- fibrous pericardium
- Function of Ventricles
- serous pericardium
- interatrial septum
- left coronary artery
- a deep to the fibrous pericardium: a thin, slippery, 2-layer serous membrane. its parietal layer lines the internal surface of the fibrous pericardium.
- b tough, dense connective tissue layer protects the heart, anchors it to surrounding structures, and prevents overfilling of the heart with blood.
- c to pump blood from the heart.
- d runs toward the left side of the heart and then divides into its major branches.
- e the internal partition that divides the heart longitudinally at the atria
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)
- often infiltrated with fat (adipose), especially in older people. (visceral layer of the serous pericardium)
- 4 veins: enter the left atrium; transport blood from the lungs back to the heart (best seen posteriorly)
5 True/False questions
Purkinje fibers → the double walled sac surrounding the heart.
Pulmonary Trunk →
Origin: Right ventricle; Distributes to the lungs; pumps oxygen-poor blood from right ventricle; has the pulmonary valve at its origin.
Ascending aorta →
Ascends short distance within the pericardium; Has aortic valve at its origin; origin: Left ventricle (aortic vestibule)
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.
inferior vena cava → returns blood from body regions superior to the diaphragm. (lack oxygen)
