1 of 4 chambers; rough, muscular walls; muscle wall thicker than either atrium and thinner than left ventricle; Responsible for pumping oxygen poor blood to lungs.
- b visceral layer of the serous pericardium
- c supplies the left atrium and the posterior walls of the left ventricle.

5 Multiple choice questions
- -The endocardium is the inner layer of the heart. It consists of epithelial tissue and connective tissue.
-Lines the inner cavities of the heart, covers heart valves and is continuous with the inner lining of blood vessels. (the inner lining of vessels are endothelial cells)
-Purkinje fibers are located in the endocardium. They participate in the contraction of the heart muscle.
- the double walled sac surrounding the heart.
- 4 veins: enter the left atrium; transport blood from the lungs back to the heart (best seen posteriorly)
- also known clinically as the left anterior descending artery: follows the anterior interventricular sulcus and supplies blood to the interventricular septum and anterior walls of both ventricles;
5 True/False questions
peri = → heart
Right ventricle → pumps blood into the pulmonary truck, which routes the blood to the lungs where gas exchange occurs.
Right 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.
superficial epicardium → often infiltrated with fat (adipose), especially in older people. (visceral layer of the serous pericardium)
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.
