The vasodilation is the reverse process to vasoconstriction in which blood vessels receive an external influence and they increase in size to form a more hollow cavity and allow greater flowof blood. Vasodilation is the main principle of blood flow stimulants, which are useful to improve blood traffic in areas of the body that due to conditions, or if a process of vasoconstriction has begun over time. The pathways through which the blood passes suppose a current of vital fluid (blood) in the human being, for its correct functioning it should neither be dilated nor obstructed, but in the case that a blockage is found in the vein, it is necessary to resort to duct dilation processes.
These expansion processes are generally thermal. Thermoregulation of blood vessels through the application of heat allows expansion of the vessels towards the vein walls, clearing the path for compromised fluid. However, the application of clinical vasodilation has taken on a field of study that is currently a benchmark in society, such as erectile dysfunction.
Erectile dysfunction consists of the absence of the correct path of blood through the cavernous tissues of the penis, although it is true that in most cases there is no constriction present that prevents the penis from filling with blood to become erect, there is no stimulus complex that allows the filling of the adipose body with fluid. Medicines such as sildenafil, tadafil (in their commercial presentations " Viagra and Cialis") act as a vasodilation agent for the blood-conducting veins, leaving free passage (after sexual stimulation) to the correct dilation of the blood vessels of the penis.
The spontaneous vasodilation of a tissue implies the rapid and premature response of this to establish a greater but required blood flow, strong emotions, such as joy, despair, lead to a greater work of the heart when pumping blood, which brings as a consequence a widening of the veins to give way to a more consistent and strong flow.
