This sound is made by the rapid contracting and extending of the chamber doors on the inside of the heart. This ventricular contracting injects roughly 70 mL of blood into a vascular system with a given volume at differing pressure. Blood pressure refers to the pressure in the arterial system; and it is typically taken in the brachial artery of the arm because the pressure at different places along the circulatory route is different. Blood pressure is simply the force that the blood exerts in all directions within any given area and is the basis for the movement of blood from the heart, through the body, and back to the heart. This pressure is commonly expressed as a ratio of the systolic pressure over the diastolic pressure. The systolic pressure or "high peak" pressure takes place within the arterial system as ventricles contract and force blood into the arteries. The diastolic pressure or "low peak" pressure takes place within this arterial system just before the next ventricular contraction. An increase in blood pressure can occur if the arterial walls lose some of their elasticity with age or disease. What is the main idea of the passage? A. Blood pressure overall measures the elasticity of the arteries near the heart as they stretch to accommodate expelled blood. B. Blood pressure within the arterial system takes into account that pressure is different at varying locations. C. Blood pressure is simply the force that the blood exerts in all directions within any given area, measured as a ratio. D. Blood pressure represents the pulse difference between ventricular contractions. C.

The signal cadence has a characteristic record that varies in every individual. This record is called an electrocardiogram, or ECG. In the body, an array of systemic neural responses constantly occurs, emitting electric currents. The electric currents can be detected on the surface of the body, and if a person is hooked to an amplifier, these impulses are recorded by an electrocardiograph. Most of the information obtained is about the heart because the heart sends out electric currents in waves. This "wave of excitation" spreads through the heart wall and is accompanied by electric changes. The wave takes place in three distinct steps. Initially, the "wave of excitation" accompanied by an electric change lasts for approximately 1 to 2 seconds after the contraction of the cardiac muscle. The electric impulses are discharged rhythmically from the sinoatrial (SA) node, the pacemaker of the heart. This spread of excitation over the muscle of the atrium indicates that the atrium has contracted. Next, the peak of the ECG reading is due to the atrioventricular (AV) node causing the ventricle to become excited. Finally, the ventricles relax, and any changes in the wave indicate to trained medical staff any abnormalities within the heart. What is the author's primary purpose in writing the essay? A. To persuade the reader to have an ECG B. To entertain the reader with a heartwarming story C. To inform the reader how an electrocardiograph reads the electric currents emitted by the heart D.
