Answer 1

Answer:

The kidney produce urine by removing toxic waste products and excess water from the body. Urine formed in each kidney passes through the ureter, flows into bladder before finally being excreted through the urethra.

Function

The primary function of the kidney is to make urine and purify the blood. Each kidney removes waste materials, and other chemicals which are not required by the body. Most important functions of the kidney are described below.

Removal of waste product

• Purification of blood by removal of waste products is the most important function of the kidney.

The food that we consume contains protein. Protein is necessary for the growth and repair of the body. But as protein is utilized by the body it produces waste products. Accumulation and retention of these waste products is similar to retaining poison inside the body. Each kidney filters blood, and toxic waste products which are eventually excreted in the urine.

• Creatinine and urea are two important waste products that can easily be measured in the blood. Their “values” in blood tests reflects the function of the kidney. When both the kidneys fail, value of creatinine and urea will be high in blood test.

Removal of excess fluid

1. The second most important function of the kidney is the regulation of fluid balance by excreting excess amount of water as urine while retaining the necessary amount of water in the body, that is essential for living .When the kidneys, fail they lose the ability of removing this excess amount of water. Excess water in the body leads to swelling.
