Varicose veins – payback for upright walking
The evolutionary transition of human ancestors to upright posture was accompanied by verticalization of the trunk, as well as an increase in the length and muscles of the legs. But even 5 million years was not enough for the organism to adapt to such radical changes that a unique disease – varicose veins of the lower extremities – backfired on modern man. Up to 60% of the population of developed countries suffers from this disease, which is not observed in animals and even primates. I propose to understand the causes of varicose veins through the prism of evolution in order to find the best recommendations for solving such an urgent health problem.
The heart is located in the body of animals in such a way as to minimize the length of the vascular bed and the energy consumption for pumping blood to all parts of the body. It follows from this that, all other things being equal, the optimal place for the heart is in the center of the body.
