Fenestrated elastic membranes are typical for the arteries of muscle type.
Yes
No
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 has a semilunar shape
There is adipose tissue in the heart endocardium
The lining of the inner walls of the hearts chambers is termed visceral pericardium
yes
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 hearts 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

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

coronary circuit
cerebral circuit
hepatic portal circuit
pulmonary circuit
Immediately following strenuous and vigorous exercise which of the following is mot likely to occur?
blood will be rapidly diverted to the digestive orangs
the skin will be cold and clammy
capillaries of the active muscles will be engorged with blood

skeletal muscle contraction and breathing
hydrostatic blood pressure arising from ventricular contraction
elastic recoil of conducting elastic arteries
venous return of blood
