- Left ventricle
- corona =
- Right atrium
- superficial epicardium
- fibrous pericardium
1 of 4 chambers; smooth, thin, posterior wall; thin, rough anterior wall; receives superior and inferior venae cavae and coronary sinus
- b often infiltrated with fat (adipose), especially in older people. (visceral layer of the serous pericardium)
- c crown
- d ejects blood into the aorta (largest artery in the body)
- e tough, dense connective tissue layer protects the heart, anchors it to surrounding structures, and prevents overfilling of the heart with blood.
5 Multiple choice questions
- returns blood from body regions superior to the diaphragm. (lack oxygen)
- increase the atrial volume somewhat.
- left side of the heart. takes a long pathway through the entire body and encounters about five times as much friction or resistance to blood flow than the pulmonary circuit pump.
- the functional blood supply of the heart, is the shortest circulation in the body.
5 True/False questions
left coronary artery →
Passes between pulmonary trunk and right auricle; lies in the coronary sulcus; distributes blood to the right atrium, right ventricle and left ventricle.
fibrous skeleton of the heart → connective tissue fibers that form a dense network to reinforce the myocardium internally and anchor the cardiac muscle fibers.
Right ventricle → increase the atrial volume somewhat.
myocardium → middle layer of the heart wall; composed mainly of cardiac muscle and forms the bulk of the heart; circular and spiral arrangement of cardiac muscle.
Left ventricle →
1 of 4 chambers; thick muscular walls; separated from let atrium by left atrioventricular valve; walls twice as thick as right ventricle; forms apex; responsible for pumping oxygen-rich blood to body (except to lungs)
