Cell Signalling and Transduction Nitroglycerin has long been administered to human patients suffering from chronic chest pain (angina). This medication works because it mimics the action of signal receptors is broken down into hormones that affect the heart breaks down into nitric oxide, which increases blood flow to the heart interferes with chemical cascades that trigger contraction of heart muscle mimics the action of signal receptors is broken down into hormones that affect the heart breaks down into nitric oxide, which increases blood flow to the heart interferes with chemical cascades that trigger contraction of heart muscle ANSWER DOWNLOAD EXAMIANS APP
