Oxygen-rich blood from the lungs enters through the pulmonary veins on the left side of the heart into the aorta and then reaches the rest of the body. The capillaries are responsible for allowing the blood to receive oxygen through tiny air sacs in the lungs.
The pulsating calf contractions compress deep veins and pump the venous blood against gravity towards the heart. We can highlight 3 principal hemodynamic effects: [1] [5] [6] removal of venous stasis; increase of venous outflow in terms of volume and velocity; inhibition of reflux in superficial and deep veins.
