What is a vascular tone?

Vascular tone is a medical term used to describe the diameter and tone of the blood vessel when the container is fully extended. Under normal conditions, all blood vessels experience at least a slight degree of contraction of the smooth muscles of the blood vessel. These contractions are used to determine the vascular tone. If this tone is normal, they are considered to be functional blood vessels at an optimal level. When these contractions become abnormal, vascular health may be disrupted, requires a trip to a doctor for proper diagnosis and treatment. When measuring vascular tone, both types of blood vessels, arteries and veins are considered. The artery is a blood vessel that carries pure blood from the heart to different tissues and body organs. The vein is the type of blood vessels responsible for transporting blood back to the heart after the tissues and organs have obtained oxygen and nutrients from the blood.

Vascular tone naturally differs between organs. The reason is the differences in the vasodilator capacity. This means that organs receiving faster blood flow will have a higher vascular tone than the organs that enoughThey are slower blood flow. For example, myocardium is the strongest of the heart muscles and has a high vascular tone. Conversely, the kidneys and other kidney organs have a much lower vascular tone.

While there are several factors that may affect the vascular tone, these factors are generally divided into two categories. External factors are those that start outside tissue or organ where there is a blood vessel, such as the control of blood flow through sympathetic nerves. The internal factors are factors that start either in the actual blood vessel itself or in tissues that immediately surround the blood vessel; Chemicals or hormones produced by an organ that affects blood flow or blood pressure factors.

Some health conditions, including heart disease or high blood pressure, have the potential to cause vascular tone dysfunction. If this type of dysfunction is suspected, medical intervention becomes very importantteam. Routine medical testing is often able to detect the problem before it turns into a life -threatening situation. In many cases, a combination of dietary changes and prescription drugs is sufficient to restore the right blood vessel health. Surgery sometimes becomes necessary depending on the patient's overall health.
