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 respiratory system facilitates gas exchange between the atmosphere and the bloodstream, working closely with the cardiovascular system. Neural and chemical feedback loops regulate ventilation to maintain precise PaO2, PaCO2, and pH homeostasis.
