Calcium channel blockers inhibit the movement of calcium ions from the interstitial fluid into cardiac and smooth muscle cells. This would cause a decrease in heart rate, stroke volume, and cardiac output. These in turn would lower blood pressure. In addition, the calcium channel blockers would also inhibit contraction of the smooth muscle in the wall of blood vessels, causing them to get wider and thus also lower blood pressure. Because both heart and smooth muscle cells are inhibited by verapamil, its effects on blood pressure are particularly potent.

Answer:
Birds have a significant number of reduced muscles to help them reduce their weight. The most-developed muscles in birds are the flight muscles that they need to fly. The bones are mostly fused, reducing the need for muscles to hold the bones together. The skulls of birds are very thin and the beaks are very light.
