Fenestrated elastic membranes are typical for the arteries of muscle type
Yes
No
Continous 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 iteratriale 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
The lining of the heart epicardium is mesothelium
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
The heart's natural pacemaker is termed the:
atrioventricular node
bundle of His/atrioventricular bundle
sinoatrial node
left and right bundle branches
Which tunic of an artery contains endothelium
Tunica interna (intima)
tunica media
tunica externa
The exchange of gases and nutrients between blood and tissue is a major function of:
arterioles
arteries
capillaries
veins
Which of the following statements best describes 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
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 situated in:
right atrium
near the atrioventricular node
near the bundle of His (atrioventricular bundle)
possess left and right bundle branches
left chamber
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
