PARA104 Lecture Notes - Lecture 5: Pulmonary Artery, Heart Valve, Purkinje Fibers
Document Summary
Carries oxygen from lungs to the tissues. Takes carbon dioxide from the tissues to the lungs. Behind the sternum and in front of the spine. Above the diaphragm and below the clavicles. The areas of the heart are important to know. Heart attacks (myocardial infarctions) are described by which area of the heart they affect. You will often hear these areas of the heart discussed during the analysis of 12 lead. The heart is housed in a fibrous sac called the. Fibrous pericardium, which surrounds and supports the heart. Some authors divide the myocardium into the subepicardial layer (superficial half) and the subendocardial layer (deep half): the endocardium (inside) houses the electrical system of the heart and extends to cover the valves. Coronary arteries in the myocardium (superficial to deep) Epicardial arteries (superficial to the heart) . The left and right coronary artery arise from the aorta. Roughly 4% of the population has a posterior.
