Anonim

The vasoconstriction is a place in the phenomenon blood vessels which involves the reduction of the structure of it, the blood vessels to be distributed throughout the system have the characteristic of being vulnerable to any changes homogeneous and heterogeneous receive the body from the outside. Vasoconstriction is a process of isolation from the blood. When a vessel narrows, it is for the system a stoppage of flow, a consequence that is useful at a medical level for extracting 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 unintermittent flow, this flow can be intervened by low temperatures, since the vessels that are normally dilated (Vasodilation) are 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 the blood traffic present in the veins in which an agent that alters the behavior of the fluid is applied.

One way to see vasoconstriction more easily is with the following example: hoses that carry nitrogenous compounds must have a specific external density and temperature, otherwise the current may stop 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. The obesity uncontrolled produce blood clots that clog veins that go to the heart, it can cause death. Poor circulation in the veins of the legs in the elderly are called " varices ".

By the time 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 joints involved.
