Blood - Main Element

Blood plays an important role in our body, performing many functions necessary to maintain life. It is the main element of blood circulation, which not only ensures the transport of oxygen and nutrients to cells, but also removes harmful substances formed during the metabolic process.

Blood consists of plasma and cellular elements, including red blood cells, white blood cells and platelets. Red blood cells contain hemoglobin, which binds oxygen and carries it to tissue cells, and then returns carbon dioxide to the lungs for removal from the body. White blood cells play an important role in the immune system, protecting the body from infections and diseases, while platelets are involved in the blood clotting process, preventing bleeding.

Blood also performs the function of thermoregulation, transferring heat from internal organs to the surface of the body, where it is released to the environment. In addition, blood contains hormones and other biologically active substances that regulate many processes in the body.

However, one of the most important functions of the blood is to cleanse the body of harmful substances formed during the metabolic process. Carbohydrates and fats, for example, are converted into carbon dioxide and water, and proteins into nitrogen, phosphorus, sulfur and other breakdown products. The ammonia and salts produced by this process can accumulate in the body and cause serious illness. The kidneys do the job of removing these harmful substances from the blood. Blood enters the kidneys through the renal arteries and passes through a network of blood capillaries to the nephrons of each kidney, which cleanse the blood by removing excess water, salt, urea and other waste products, which are then excreted from the body in the form of urine.

Purified blood returns to the heart through the inferior vena cava, where it is again enriched with oxygen and a new circulatory cycle occurs.

Thus, blood plays an important role in the life of the body, providing transportation of oxygen and nutrients, protection against infections and diseases, thermoregulation and cleansing the body of harmful substances. Therefore, to maintain your health, it is important to monitor the condition of your blood and take measures to maintain it.
