- 2 layers of te pericardium
- interventricular septum
- also called the epicardium
- a around
- b the internal partition that divides the heart longitudinally at the ventricles.
- c parietal: lines the internal surface of the fibrous pericardium. attaches to the large arteries exiting the heart then turns inferiorly and continues over the external heart surface as the visceral layer.
- d visceral layer of the serous pericardium
- e pumps blood into the pulmonary truck, which routes the blood to the lungs where gas exchange occurs.
5 Multiple choice questions
- conelike, play a role in valve function, project into the ventricular cavity.
- irregular ridges of muscle that line the internal walls of the ventricular chambers.
- returns blood from body regions superior to the diaphragm. (lack oxygen)
Origin: Right ventricle; Distributes to the lungs; pumps oxygen-poor blood from right ventricle; has the pulmonary valve at its origin.
- increase the atrial volume somewhat.
5 True/False questions
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)
Right ventricle →
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.
coronary circulation → the functional blood supply of the heart, is the shortest circulation in the body.
Function of Ventricles → Collect blood returning to the heart.
