Anatomy and Structure
bean-shaped structure
enclosed within a tough, fibrous capsule. Internally, the kidney is divided into several regions:
Cortex:
the outer layer, containing the glomeruli and blood vessels.
Medulla:
the inner layer, containing the renal pyramids and collecting ducts.
Renal Pelvis:
the funnel-shaped structure that collects urine from the renal pyramids and leads to the ureter.
Key Functions of the Kidney
Filtration:
Removing waste products and toxins from the blood. This process occurs in the glomeruli.
Reabsorption:
Returning essential substances like glucose, amino acids, and water back into the bloodstream.
Secretion:
Actively eliminating waste products, drugs, and other substances from the blood.
Regulation of Blood Pressure:
Controlling blood pressure through the renin-angiotensin-aldosterone system (RAAS).
Electrolyte Balance:
Maintaining the proper balance of electrolytes, such as sodium, potassium, and calcium.
Erythropoiesis:
Producing erythropoietin, a hormone that stimulates red blood cell production.
