How to improve the condition of blood vessels
Vessels are the transport system of our body. They deliver oxygenated blood to cells and tissues, and remove metabolic products and toxins from them.
In addition, the blood flowing through the vessels warms our body and maintains body temperature at a constant level.
The important role of blood vessels in life is determined by the fact that we need to take care of them throughout life.
Blood circulation, Circulatory system, Blood vessels
Blood circulation - the circulation of blood throughout the body. In primitive living organisms, such as annelids, the circulatory system is closed and is represented only by blood vessels, and the role of the pump (heart) is performed by specialized vessels with the ability to rhythmic contractions. Arthropods also have a circulatory system, but it is not closed in a single circuit. In primitive chordates, for example, lancelet, blood circulation is carried out in a closed circuit, the heart is absent. Starting with representatives of the fish class, blood is set in motion by contractions of the heart and circulates through the vessels. Blood supplies the body tissues with oxygen, nutrients, hormones and delivers metabolic products to the organs of their secretion. Blood enrichment with oxygen occurs in the lungs, and saturation with nutrients - the digestive organs. In the liver and kidneys, neutralization and removal of metabolic products occurs. Blood circulation is regulated by hormones and the autonomic nervous system. There are small (through the lungs) and large (through organs and tissues) circles of blood circulation.
Cardiovascular system - an organ system that provides blood circulation in the human and animal body. Due to blood circulation, oxygen, as well as nutrients are delivered to organs and tissues of the body, and carbon dioxide, other metabolic products and waste products are excreted. The circulation of blood in the cardiovascular system in vertebrates and humans is supplemented by lymph drainage from organs and tissues of the body through the system of vessels, nodes and ducts of the lymphatic system that flow into the venous system at the confluence of the subclavian veins. The cardiovascular system includes the heart - an organ that makes the blood move by pumping it into the blood vessels - hollow tubes of various calibers through which it circulates. All functions of the circulatory system are strictly coordinated due to neuro-reflex regulation, which allows you to maintain homeostasis in the conditions of constantly changing conditions of the external and internal environment.
Blood vessels are elastic tubular formations in the body of animals and humans, through which the force of a rhythmically contracting heart or pulsating vessel carries out the movement of blood throughout the body: to organs and tissues through arteries, arterioles, arterial capillaries, and from them to the heart through venous capillaries, venules and veins.
What vessels are in the body?
We will not delve into the anatomical details, we only outline the main features of each type of vessel. So, in the body there are:
- Arteries. These vessels have the largest cross section and are considered trunk. According to them, blood enriched with oxygen enters all cells. The walls of the arteries are elastic and resilient: this is necessary to ensure uninterrupted blood flow. In these vessels, the blood flow speed is maximum, therefore their walls are also very strong. The largest artery in the body is the aorta, it serves as a conductor of blood to the upper and lower half of the body.
- Veins. These vessels provide an outflow of blood containing carbon dioxide and a variety of metabolic products. Thanks to them, cells are also released from toxins. Blood flow in the veins is much slower than in the arteries. This is ensured by their structure: the walls of the veins are softer than the walls of the arteries. In addition, on the walls of the veins there are special valves that impede the flow of blood. This is necessary when part of the blood must be deposited during the redistribution of blood flow.
- Capillaries. They represent the final branches of the arterial and venous channels. Thin and small capillaries approach directly to cells and tissues, where the gas exchange process takes place. The capillary network of our body is very extensive: its length is more than 100 000 kilometers. About 85 000 liters of blood passes through them per day.
- Lymphatic vessels. This type of blood vessels does not carry blood, but lymphatic fluid. Lymph is needed in order to return various substances (salts, proteins, water and others) from the cells back to the blood. Lymphatic vessels vary in diameter, and in the largest of them on the walls there are valves (like in veins) that impede the reverse flow of fluid. The walls of the lymphatic vessels are soft, because lymph is a viscous fluid that flows relatively slowly.
It is these types of vessels that provide most of the vital processes associated with the transfer of oxygen, carbon dioxide and biologically active substances.
What could happen to the vessels?
Normally, the wall structure protects the vessel from minor injuries and damage. Of course, it is possible to violate its integrity, but for this it is necessary to make an effort from the outside.
