Blood pressure is the measure of the pressure against the walls of the arteries. There are two forces that form blood pressure. One of the forces is created when the heart pumps blood into the arteries through the circulatory system. The other force is due to the arteries as they resist the flow of blood. Blood pressure is always stated in two numbers‚ systolic pressure and diastolic pressure. The higher number is systolic pressure which represents the pressure while heart contracts to pump the blood

A heart attack‚ also known as a myocardial infarction‚ usually occurs when a blood clot forms inside a coronary artery at the site of an atherosclerotic plaque. The blood clot severely limits or completely cuts off blood flow to part of the heart. In a small percentage of cases‚ blood flow is cut off when the muscles in the artery wall contract suddenly‚ constricting the artery. This constriction‚ called vasospasm‚ can occur in an artery that is only slightly narrowed by atherosclerosis or even in

Water Balance Adipose tissue is one of the most hydrated of all tissues in the human body. False The most abundant cation in intracellular fluid is sodium. False Electrolytes determine most of the chemical and physical reactions of the body. True Solutes‚ regardless of size‚ are able to move freely between compartments because water carries them along the osmotic gradients.False The thirst center in the brain is located in the hypothalamus.True Dehydration can be caused by endocrine disturbances
