Urinary Bladder Anatomy And Physiology In Hindi | Functions | Blood Supply | Structure

Welcome to our comprehensive guide on the Urinary Bladder. This video is designed for medical, nursing, and paramedical students who want a clear, step-by-step understanding of the human excretory system. We cover everything from the basic structure to the complex process of voiding (micturition), fully explained in Hindi.

​In this video, we cover:
​Anatomy and Physiology: A deep dive into the location, shape, and function of the bladder within the pelvic cavity.
​Organ Sequence: How the bladder fits into the urinary tract, connecting the ureters to the urethra.
​Blood Supply: Understanding the arterial supply and venous drainage that keeps the bladder functioning.
​Surfaces & Borders: A detailed look at the superior, inferolateral, and posterior surfaces.
​Layers of the Urinary Bladder: Breakdown of the four main layers: Mucosa, Submucosa, Muscularis (Detrusor muscle), and the Serosa/Adventitia.

​Sphincters: The role of the Internal and External urethral sphincters in controlling urine flow.
​The Trigone: Why this smooth triangular region is clinically significant and how it differs from the rest of the bladder wall.
​Voiding (Micturition): The physiological process and nervous system control behind urination.
​Key Highlights from the Diagram:

​Detrusor Muscle: The powerful muscle responsible for contracting to expel urine.
​Rugae: The folds in the bladder wall that allow it to expand as it fills.
​Ureteral Orifices: The entry points where urine enters from the kidneys.
​Internal Urethral Sphincter: Located at the bladder neck (involuntary control).
​Prostate (Males only): Showing the relationship between the bladder and the prostate gland in the male anatomy.