But there are situations when various pathological processes thin the vascular wall, make it less elastic, brittle. This can lead to numerous adverse effects.
For example, a vessel may burst due to too much pressure from the blood flowing through it. Most often this happens with arteries. If the vessel is damaged, this leads to bleeding. The severity of the consequences in this case depends on the scale of the bleeding and its localization. But first things first.
If a large vessel, such as a femoral artery ruptures, bleeding will be very severe. If you do not stop the blood, a person will die in a matter of minutes. It doesn’t matter exactly where the “leakage” happens: in any case, the risk of death is very high.
If a small vessel or capillary bursts, the situation can develop in two ways. When a vessel ruptures in the body, a phenomenon that is well known to all of us appears - a bruise. It is blood accumulated in the subcutaneous tissue. As a rule, such injuries are not dangerous and pass by themselves when the vascular wall is restored.
Things are much worse if a small vessel breaks in the brain. Cells of the nervous system, and the brain, in particular, are very sensitive. Even a small amount of spilled blood leads to their death. This is what happens with hemorrhagic strokes and hematomas in the brain. The part of the brain into which the blood enters dies. Consequently, the functions for which she was responsible are violated.
Recovery of nerve tissue is very slow, so lost functions may never return to their previous level of development.
Not only arteries, but also veins can suffer. They almost never break, as the speed of blood flow in them is much lower than in the arteries. But they can pathologically increase in volume and form nodes, which occurs with varicose veins . In this case, the blood flow changes, it accumulates in the dilated veins, which leads to the formation of edema.
The most dangerous situation develops with varicose veins of the esophagus. The pathological process leads to a thinning of their walls, so an increased load (for example, with vomiting) can lead to rupture of veins and the occurrence of extensive internal bleeding.
To avoid all these unpleasant and potentially life-threatening consequences, it is necessary to maintain vascular health and care for them throughout life.
How to detect vascular problems?
To understand that your vessels need help, it is not necessary to wait for the bright manifestations of their pathology. There are signs that can be noticed much earlier:
- frequent headaches and dizziness;
- fatigue, weakness, apathy;
- weather sensitivity;
- ripples and flickering of "flies" before the eyes;
- bad sleep;
- shortness of breath even with slight physical exertion;
- a feeling of heaviness and pressure in the heart;
- drowsiness and lethargy during the day, even if you had a good night's sleep;
- cold hands and feet even in warm weather;
- numbness and tingling in the fingers of the upper and lower extremities;
- feeling of heaviness in the legs;
- leg cramps;
If one or more of these symptoms periodically bothers you, you need to urgently start preventative measures.
How to care for vessels?
In order to maintain the health of blood vessels, it is necessary to strengthen their walls. This can be done with a few simple methods that are available to everyone.
One of the most effective ways to prevent vascular disease is a contrast shower. Warm water will expand the vessels, and cold water, on the contrary, will narrow them. Such a training will preserve the elasticity of the vascular wall. In addition, the procedure improves metabolism and gas exchange. The best time for a contrast shower is morning. Start the procedure with warm water, and then increase its temperature to the limit that you can tolerate. After that, switch to cold water, lowering its degree. Repeat the rotation 5 to 6 times. Finish the procedure with cool water.
Proper nutrition plays an equally important role in the prevention of vascular diseases. It is necessary to add to the diet foods rich in vitamins C and PP, as well as potassium. These substances are found in sufficient quantities in cabbage, carrots, bell peppers, radishes, beets, apples, citrus fruits, bananas and other fruits and vegetables. Fresh greens and buckwheat are also useful.
Physical education also supports the walls of blood vessels in good shape. Exercise at a calm pace every morning without overloading yourself. Walk more, swim if possible. A good effect is given by cardio training on a treadmill, bicycle trainer. But they are not suitable for everyone, therefore, before starting classes, a cardiologist should be consulted.
Massage helps to improve the condition of blood vessels. Knead your limbs regularly at home, but do not press the skin too hard, otherwise you may damage the vessels. Remember! With varicose veins and thrombosis, massage is contraindicated.
All these procedures will bring good effect only if they are carried out regularly. Another condition for success is a complete rejection of bad habits. Otherwise, smoking and alcohol abuse can negate all your efforts to strengthen blood vessels.
Take care of your vessels - and they will last you a very long time .
