Elimination

Elimination (from Latin eliminatio - exclusion, elimination) is the process of removing various substances, metabolic products or other components from the body. In physiology, elimination refers to the process of removing waste products (such as metabolites, toxins, and other waste products) from the blood by the kidneys, which play an important role in maintaining homeostasis in the body.

Kidneys are organs that remove waste products from the body through the blood. They function continuously, maintaining homeostasis and ensuring the normal functioning of all organs and systems. During the elimination process, the kidneys remove metabolic products from the blood, such as urea, creatinine, ammonia and others.

The elimination process begins with blood filtration in the kidneys, where most molecules and particles such as glucose, amino acids and electrolytes are removed. Then reabsorption (reabsorption) of certain substances occurs back into the blood, which allows you to maintain the necessary components in the body and ensure their balance.

However, elimination is not a completely effective process as some substances, such as toxins, drugs and other chemicals, can accumulate in the body and cause various diseases and health problems. Therefore, elimination control and regulation are important aspects of human health and well-being.

In addition, elimination may be impaired in various kidney diseases, such as renal failure, nephrotic syndrome, and others. In such cases, additional therapy may be required to improve the elimination process.

Thus, elimination is an important process that ensures the maintenance of homeostasis and normal functioning of the body. Controlling elimination is important to human health, and additional treatment may be required to improve this process if necessary.

Elimination (from the Latin eliminatio - removal, elimination) is a term that is used in various fields of science and technology to describe the process of removing or eliminating something. In physiology, elimination refers to the process of removing waste products from the body's blood by the kidneys. This process plays an important role in maintaining human health and is one of the key factors determining life expectancy.

In the human body, the kidneys play the role of a filter that removes metabolic products from the blood, such as urea, creatinine, uric acid and others. These products are the result of processes occurring in the body's tissues and must be removed from the blood to avoid their accumulation in the body and cause various diseases.

The elimination process begins with the filtration of the blood through the kidneys, where water and solutes are removed. These substances then enter the bladder, where they are concentrated and form urine. Urine is eliminated from the body through the urethra.

Elimination also plays an important role in the body's metabolism. When waste products are eliminated from the body, it allows the body to receive the nutrients and energy it needs. In addition, the elimination process helps maintain fluid balance in the body, which is especially important for people suffering from kidney disease.

However, if the elimination process is disrupted, it can lead to various diseases and health problems. For example, kidney failure can lead to the accumulation of metabolic waste products in the blood and tissues, which can cause various complications such as anemia, edema and other problems.

Thus, elimination is an important process that plays a key role in maintaining human health and well-being. Understanding this process and its mechanisms can help people stay healthy and prevent various diseases associated with impaired elimination.

Elimination: elimination theory

Elimination in biology is the process of releasing any substances (metabolites, hormones) by a physiologically or pathologically altered cell or tissue; therefore, it is a cell-membrane process of excretion of a product or mediator absorbed by cells, which is the fruit of the metabolic process in this cell. In physiology, these processes are studied by the method of leukocyte hemosorption. When the embryo is mechanically fragmented into cells, the elimination process begins to manifest itself from the 15th hour of development. In each cell of the body there are new organisms, which predetermines the inclusion of elimination mechanisms and metabolic processes during the development of new cells. The development of all cells occurs cyclically according to a physiological principle. The principle of elimination is a special case of the more general concept of blood purification (toxins, metabolites). One of the methods for studying elimination (in particular, to determine the external elimination sector) is the use of radioactive tracers. If particles absorbed by red blood cells are a substrate for the elimination process, then the radioactive tracer will be released as radioactive contamination. The resulting radioisotope-hemoglobin complex is excreted in the urine. The lower the filtration volume, the less radioactive isotope will be in the urine. This principle was applied by doctors in practice: patients with a filtration volume of less than 30 ml/hour had to receive erythropoietin intravenously, as they showed signs of azotemia. Erythropoietins. Erythropoietin products of resorption action released in the amniotic fluid stimulate fetal erythropoiesis and contribute to an increase in hemoglobin and erythritol in the blood of the pregnant woman. Eliminated methemoglobin containing protein breakdown products are excreted from the kidney
