Final answer:
When the kidneys fail, all body systems are affected, leading to various symptoms and complications.
Step-by-step explanation:
With sudden cessation of renal function, all body systems are affected by the inability to maintain fluid and electrolyte balance and eliminate metabolic waste. The affected individual might experience weakness, lethargy, shortness of breath, anemia, widespread edema (swelling), metabolic acidosis, rising potassium levels, heart arrhythmias, and more. These functions are vital to well-being and survival.
