Following are the main functions of kidney:
1. Blood purification
Kidney is continuously employed and excretes unnecessary toxic substances formed in the body through urine.
2. Discharge of waste products
The most important function of the kidney is to purify the blood by removing waste products. The food we take contains protein. This protein is essential for keeping the body healthy and for the development of the body. Protein is used by the body but in this process some waste material is produced. The accumulation of these waste materials is similar to maintaining poison inside our body. Our kidneys filter and purify toxic waste products from the blood. These toxins eventually dissipate with urine.
Creatinine and urea are two important waste products. Observations of their volume in the blood indicate kidney function. When both kidneys are impaired, the amount of creatinine and urea are elevated to a higher level in the blood test.
3. Balance of water in the body
The kidneys excrete excess water by passing urine keeping the amount of water required for the body.
When the kidneys go bad, they lose the ability to exclude this excess water from the body, causing the body to swell due to the accumulation of excess water.
4. Balance of acid and alkali
Kidney works by keeping the amount of sodium, potassium, chloride, magnesium, phosphorus, bicarbonate, etc. in the body unchanged. The above substances are responsible for the amount of acid and alkali in the body. Increasing or decreasing the amount of sodium can have serious effects on the brain and heart and muscle activity by increasing or decreasing the amount of potassium.
Keeping calcium and phosphorus appropriate and keeping their levels normal is essential for healthy bones and healthy teeth in our body.
5. Blood pressure control
Kidney makes many hormones such as angiotensin, aldosterone, prostaglandin etc. With the help of these hormones, the body maintains a balance of water, acids and alkalis. With the help of this balance, the kidneys work to maintain normal blood pressure in the body. In case of kidney failure, production of hormones and disturbances in salt and water balance leads to high blood pressure.
6. Assist in the production of blood particles
Red blood vessels present in the blood are produced in the bone marrow with the help of erythropoietin. Erythropoietin is made in the kidney. In the event of kidney failure, this substance stops producing little or no at all, which reduces the production of red blood cells and causes blood fade, which is called anemia (anemia). it is said.
7. Strengthening bones
To maintain healthy bones, the kidney converts vitamin D into an active form that is necessary for the absorption of calcium from food, the growth of bones and teeth, and to keep bones strong and healthy.
