Capillariea are tiny blood vessels that pass blood from the arteries into the veins. They are very small, the largest being about 10 micrometers in diameter. Their walls are thin which allows materials to pass into the capillaries. Different types of capillaries exists and perform different functions for the body.
Microcirculation supplies oxygen and nutrients to heart tissue and all of the 75 trillion cells that comprise the human body. In fact, each cell in the body has its own personal blood supply no further than 1/500th of an inch from the 100000 kilometres of capillaries that comprise the microcirculatory system of the human body. Microcirculation also is important to the regulation of coronary blood flow.
Microcirculation abnormalities often occur in subjects with high blood pressure. In fact, it is now thought that the microvascular changes that occur in hyperttensive people may play a role in the end-role organ damage often seen in this disease, including heart disease.
In hypertension, the microvascular walls thicken and the lumen, the space within an artery, narrows, ultimately resulting in the blockage of vessels.
This reduces the number of capillaries and small blood vessels known as arterioles. These destructive changes are known to occur in the microvascular system that feeds the heart muscle, the conjunctiva and retina, and the kidneys.
Dysfunction in the microcirculatory system (microangiopathy) is also a significant problem in diabetics, depriving their tissues of nutrients and oxygen and decreasing the ability to remove toxins.
Clearly, microcirculation is an essential, but often poorly recognized, factor in heart health. Therefore, enhancing the microvascular system is as important as maintaining healthy cholesterol levels or tending to other aspects of cardiovascular health.
The properties of capillaries are highly varied depending on where they are.
Kidney capillaries have lots of microscopic holes so that substances may easily pass through them and be excreted
Liver capillaries look almost like coiled snakes, making many loops back and forth in liver tissue to allow ample time to filter harmfuk materials from the blood.
Brain capillaries are very tight with almost no holes to protect fragile brain tissue.
Targeting the microcirculation in health programs is key to maintaning the vitality and health that should last our entire lifetimes. Unfortunately lifestyle, habits and disease that are sprawned as a result have the effect of debilitating the microcirculation, which leads to further compounding of the disease process.
Life is an eternal movement of liquids between cells and inside cells. The stop of this movement leads to death. Partial delay of movement of liquids in any organ causes partial disorder. The general delay out of - and intracellular fluid in an organism causes disease.
In case if any organ supplied with blood insufficiently or lost blood circulation its activity against an infection is catastrophically failed. In struggle against an infection capillaries are the main defender (oxidation, phagocytosis, removal of toxins).
Capillary circulation is the main area where metabolism occurs.
The quantity of open capillaries is the key to pathogenesis of each process of regeneration. Capillary disease - capillaropathy, is the most important chapter of pathology and is the base of each disease process.
