The coronary arteries branch off from the aorta, which is the largest artery in the body. These arteries encircle the heart and branch out into smaller vessels that penetrate the heartmuscle, providing it with a rich blood supply.
When the heartmuscle contracts during each heartbeat, it requires a significant amount of energy in the form of oxygen and nutrients. The coronary arteries deliver oxygenated blood to the heart, ensuring that it can continue to pump effectively.
Coronary Artery Disease (CAD): This condition occurs when the coronary arteries become narrowed or blocked due to the buildup of plaque, leading to reduced blood flow to the heart.
Coronary Artery Spasm: In this condition, the coronary arteries undergo sudden, brief contractions, leading to a temporary reduction in blood flow to the heart.
Coronary Artery Dissection: This is a rare but serious condition where a tear forms in the coronary artery wall, leading to abnormal blood flow and potential complications.
Study Guide
To effectively study coronary arteries, it is important to understand their structure, function, and common disorders. Key areas to focus on include:
Identifying the main branches of the coronary arteries and their specific roles in supplying blood to different regions of the heart.
Understanding the risk factors, symptoms, and potential complications associated with coronary artery disease and other disorders.
Learning about diagnostic tests, such as angiography and cardiac CT scans, used to assess the health and function of the coronary arteries.
Exploring treatment options for coronary artery disease, including lifestyle modifications, medications, and surgical interventions such as angioplasty and bypass surgery.

Energy - A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc 2 . B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion. C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy. D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields. E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.
