How Do Our Kidneys Work

Why Is Kidney Important?
The function of the kidney play an important role in how our body operats.The kidney is the organ that filters blood and produces urine and they also regulate amounts of certain vital substances in the body. Is there other function? Following part will tell us an unexpected answer.
There are a number of conditions,diseases and lifestyle choices that can lead to decreased kindney function. Kidney diseases affect the life of the patient seriously. In order to protect our kidney well, let’s learn the basic knowledge of the kidney carefully.
Structure of the kidneys
The kidney is responsible for maintaining fluid balance within the body. Unfiltered blood enters the kidneys through the renal artery. The kidneys take metabolites and minerals away from the blood in the section which is called the nephron. The nephron is the basic structure and function unit of the kidneys.Each nephron is made of renal corpuscle and kidney tubules, which can filter wastes, macromolecules, and ions from the blood to urine. About 1 million nephrons in each kidney form 10-20 cone-shaped units which is called renal pyramids that span both the inner medulla and outer cortex portions of the kidney.
All of the tubules from the many nephrons pool together into one collection duct. In the collection duct, many substances are reabsorbed back into the blood, helping to regulate electrolytes.
The function of the kidneys
Filtering of the blood is the major responsibility of the kidney.this function can clean our blood through taking wastes away from our blood in the part called the nephron.
The kidneys are important in keeping homeostasis. This is involved in regulating electrolytes, blood pressure and the PH level of blood. The kidney can secrete rennin which can regulate our blood by the RAAS system. Erythropoietin, a protein that motivates the production of the red blood cell, is secreted by the kidney. The kidney tubules can filter wastes, macromolecules, and ions from the blood to urine. At the same time, they also conserve water,salts,and electrolytes which is useful to our body to keep the balance of the internal environment. The kidney also can regulate the balance of calcium and Phosphorous by activating VD3.
In a word, all the functions contributes to building a stable internal environment,which is the necessary condition to maintain our normal life.
Our kidneys have so many functions. Once the kidney is damaged ,all the functions will be weaken or lost. Then our body will be in morbidity.
The development process of the kidney disease are more secretive, but in the early stage of chronic renal disease, the body will appear warning signs/ symptoms/clinical manifestation/ clinical behavior, such as drowsiness, fatigue, face yellow, loss of appetite. These symptoms appear on many people but they are ignored.So the condition of many patients who come to hospital for help has been developed to kidney failure.
Protecting our kidneys is to protect our body.Let’s have a close attention on kidney disease and our health.
