BSL Environmental Science Glossary - Coronary artery definition

Definition: The heart is encased in a layer of cells that need energy to pump the blood inside the heart circulating around the body. This energy comes from respiration. To do this, the blood needs O₂ (oxygen) and glucose. Blood is supplied to these cells by the coronary artery. The blood from inside the heart flows via a connection between the aorta and the coronary artery, allowing these cells to absorb the oxygen and glucose needed for the energy required to keep the heart pumping.
