• Fenestrated elastic membranes are typical for the arteries of muscle type
• Continuous capillaries consist of an endothelial layer, its underlying basal lamina and associated pericytes within the basal lamina
• Pericytes are associated cells within the basal lamina of the endothelial cells of capillaries
• Adipose tissue is found in the epicardium
• In the region of fossa ovalis in septum interatriale there is no myocardium
• The atrioventricular node is situated in its subendocardial location
• The valves of the veins are double folding of tunica intima
• The right ventricle of the heart at cross section has semilunar shape
• There is adipose tissue in the heart epicardium
• The left ventricle of the heart at cross section has semilunar shape
• There is adipose tissue in the heart endocardium
• The lining of the inner walls of the heart's chambers is termed the visceral pericardium
• Subendothelium of blood vessels is loose connective tissue with blood vessels
• Tunica media of the aorta is made of fenestrated elastic membranes
• If the heart's natural pacemaker fails to fire, then the node on the floor of the right atrium would act as a secondary pacemaker
• Which tunic of an artery contains endothelium? Tunica intima
• The exchange of gases and nutrients between blood and tissues is a major function of capillaries
• Which of the following statements best describes arteries? All arteries carry blood away from the heart
• The circulatory pathway that carries blood from the digestive tract towards the liver is termed the hepatic portal circuit
• Immediately following strenuous and vigorous exercise, capillaries of the active muscles will be engorged with blood
• The lining of the inner walls of the heart's chambers is termed the endocardium
• The outermost layer of the heart's serous pericardium is termed the parietal pericardium
• The heart's natural pacemaker is termed the sinoatrial node
• What is most responsible for propelling blood in the arterial system during cardiac diastole? Elastic recoil of conducting (elastic) arteries
• The basal membrane of the fenestrated capillaries is continuous
• The layers of the endocardium are: Endothelial, Subendothelial, Myoelastic, Subendocardial
• The capillaries are: Continuous, Fenestrated, Discontinuous
• The valves between the atria and ventricles in the heart are: Bicuspidal or mitral, Tricuspidal
• The fibrous skeleton of the heart includes: Right fibrous ring, Left fibrous ring, Right fibrous trigone, Left fibrous trigone
• The arteries which supply the heart wall with blood are: Left coronary artery, Right coronary artery
• Typical for myocardium is: 3 types of muscle tissue cells - cardiac myocytes, Purkinje cells, Myocardial endocrine cells, Myocardium of the ventricles is organized in 2 layers
• The elements of the fenestrated capillaries are: Endothelial cells, Basal membrane - non-interrupted, Pericytes
