Vasoconstriction


Vasoconstriction is a phenomenon that occurs in the blood vessels which consists of the reduction of its structure, the blood vessels, being distributed throughout the system, have the characteristic of being vulnerable to all the homogeneous and heterogeneous changes that the organism receives from the outside. Vasoconstriction is a process of isolation of the blood. When a vessel narrows, it is a stoppage of flow for the system, a consequence that is useful at the medical level for the extraction of special tissue samples or some type of surgical intervention in which blood represents an obstacle to visibility.

The heart, in its constant pumping of blood throughout the body, creates an uninterrupted flow, this flow can be intervened by low temperatures, since the vessels that are normally dilated (Vasodilation) have been cold, they seek heat production to continue to measure its function by means of vasoconstriction. This defense mechanism of the object produces a decrease in the speed of blood traffic present in the veins in which the agent that alters the behavior of the fluid is applied.

A way to see vasoconstriction more easily is with the following example: the hoses that carry nitrogenous compounds must have a specific density and external temperature, otherwise it is possible that the current stops and this leads to cooling problems.

Vasoconstriction has other names when it becomes a disease, since the obstruction of arteries and veins without clinical or surgical reasons represents a serious failure in the body. Uncontrolled obesity produces blood clots that block the veins that go to the heart, this could cause death. Poor circulation in the veins of the legs in elderly people is called “Varicose veins”.

For when these cases of vasoconstriction occur, relaxation treatments have been created for the affected veins and arteries, some with the influence of electricity, others with the simple movement of the involved joints.
