1. Some people with heart conditions place a nitroglycerin tablet under the tongue when feeling chest pain (angina pectoris). Nitroglycerin acts on the smooth muscle surrounding blood vessels, causing relaxation and vessel dilation. How does this work to help with the symptoms of chest pain? 2. Mr. Thompson is a 50 year-old male who went to the hospital after he felt like he was having a heart attack while playing some basketball with his son. Further tests showed that while Mr. Thompson only had a particularly painful bout of angina pectoris, there was still an 80% blockage of his right coronary artery. Describe what occurred in Mr. Thompson's case in terms of myocardial oxygen supply and demand when his sympathetic nervous system was stimulated during the basketball playing.
