Cortical Nephron Fibrosis

Cortical nephron chronic? injury or inflammation. সহজ বাংলা: অতিরিক্ত দাগের মতো টিস্যু তৈরি হওয়া।" data-rx-term="fibrosis" data-rx-definition="Fibrosis means excess scar-like tissue formation after chronic injury or inflammation. সহজ বাংলা: অতিরিক্ত দাগের মতো টিস্যু তৈরি হওয়া।">fibrosis? involves the development of scar tissue in the cortex area of the nephrons within the kidneys. The cortex is the outer layer of the kidney where essential functions like filtering blood and removing waste occur. When fibrosis happens, it disrupts these processes, potentially leading to chronic kidney disease (CKD) and kidney failure?.

Pathophysiology

Structure

• Nephron Anatomy: Each nephron consists of the renal? corpuscle (including the glomerulus) and the renal tubule, located primarily in the cortex.
• Cortex Function: The cortex filters blood, reabsorbs essential substances, and secretes waste into the urine.

Blood Supply

• Renal? Artery: Supplies oxygen-rich blood to the kidneys.
• Afferent and Efferent Arterioles: Branch from the renal? artery to deliver blood to the glomeruli and carry it away after filtration.

Nerve Supply

• Autonomic Nervous System: Regulates blood flow and filtration rate.
• Sensory Nerves: Detect pain? and other sensations within the kidney.
