Physiology

The physiology of return circulation is complex and still involves many unknowns. It has to
perform several functions:

returning blood to the right side of the heart

cutaneous thermoregulation

regulation of the cardiac flow

reservoir of blood mass
It has to deal with difficult conditions that have been known for a long time. Bipedality
aggravates the hydrostatic and hydrodynamic factors that it has to combat, resulting in venous
hyperpressure.
This venous hyperpressure, responsible for micro-circulatory problems, is the key factor in
venous ailments and their potential for development.
Gradual functional adaptation over thousands of years, with a unique venous blood propulsion
system deals with the main problems posed by gravity. However, the effectiveness of these
adaptation mechanisms is being challenged by modern living conditions.
Even though these physiological blood return mechanisms are partly known, their respective
importance has not yet been properly defined.Many factors are involved in venous dynamics.

3.4.1. The muscular and articular pump

The contraction of the calf muscles during effort compresses the veins and favours the flow of
Hg after 30 seconds. The hemodynamic repercussion is rapidly felt upstream with an increase
in capillary pressure and the appearance of an edema.

blood towards the heart. The effectiveness of this
contraction depends a great deal on the articular condition
of the ankle and to a lesser degree of the knee.
Squeezing the plantar venous sole allows the blood to flow
to the deep venous trunks and the saphenous veins.
Around 30 ml of blood is expelled each time the foot comes
into contact with the ground.
The contraction of the calf muscles: the blood mass is
ejected towards the heart by the compression of the
muscular veins and deep veins. The deep vein valves
prevent reflux upstream and towards the superficial venous
network. The non-extensible aponeuroses limit the dilation
of the calf muscles. Naturally, the effectiveness of this
muscular pump depends on the development of this
muscular mass (especially the gemellary and solear
muscles).
It will be much larger in sporting than sedentary persons, in
men than in women.
The sural venous muscular pump, a veritable peripheral
pump, reduces the distal venous pressure by 40% and the
blood sequestered by orthostatism by 200 ml. In an
immobile standing position, the venous pressure is 90 mm
