riñones

Riñones, also known as kidneys, are bean-shaped organs that are part of the urinary system. Humans typically have two kidneys, located on either side of the spine, below the ribs and behind the belly. Their primary function is to filter waste products and excess water from the blood, producing urine. This process is crucial for maintaining the body's fluid and electrolyte balance, regulating blood pressure, and producing hormones that stimulate red blood cell production and promote bone health.

Each kidney contains millions of microscopic filtering units called nephrons. Blood enters the kidney and is filtered in these nephrons, where waste materials, salts, and water are extracted. The useful substances are reabsorbed back into the bloodstream, while the waste and excess water form urine, which then travels down the ureters to the bladder for storage before being expelled from the body.

Kidney health is vital for overall well-being. Conditions such as kidney stones, infections, and chronic kidney disease can impair their function, leading to serious health complications. Maintaining a healthy lifestyle, including a balanced diet, adequate hydration, and regular exercise, is important for supporting kidney function. Prompt medical attention is recommended if symptoms suggestive of kidney problems arise, such as changes in urination, swelling, or fatigue.
