Varicose veins

Varicose veins: blood circulation problem


Inside the veins there are valves approximately every inch. They have the function of preventing blood reflux at the moment of diastole (relaxation of the left ventricle of the heart).

Causes, characteristics and other information

When the left ventricle contracts (systole) normally the blood pressure rises to "12", which causes the walls of the veins to dilate.

In diastole, although the pressure usually decreases to "8", the blood continues to circulate because the veins have elastic fibers that cause them to contract, and thus push the blood.

In addition to elastic fibers, the action of skeletal striated muscles assists the vein in this contraction.

In sedentary lifestyle, muscle aids become too low, resulting in widening of the veins and causing the blood pressure to become lower, resulting in difficulty in venous return.

As the picture gets worse, the valves become inoperative and become increasingly difficult to circulate, this is how the varicose veins appear.

Useful information: There are some brands of socks on the market that help to prevent varicose veins.
