Explanation: SA node pacemaker activity relies on the hyperpolarization-activated funny current (If) – mixed Na+/K+ inward current, plus decreasing outward K+ current.

Explanation: Hyperglycemia exceeds renal glucose reabsorption threshold → glucose in tubules → osmotic retention of water → increased urine output.

A) Increased parasympathetic (vagal) efferent activity to SA node B) Decreased sympathetic efferent activity to the heart C) Increased sympathetic efferent activity to the heart D) Increased atrial natriuretic peptide (ANP) secretion ganong physiology mcq pdf

Explanation: Hyperventilation → excessive CO2 exhalation → respiratory alkalosis (↓PaCO2, ↑pH).

Explanation: Hypotension reduces baroreceptor firing → increased sympathetic outflow to heart (β1 receptors) → increased HR. Vagal tone decreases, not increases.

A) Increased PaCO2, increased pH B) Decreased PaCO2, increased pH C) Decreased PaCO2, decreased pH D) Increased PaCO2, decreased pH This is a specific request, as "Ganong's Review

A) Decreased renin release B) Increased angiotensin II formation C) Decreased aldosterone secretion D) Increased ANP release
