The kidneys are two bean-shaped organs located on either side of the spine, below the ribs. They are a crucial part of the urinary system and play a vital role in maintaining the body's overall health and function.
Functions of the Kidneys:
Filtration: The kidneys filter waste and excess substances, such as water, salts, and toxins, from the blood to form urine.
Regulation of Fluid and Electrolyte Balance: The kidneys help regulate the body's fluid and electrolyte balance by adjusting the amount of water and salts excreted in the urine.
Acid-Base Balance: They help maintain the body's acid-base balance by controlling the levels of acids and bases in the blood.
Kidney Stones: Hard deposits of minerals and salts that form in the kidneys and can cause severe pain when passing through the urinary tract.
Kidney Infections: Bacterial infections that can causeinflammation and damage to the kidneys if left untreated.
Chronic Kidney Disease: A long-term condition where the kidneys gradually lose function over time, often due to conditions like diabetes or high bloodpressure.
