I wonder about the kidneys
The norm is the fact that the left kidney is several centimeters higher than the right one.
A kidney is similar in size to the size of an individual's fist. The kidneys of a newborn, in relation to the total weight of his body, are 3 times larger than the kidneys of an adult.
The kidneys are a blood filter. They purify the body's liquid environment from human waste.
The structural and functional components of the kidneys are about one million nephrons. These filters are responsible for the rate of urine formation and for its qualitative composition. After 40 years, about 1% of nephrons die, but the remaining ones do an excellent job with their assigned function.
During the day, the kidneys produce from 150 to 180 liters of urine, called primary, due to filtration. In terms of its qualitative composition, it is almost identical to blood plasma. In subsequent processes, 1-1.5 liters of so-called secondary (final) urine is obtained, which is excreted from the body through the urinary tract.
About a liter of blood enters the kidneys every minute. Of this amount, 1 ml accumulates in the pelvis in the form of urine. The remaining amount of blood flows back into the bloodstream in a purified form.
The kidneys are responsible for the balance of amino acids and electrolytes in human blood.
In the human body, these bean-shaped organs are responsible for maintaining a constant volume of fluid. 5-6 liters of blood constantly circulates in the body of the average inhabitant of the Earth (with a weight of 70 kg). This volume of blood is filtered by the kidneys 35-50 times per day.
The kidneys are regulators of blood pressure. When the pressure decreases, they signal the rest of the organs and body systems about the narrowing of blood vessels. As a result, the pressure increases. As a result, the kidneys provide a full blood supply to all parts of the human body. In addition, the kidneys synthesize the hormone renin, which is a regulator of blood pressure.
The kidneys synthesize the substance erythropoietin, which stimulates the formation of red blood cells - erythrocytes. Their main function is to deliver oxygen to tissues and organ systems, as well as eliminate the accumulation of carbon dioxide in organs. Therefore, the kidneys are rightfully considered indicators of sufficient oxygen in the body.
The kidneys produce the active form of the antirachitic vitamin D.
The kidneys can be called long-lived organs. They lose their functional ability only if 70-75% of the nephrons die.
