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 excrete 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 vessels in vital activity is caused by the fact that we need to take care of them throughout our life.
Blood circulation, Cardiovascular system, Blood vessels
Circulation - blood circulation through the body. In primitive living organisms, such as annelid worms, the circulatory system is closed and is represented only by blood vessels, and specialized vessels with rhythmic contractions function as a pump (heart). The circulatory system is also present in arthropods, but it is not closed into a single circuit. In primitive chordates, such as lancetnik, the blood circulation is carried out in a closed circuit, the heart is absent. Starting with representatives of the fish class, blood is driven by contractions of the heart and circulates through the vessels. The blood supplies the tissues of the body with oxygen, nutrients, hormones and delivers metabolic products to the organs of their release. The enrichment of blood with oxygen occurs in the lungs, and the saturation of nutrients - the digestive organs. Neutralization and elimination of metabolic products occurs in the liver and kidneys. The blood circulation is regulated by hormones and the autonomic nervous system. There are small (through the lungs) and large (through the organs and tissues) circles of blood circulation.
The cardiovascular system is a system of organs that circulates blood in the human body and animals. Owing 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 removed. The circulation of blood in the cardiovascular system in vertebrate animals and humans is supplemented by lymphatic drainage from organs and tissues of the body through the system of vessels, nodes and ducts of the lymphatic system, which flow into the venous system at the confluence of the subclavian veins. The composition of the cardiovascular system includes the heart - the organ that causes the blood to move, pumping it into the blood vessels - the hollow tubes of various caliber through which it circulates. All functions of the circulatory system are strictly coordinated due to the neuro-reflex regulation, which allows maintaining homeostasis in the conditions of constantly changing external and internal environment.
Blood vessels are elastic tubular formations in the body of animals and humans, through which a rhythmically contracted heart or pulsating vessel is used to move blood through the body: to organs and tissues through arteries, arterioles, arterial capillaries, and from them to the heart - through venous capillaries, venules and veins.
What are the vessels in the body?
We will not delve into the anatomical details, only outline the main features of each type of blood vessels. So, in the body there are:
- Arteries. These vessels have the largest cross-section and are considered trunk. According to him, the blood enriched with oxygen enters all cells. The walls of the arteries are elastic and elastic: this is necessary to ensure uninterrupted blood flow. In these vessels the speed of blood flow is maximum, so 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 the outflow of blood containing carbon dioxide and various metabolic products. Thanks to them, cells are also freed from toxins. The 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 prevent blood flow. This is necessary when part of the blood must be deposited with the redistribution of blood flow.
- Capillaries They are the final branches of the arterial and venous channels. Thin and small capillaries fit directly into the 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. During the day about 85,000 liters of blood pass through them.
- Lymphatic vessels. This type of blood vessel 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 differ in diameter, and in the largest of them there are valves on the walls (as in the veins) that prevent the flow of fluid back. The walls of the lymphatic vessels are soft, since the 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 transport of oxygen, carbon dioxide and biologically active substances.
What can 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 outside.
But there are situations when various pathological processes thin the vascular wall, make it less elastic, fragile. This can lead to numerous adverse effects.
For example, a vessel can rupture from too much pressure of blood flowing through it. Most often this occurs with arteries. If the vessel is damaged, it causes 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 the femoral artery, ruptures, the bleeding will be very strong. If blood is not stopped, a person will die in a matter of minutes. At the same time, it does not matter where the “leakage” happens: in any case, the risk of death is very high.
If a small vessel or capillary burst, the situation can develop in two ways. When a vessel is torn in the body, a well-known phenomenon appears to us all - a bruise. It represents blood that has accumulated in the subcutaneous tissues. As a rule, such damages are not dangerous and pass by themselves when the vascular wall is restored.
The situation is much worse if a small vessel breaks in the brain. Cells of the nervous system, and the brain, including very sensitive. Even a small amount of spilled blood leads to their death. This is what happens in hemorrhagic strokes and hematomas in the brain. That part of the brain into which blood has fallen 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 the previous level of development.
Not only arteries, but also veins can be affected. They almost never break, because the speed of blood flow in them is much less 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 thinning of their walls, so an increased load (for example, during vomiting) can lead to rupture of the veins and the occurrence of extensive internal bleeding.
In order to avoid all these unpleasant and potentially life-threatening consequences, it is necessary to maintain the health of the vessels and take care of them throughout their lives.
How to detect problems with blood vessels?
To understand that your vessels need help, it is not necessary to wait for the vivid manifestations of their pathology. There are signs that can be noticed much earlier:
- frequent headaches and dizziness;
- fatigue, weakness, apathy;
- ripples and glimpses of "flies" before the eyes;
- poor sleep;
- shortness of breath even with little exertion;
- feeling of heaviness and pressure in the heart;
- drowsiness and lethargy during the day, even if you slept the night before;
- 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;
- spasms of the limbs;
If one or more of these symptoms periodically bother you, you need to urgently begin preventive measures.
How to care for vessels?
In order to preserve 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 diseases is a douche. Warm water will expand the vessels, and cold water, on the contrary, will narrow them. Such training will preserve the elasticity of the vascular wall. In addition, the procedure improves metabolism and gas exchange. The optimal time for a douche is morning. Start the procedure with warm water, and then increase its temperature to a limit that you can tolerate. After that, go to the cold water, lowering its degree. Repeat alternation 5 - 6 times. Complete the procedure with cool water.
No less important role in the prevention of vascular diseases is proper nutrition. It is necessary to add to the diet foods rich in vitamins C and PP, as well as potassium. These substances are sufficiently found in cabbage, carrots, bell peppers, radishes, beets, apples, citrus fruits, bananas and other fruits and vegetables. Fresh greens and buckwheat are also useful.
Physical exercise also supports the walls of blood vessels in a tone. Every morning, do exercises at a quiet pace, without overloading yourself. Walk more, go swimming whenever possible. Cardiovascular training on a treadmill and bicycle trainer gives a good effect. But they are not suitable for everyone, so before starting classes, it is necessary to consult a cardiologist.
Massage helps to improve the condition of the vessels. Regularly knead the limbs at home, but do not push the skin too hard, otherwise you may damage the blood vessels. Remember! With varicose veins and thrombosis, massage is contraindicated.
All these procedures will bring a good effect only if they are carried out regularly. Another condition for success - a complete rejection of bad habits. Otherwise, smoking and alcohol abuse can negate all your efforts to strengthen the blood vessels.
Take care of your vessels - and they will serve you for a very long time .
