most common type of congenital heart defect for persons with Down syndrome is Atrioventricular septal defect An electrocardiogram Is a recording of the electrical activity in the heart The cardiac cycle is All of the events that take place within the heart during one heartbeat A ventricular septal defect is An opening between the left and right ventricle In addition to angina, clinical symptoms of a myocardial infarction could include which of the following? Denial and/or feeling of impending doom Shortness of breath Nausea Coronary bypass surgery is a surgical procedure that Uses an artery or vein graft to reroute blood around a blocked artery in the heart

FAM1291: Human Physiology and Health 2 - Online Test 7: Heart (CV System) Atherosclerosis is a serious medical concern because Plaque deposits injure blood vessel walls Arteries lose their elasticity increasing blood pressure Arteries are narrowed and may become entirely blocked Sinus rhythm refers to Normal electrical activity of the heart Heart murmurs caused by leaky valves are often associated with which of the following genetic syndromes? Fragile X syndrome Down syndrome Williams syndrome Heart murmurs that are caused by heart valves that are not functioning properly May be repaired or replaced with a prosthetic valve Heart murmurs Are abnormal heart sounds An opening in the septum of the heart Results in a flow of oxygenated blood from the left side into the right side of the heart Decreases the efficiency of the heart Increases the workload on the right side of the heart The heart is Made up of two separate pumps Atherosclerosis is linked to (choose all that apply) Smoking Genetic factors High levels of LDL cholesterol in the blood The QRS wave of the electrocardiogram (ECG) indicates Electrical activity in the ventricles The most appropriate description of a myocardial infarction would be Death of cardiac muscle cells If blood pressure falls, heart rate will Not change A left to right shunt means that Blood moves abnormally from the left side of the heart into the right side of the heart

Congestive heart failure could be caused by Hypertension Repeated myocardial infarctions Congenital heart defects A pacemaker is used to treat Cardiac arrhythmias Which of the following events occur during the period of the cardiac cycle called diastole? The atria contract Blood enters the right atrium of the heart Via the vena cava Right heart failure usually results in Fluid (edema) in the body tissues Left heart failure usually results in Fluid (edema) in the lungs Which heart valves are open during systole? Both semilunar valves During the period of the cardiac cycle called systole The ventricles contract The sling-like structure that attaches the heart to surrounding structures such as the diaphragm and the large blood vessels that attach to the heart is called the Pericardium Atherosclerosis is a disease process in which Plaque is deposited within artery walls An arrhythmia Is an abnormal heart rhythm Heart sounds ("lub dup�. lub dup�.) are caused by Opening and closing of heart valves The main purpose of the valves located within the heart is to Keep blood flowing in one direction through the heart Which of the following statements about congenital heart defects is not true? Congenital heart defects may develop in adulthood.

FAM1291: Human Physiology and Health 2 - Online Test 7: Heart (CV System) The most important function of cardiac cells in the AV node is to Delay the spread of electrical activity so that the atria contract before the ventricles The neurotransmitters that are released by sympathetic nerves in the heart include Epinephrine and norepinephrine Heart rate is controlled by Sympathetic and parasympathetic nerves that act on pacemaker cells and the AV node Automated external defibrillation Delivers an electric pulse that temporarily stops electrical activity in the heart
