- Anterior interventricular sulcus
- Where is the endocardium found and what kind of tissue is it?
- coronary sinus
- also called the epicardium
- a visceral layer of the serous pericardium
- b collects blood draining from the myocardium
- c -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.
Groove on anterior surface; extends from coronary sulcus to inferior margin; marks position of interventricular septum;
- e the double walled sac surrounding the heart.
5 Multiple choice questions
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)
- the internal partition that divides the heart longitudinally at the ventricles.
1 of 4 chambers; smooth, thin, posterior wall; thin, rough anterior wall; receives superior and inferior venae cavae and coronary sinus
- supplies the left atrium and the posterior walls of the left ventricle.
- tough, dense connective tissue layer protects the heart, anchors it to surrounding structures, and prevents overfilling of the heart with blood.
5 True/False questions
fibrous skeleton of the heart → connective tissue fibers that form a dense network to reinforce the myocardium internally and anchor the cardiac muscle fibers.
pulmonary veins →
Origin: Right ventricle; Distributes to the lungs; pumps oxygen-poor blood from right ventricle; has the pulmonary valve at its origin.
Purkinje fibers → 4 veins: enter the left atrium; transport blood from the lungs back to the heart (best seen posteriorly)
superior vena cava → returns blood from body regions inferior to the diaphragm. (lack oxygen.
cardi = → heart
