Kidney is like a blood scavenger, each body has two kidneys. Its shape is similar to the beans, symmetrical distribution in the human body, which are on both sides of the spine after the middle of the body and parallel with the waist.

The function of the kidney

1.Filter the blood

The kidneys can remove the metabolic wastes and excess liquid which are collected when the blood flows through the body. Every day, about 190 liters of blood enters the kidneys through the renal artery. There are millions of small filters (glomeruli) in the kidney that filter out waste and water from the blood.

Most of the substances we do not want are from the diet, the kidneys will remove a certain amount of salt and other minerals from the blood automatically, leaving the amount just to meet the needs of the body. The cleared blood returns to the heart and recirculates through the body again. Excessive waste and liquid will be discharged from the kidneys in the form of urine. Most people urinate about 2 liters of urine per day.

2.Balance the level of the liquid

The healthy kidneys maintain the body's fluid balance by removing excess fluid from the body. Usually, the liquid content of women is about 55% of the total body weight, while men maintain about 60% of the total body weight. The kidneys maintain this proportion by balancing the relationship between the amount of fluid discharged from the body and the amount of fluid entering the body.

The liquid that enters our body includes drinks and high liquid foods (such as soups) that we drink and so on. If we drink a lot of liquid, healthy kidneys can remove the excess parts, them we will urinate a lot of urine. If we drink less liquid, the kidneys will keep the liquid.

Liquid can also be discharged from the body through sweat, breathing and feces. If the weather is hot, we can sweat a lot of liquid, so the kidneys will not discharge many urine.

With the exhaustion of renal function, it becomes more and more difficult to maintain this balance, the patient will appear the symptom of fluid excess. In order to maintain the liquid balance, we need to pay attention to the type of diet and liquid intake.
