- right auricle
- cardi =
- ventr =
- Left ventricle
- a heart
- b "inside the heart" is a glistening white sheet of endothelium (squamous epithelium) resting on a thin connective tissue layer. Located on the inner myocardial surface, it lines the heart chambers and covers the fibrous skeleton of the valves.
- c underside
- d ejects blood into the aorta (largest artery in the body)
- e increase the atrial volume somewhat.
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 functional blood supply of the heart, is the shortest circulation in the body.
- visceral layer of the serous pericardium
- Purkinje fibers (Purkyne tissue or Subendocardial branches) are located in the inner ventricular walls of the heart, just beneath the endocardium. These fibers are specialized myocardial fibers that conduct an electrical stimulus or impulse that enables the heart to contract in a coordinated fashion.
1 of 4 chambers; smooth, thin, posterior wall; thin, rough anterior wall; receives superior and inferior venae cavae and coronary sinus
5 True/False questions
fibrous pericardium → deep to the fibrous pericardium: a thin, slippery, 2-layer serous membrane. its parietal layer lines the internal surface of the fibrous pericardium.
Coronary sulcus →
Surface groove surrounding heart; marks junction between atria and ventricles
pectinate muscles → bundles of muscle that look like the teeth of a comb inside of the anterior portion of the right atrium.
Superior vena cava → returns blood from body regions inferior to the diaphragm. (lack oxygen.
papillary muscles → conelike, play a role in valve function, project into the ventricular cavity.
