This process in our body Although it is quite remarkable, is the pumping of the heart alone enough?

This system, which seems impossible, is in reality impossible alone is not enough. Let us explain.

The blood in our legs flows upwards despite gravity.

While this is a very intriguing event, the pumping power of the heart is to get the blood flowing down the legs It is not enough. Here comes a second system: the cooperation between our muscles and the valves in our veins.

Human body, transport the blood from our legs back to our heart Many mechanisms have been developed for this Small valves along the veins prevent the backflow of blood. These valves work together with the contraction of our leg muscles, allowing the blood to move in one direction.

Especially during walking, standing and other physical activities, our muscles help pump blood around by compressing the blood vessels.

This process “musculo-venous pumping” It is called and provides effective resistance to gravity. However, sometimes these valves may not work properly and blood may leak backwards.

In this case, the veins in the legs swell and varicose veins develop.

David J.Tibbs As he notes, gravity is constantly working against the venous system of our limbs. If the valves are dysfunctional, the blood can flow backwards and there can be a corresponding increase in venous pressure.

Don’t forget regular exercise for healthy blood circulation.

Activities such as walking, running, cycling, activating your leg muscles It increases blood circulation and thus supports venous conversion. This simple yet effective method offers a natural solution to improve blood flow in your legs.
