The Role of Kidneys in Our Life

The kidneys filter about 120 to 150 quarts of blood daily, removing waste and excess fluids. These bean-shaped organs help regulate electrolyte levels, control blood pressure, and manage the production of red blood cells. Additionally, they play a crucial role in maintaining a stable internal environment, which is essential for the proper functioning of all body systems.

Main Parts of the Kidney

Understanding the structure of the kidneys helps us appreciate how they function. Here are the primary parts:

1. Renal Cortex: The outer layer of the kidney that contains nephrons, the filtering units.
2. Renal Medulla: Beneath the cortex, it contains renal pyramids that transport urine to the renal pelvis.
3. Renal Pelvis: The innermost part that collects urine before it enters the ureter.
4. Nephrons: The functional units that filter blood, remove waste, and form urine.

How Kidneys Work: The Filtration Process

The kidneys perform their duties through a complex process involving multiple steps:

1. Filtration: Blood enters the nephrons where waste products and excess substances are filtered out.
2. Reabsorption: Essential substances like water, glucose, and electrolytes are reabsorbed back into the bloodstream.
3. Secretion: Additional waste and substances, such as excess ions and drugs, are secreted into the urine.
4. Urine Formation: Processed waste forms urine, which is collected in the renal pelvis and transported to the bladder.
5. Excretion: Urine is stored in the bladder and expelled from the body through the urethra.
