The class iv calcium blocker that exclusively administered to treat acute supraventricular tachyxardia is Diltiazem. Calcium channel blockers obstruct the movement of calcium into conductive and contractile myocardial cells by inhibiting the influx of calcium through its channels, causing a slower conduction through the SA and AV. Diltiazem is administered intravenously to treat acute supraventricular tachycardia.

External respiration (correct answer) involves the exchange of oxygen and carbon dioxide within the environment.
The exchange of wastes through the skin is just called excretion by sweating.
There is no exchange of nutrients that occur in the lungs but rather absorption of nutrients is the function of the gastrointestinal tract.
The exchange of oxygen and carbon dioxide within the cell is called cellular respiration and involves carrying oxygen from the blood to the cell then the cell uses it as the final electron acceptor in the electron transport chain. The metabolic wastes of the cell, primarily carbon dioxide, goes now to the bloodstream to be exchanged for oxygen in the lungs.
