Why is the kidney easy to be damaged?

It is to do with its structure and function.
Each kidney has about 1.3 million glomerulus, which filters out about 180 liters of urine a day, resulting in about 1.8 liters of urine. The kidneys regulate the amount of urine and maintain the balance of water in the body.
Kidney is an important endocrine organ, it can produce a variety of hormones and biological active substances, to the human body blood pressure, water and electrolyte balance, erythropoiesis, calcium and phosphorus metabolism plays an important role in many aspects.
The kidneys produce a kind of erythropoietin. Erythropoietin promotes bone marrow hematopoiesis and produces red blood cells. So when the kidney is sick, the erythropoietin produces less, and Anemia occurs. In addition, the kidneys can turn the active vitamin D precursor into active vitamin D, which regulates the metabolism of calcium and phosphorus in the body.
Why is the kidney easy to be damaged?
The waste from the metabolism, the kidneys are required to discharge the waste out of the body to maintain normal physiological activity. Water and salt balance, in addition, because of the need to maintain and remove metabolic wastes, so the heart blood elimination, about one fifth through the kidneys, and once when the blood containing bacterium or toxic substances, or is the metabolic waste more than kidney can bear load, tends to be damage to kidney damage.
Meanwhile, because the kidney is very sensitive to changes of blood pressure, ischemia, so the human body appears relatively large blood pressure fluctuation, or acute blood loss, also can cause injury to the kidney.
