Describe how the heart as a muscle does its job of pumping blood. what happens if the cardiac muscle itself doesnt get enough blood

The aortic valve is in the left ventricle. When the heart muscle contracts (or beats), it is pumping blood out of the heart. ... The right side collects oxygen-poor blood from the body then pumps it to the lungs where it can pick up oxygen and release carbon dioxide.

pretty sure you will go in cardiac arrest and have to be hospitalized

you should wear a lead protective shield when having teeth x-rays
