    Coronary Heart Disease (CHD) is a disease in which waxy substance called plaque builds up inside the coronary arteries. These arteries are used to supply oxygen-rich blood to your heart‚ so if they’re continuously blocked up‚ it can be very dangerous. If the flow of this oxygen-rich blood is reduced or blocked‚ a heart attack can occur.

    coronary sinus. The blood then passes through the tricuspid valve into the right ventricle. With each contraction‚ the right ventricle pumps blood through the pulmonic valve into the pulmonary artery and to the lungs. Blood flows from the lungs to the left atium by way of the pulmonary veins. It then passes through the mitral valve and into the left ventricle. As the heart contracts‚ blood is ejected through the aortic valve into the aorta and thus enters the high-pressure systemic
