Each kidney contains around 1 million nephrons, the functional units that perform ultrafiltration of plasma, leading to urine formation. Renal physiology begins with understanding the renal blood flow, which is about 25% of cardiac output, making the kidneys one of the most highly perfused organs in the body 🩸. The kidneys perform several essential functions: regulation of fluid and electrolyte balance, acid-base balance, excretion of metabolic waste products (like urea and creatinine), and hormonal functions — including secretion of erythropoietin, renin, and activation of vitamin D (calcitriol) ☀️. Additionally, they play a critical role in blood pressure regulation via the renin-angiotensin-aldosterone system (RAAS). Anatomically, each kidney is composed of an outer cortex and an inner medulla, with the renal pyramids draining into the renal pelvis and ultimately the ureters. This introduction lays the foundation for exploring glomerular filtration, tubular reabsorption, secretion, and the sophisticated control systems that maintain body fluid balance, making renal physiology a cornerstone of internal medicine and clinical diagnostics 🧠🩺. #RenalPhysiology #KidneyFunction #DrSreeTeja #NEETPG #FMGE #USMLEStep1 #MedicalEducation #InternalMedicine #NephrologyBasics #MBBS #UrineFormation #Homeostasis #RAAS #MedicalYouTube #DoctorLecture #AnatomyAndPhysiology
