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

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

A) Decreased renin release B) Increased angiotensin II formation C) Decreased aldosterone secretion D) Increased ANP release ganong physiology mcq pdf

A) Increased ADH secretion B) Decreased glomerular filtration rate C) Osmotic diuresis from glucosuria D) Inhibition of sodium reabsorption in the loop of Henle

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 Explanation: SA node pacemaker activity relies on the

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

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