We do not know until the end of all the functions of all organs.The kidney, too, is not as simple as they seem.Although the main function of the kidneys known.Some of them even know the people far from medicine, with other well acquainted only students - future doctors, biologists and veterinarians.Structure and function of the kidneys are studied in detail in the respective departments.We will focus mainly on the functions.
not best known function of the kidneys is to maintain a constant normal blood acidity.Of course, the body responsible for such a complex process not only the kidneys.Also part of the task falls on the light.Recent "Veda" delivery into the blood stream of carbon dioxide.But the kidneys reabsorb bicarbonate from urine and secrete hydrogen ions into the urine, so reducing the acidity of the blood.
also not every day we hear of such a function of the kidneys, the regulation of plasma osmolality.Quietly, in the dark they are doing a serious job of keeping the amount of electrolytes in the blood of normal."The immediate supervisor" in this specialty at the kidney - the hypothalamus.He is able to see an increase in electrolytes in the blood and give a signal to the pituitary gland.As a result of ejected antidiuretic hormone that causes the kidneys to make the urine more concentrated, not bringing a lot of water in the urine.Thus, the electrolytes are displayed, and the water remains higher.As a result, the ratio of solute and water - the solvent once again becomes normal.Antidiuretic hormone is able to do some parts of the nephron more permeable to water, and it comes back into filtered blood.
also important function of the kidneys in blood pressure regulation.Yes, they are doing this and that.Long-term regulation of the parameters of pressure - it is the kidney.This important function of the kidneys in humans has recently been given much attention by cardiologists as cardiovascular disease - the main "killer" relatively young people.Returning to the regulatory function of the kidneys.In practice it is realized by the synthesis of renin, which affects how many molecules of sodium chloride contained in the blood.In this process involves hormones such as angiotensin and aldosterone, and the scheme of their actions is very complicated.However, eventually it regulated blood plasma volume, which affects blood pressure.That is why the "cores" drinking diuretics, however, necessarily be appointed by the potassium-sparing drugs, as diuretics often do not distinguish between the electrolytes, and without enough potassium heart is bad.
also very interesting function is the synthesis of the hormone erythropoietin.Especially interested in this hormone athletes.The fact is that thanks to this hormone increases the amount of oxygen carriers - gemoglobinsoderzhaschih erythrocytes.If the kidneys are not enough oxygen - they start to stimulate the production of red blood cells.So every time you do not have enough oxygen in training, your kidneys begin to synthesize erythropoietin, and after a while there comes the effect of exercise - increase the number of oxygen carriers.
and complete our review function of the output of waste, in fact, the most important function of the kidneys.We need protein for life, but the products of its metabolism - the most powerful poisons.Partially withdraw their intestines, but a lot gets and the share of the kidneys.They - workers purity, tireless workers who make our normal internal environment for proper life.That the implementation of this feature are subject to the laws of the nephron devices - functional unit of inner purity.The process of releasing blood from the "filth" two-step, first filtered almost all of the then returned to the blood.And at each stage there are complicated regulatory mechanisms.
regular urine tests - minimum measures we can take to determine the state of the kidneys.You do not need to disregard the health of these young workers.
