Why the blood vessels are so important for blood flow
Healthy blood flow is important so that oxygen and nutrients are distributed throughout the body. Only in this way can all organs, especially our heart and brain, but also our arms and legs, be optimally supplied. Elastic blood vessels are a prerequisite for the blood to flow well through the veins and for a constant blood pressure to be maintained. The famous German doctor Rudolf Virchow put it in a nutshell: "You are as old as your blood vessels." They are crucial for our health because they form the interface between the outside world and cell function. If our body cells are not well taken care of, they begin to age. This aging process is accelerated by numerous substances such as cholesterol, calcium deposits, etc., which accelerate the hardening of our vessels. The endothelium is responsible for the elasticity of the blood vessels. This is the layer of cells that lines our veins from the inside. It regulates the exchange of substances between blood and tissue. One of these substances is nitric oxide (NO), which ensures that the veins can dilate. If the endothelium no longer produces enough NO, the blood vessels cannot dilate and blood circulation is impaired. Especially in the smallest branches of the blood vessel system, the narrow capillaries, the elasticity of the veins is so important so that the blood can flow well here.
