System Fundamentals
"The heart is the only organ that works 24/7 without rest. Understanding its mechanics is the foundation of acute nursing care."
The kidneys are vital organs that filter ~180 L of blood per day, producing 1–2 L of urine. Beyond excretion, they regulate fluid-electrolyte and acid-base balance, synthesize erythropoietin and renin, and activate vitamin D.
