Acute tubular necrosis is the death of tubular cells in which organ?

Explanation:
Acute tubular necrosis refers to death of the tubular epithelial cells inside the kidney’s nephrons. It occurs mainly when the kidney’s tubules don’t receive enough blood flow (ischemia) or when toxins injure the tubule cells, with the proximal tubule and thick ascending limb being particularly vulnerable. When these cells die, the tubules can’t reabsorb or secrete properly, leading to decreased urine output and impaired kidney function. The liver, heart, and brain have different structures and are not the sites of this specific tubular-cell death, which is why the kidney is the correct organ.
