Our circulatory system is a complex network that allows clean and nutrient-filled blood to travel through our body, feeding each organ, while oxygen-depleted and somewhat dirty blood is transported to be purified again. Throughout this procedure the veins, arteries and capillaries They play a very important role, helping the whole gear to work effectively to guarantee our well-being.
You ask yourself what is the function of the veins? Keep reading because in this oneHOWTO article we explain it to you in detail.
The vein function in our circulatory system it is of great importance, since they are in charge of transporting blood from the organs and tissues to the left atrium of our heart.
The cardiac organ is in charge of pumping oxygenated and nutrient-rich blood through our body, a process that is carried out through the arteries. When nutrient-rich blood is conducted through the arteries, it oxygenates and nourishes the capillaries and, at the same time, all the waste from the tissues passes to the veins, in charge of distributing them to the different organs responsible for their elimination. .
The veins carry blood that has already been used by the tissues and organs and that, therefore, has run out of oxygen, this is the reason why it is thicker because it is loaded with carbon dioxide and waste product of the nutrient combustion process. The veins are also responsible for distributing the blood full of waste to each of the organs responsible for its elimination:
- The lungs, responsible for eliminating carbon dioxide.
- The kidneys, which will remove sodium, calcium, potassium, magnesium, urea, ammonium, and bicarbonate.
- The liver, which, thanks to the bile, will be able to eliminate waste such as the remaining bilirubin.
This procedure is essential for our health, since it is as important that the oxygen-filled blood circulates properly through our arteries as it is conducted through the veins to those organs in charge of cleaning them. The correct balance of this task guarantees our well-being.
While the arteries are deep and cannot be seen with the naked eye, the veins are more superficial, which is why we can not only appreciate them in some areas such as the forearm or wrists, but through them samples of blood that allow us to evaluate our state of health when performing a blood test.
Some of the common diseases that can affect the veins are:
- Varicose veins: It occurs when the veins dilate and become unable to return blood to the heart, causing visible inflammation in the area, pain, discomfort and circulatory problems. Some habits can promote their appearance, so in our article how to avoid varicose veins we give you recommendations to prevent them.
- Deep venous thrombosis: manifests when a clot forms in a deep vein in our body, a condition that must be treated as soon as possible to avoid complications.
- Varicocele: This condition causes inflammation in the scrotum area that occurs when the veins dilate and become varicose, causing blood to return through the walls of the veins in the testicular area. In our article what are the symptoms of varicocele you will find more information about it.
- Phlebitis: inflammation of the wall of a vein.
- Buerger’s disease: it is an inflammation in the small veins of the extremities that occurs in smokers.
Any of these conditions must be diagnosed and cared for by a specialist to ensure a better quality of life.
