Unfortunately this disease can do a lot of damage before anyone realizes it because few people have any symptoms. Today we will talk about what high blood pressure is and how we can control it.

Resistance = tendency of the vascular system to oppose flow; Flow = Influenced by: length of the tube (L), radius of the tube (r), and viscosity of the blood (h) Poiseuille’s Law R = Lh/r4 In a normal human, length of the system is fixed, so blood viscosity and radius of the blood vessels have the largest effects on resistance 1 R All four tubes. In this article, we will consider the short term and long term control of blood pressure, as well as some of the problems when control of blood pressure is lost. Blood Pressure. The body’s blood pressure is a measure of the pressures within the cardiovascular system during the pumping cycle of the heart. It is influenced by a vast number of variables, and can alter in either direction for various reasons/5(17). • Long-term regulation of blood pressure is primarily accomplished by altering blood volume. • The loss of blood through hemorrhage, accident, or donating a pint of blood will lower blood pressure and trigger processes to restore blood volume and therefore blood pressure back to normal. Control of Blood Pressure. Changes in blood pressure are routinely made in order to direct appropriate amounts of oxygen and nutrients to specific parts of the body. For example, when exercise demands additional supplies of oxygen to skeletal muscles, blood delivery to these muscles increases, while blood delivery to the digestive organs decreases. Role of the Nervous System in Rapid Control of Arterial Pressure. Nervous control of arterial pressure is by far the. most rapid. of all our mechanisms for pressure control. When there is. drop in arterial blood pressure. there are three major changes that occur simultaneously, each of which helps to increase arterial pressure. They are as. Blood Pressure. Diastolic pressure is minimum pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood. An example of normal measured values for a resting, healthy adult human is mmHg systolic and 80 mmHg diastolic.
