The kidneys are two bean-shaped organs located in the lower back, one on each side of the spine. They play a crucial role in filtering waste and excess fluids from the blood, producing urine. This process helps maintain a balance of minerals and electrolytes in the body, which is essential for overall health. In addition to filtering blood, the kidneys also help regulate blood pressure and produce hormones that support red blood cell production. Keeping the kidneys healthy is important, as they perform vital functions that affect many other systems in the body. Drinking enough water and eating a balanced diet can help support their health.
