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