Ernieren

Ernieren is a German term that translates to "kidney" in English. The kidneys are vital organs in the human body, responsible for filtering waste products from the blood and producing urine. They play a crucial role in maintaining fluid balance, regulating blood pressure, and producing hormones essential for red blood cell production and bone health.

The kidneys are bean-shaped organs located on either side of the spine, below the ribs and behind the belly. Each kidney is approximately the size of a fist. They are composed of millions of tiny filtering units called nephrons. Each nephron consists of a glomerulus, a small network of capillaries, and a tubule. Blood enters the glomerulus, where waste products and excess fluid are filtered out. The remaining fluid and essential substances are reabsorbed back into the bloodstream, while the waste products form urine, which travels down the ureters to the bladder for storage and eventual excretion.

Disorders affecting the kidneys are collectively known as kidney disease or renal disease. These conditions can impair the kidneys' ability to perform their essential functions, leading to a range of health problems. Common kidney diseases include chronic kidney disease (CKD), kidney stones, and kidney infections. Early detection and management are crucial for preserving kidney function and preventing more severe complications. Medical professionals specializing in kidney health are called nephrologists.
