Fenetstrated 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 with 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 semi-lunar 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 without blood vessels
Loose connective tissue with blood vessels
Loose connective tissue with glands
Muscle tissue
Tunica media of the aorta is made of:
Elastic and muscle tissue
Fenestrated elastic membranes
If the heart's natural pacemaker fails to fire, then:
No blood would enter the atria
No blood would enter the ventricles
The node on the floor of the right atrium would act as a secondary pacemaker
The node on the floor of the left ventricle would act as a secondary pacemaker
The person would die within minutes
Which tunic of an artery contains endothelium?
Tunica interna/intima
Tunica media
Tunica externa
The exchange of gases and nutrients between blood and tissues is a major function of:
Arterioles
Arteries
Capillaries
Veins
Which of the following statements best describe arteries?
All arteries carry oxygenated blood towards the heart
All arteries contain valves to prevent the back-flow of blood
All arteries carry blood away from the heart
Only large arteries are lined with endothelium
The circulatory pathway that carries blood from the digestive tract towards the liver is termed the:
Coronary circuit
Cerebral Circuit
Hepatic Portal Circuit
Pulmonary circuit
Immediately following strenuous and vigorous exercise, which of the following is most likely to occur?
Blood will be rapidly diverted to the digestive organs
The skin will be cold and clammy
Capillaries of the active muscles will be engorged with blood
Blood flow to the kidneys quickly increases
The lining of the inner walls of the heart's chambers is termed the:
Visceral pericardium
Serous pericardium
Epicardium
Myocardium
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
Atrioventicular node
Bundle of His/Atrioventicular Bundle
Left and Right bundle branches
Purkinje fibers
What is most responsible for propelling blood in the arterial system during cardiac diastole?
Skeletal muscle contraction and breathing
Hydrostatic blood pressure arising from ventricular contraction
Elastic recoil of conducting (elastic) arteries
Venous return of blood
Typical for myocardium is:
3 types of muscle tissue cells; Cardiac myocytes, Purkinje cells, myocardial endocrine cells
Myocardium of the ventricle is organised in 2 layers
Myocardium of the ventricles is organised in 3 layers
The elements of the fenestrated capillaries are:
Endothelial cells
Basal membrane - Interrupted
Basal membrane - Non-interrupted
Pericytes
