Study Notes
The text provides information on blood pressure, its measurement, and regulation. Blood pressure is the force that pushes blood along and is regulated by various mechanisms in the body, including receptors in the carotid artery. Blood pressure can be measured using a sphygmomanometer, which detects the pulse wave and provides readings for systolic and diastolic pressure. High or low blood pressure may be a sign of disease. The heart pumps blood and is regulated by the sinoatrial node (SAN), which emits impulses that cause the atrial and ventricular muscles to contract. The SAN rate of firing can be affected by various factors, including exercise, blood pressure, and levels of carbon dioxide and oxygen in the bloodstream. Adrenaline can also increase the heart rate. Coronary heart disease is a major cause of death and requires further study.
