Renal-Related Acidosis

Triangular regions in the kidney’s medulla, containing tubules and blood vessels that help concentrate urine.  A condition where the body fluids contain too much acid, leading to an imbalance in pH levels.

Pathophysiology

Structure:

• Renal Pyramids: Composed of nephrons, the functional units of the kidney, responsible for filtering blood and excreting waste.

Blood Supply:

• Renal Arteries: Supply oxygen-rich blood to the kidneys.
• Vasa Recta: Tiny blood vessels in the pyramids that help maintain the kidney’s concentration gradient.

Nerve Supply:

• Sympathetic Nervous System: Regulates blood flow and filtration rate in the kidneys.

Acidosis Mechanism:

• When kidneys fail to excrete enough acid or reabsorb enough bicarbonate, acid builds up, leading to acidosis.

Types of Acidosis

1. Metabolic Acidosis: Excess acid or loss of bicarbonate.
2. Respiratory Acidosis: Impaired lung function leading to CO₂ retention.
3. Renal Tubular Acidosis: Kidneys fail to excrete acids properly.
