(CH. 20-22)
The walls of arteries and veins are composed of: - ANS Collagenous fibers & Elastic fibers
The pressure withstand by veins are much lower than arteries of the blood that flows from them -
ANS TRUE
Pick the incorrect statement for tunica intima: - ANS Internal elastic membrane present in large
vessels
Vasoconstriction decreases blood flow as: - ANS Smooth muscle in the wall of tunica media contracts
Artery conducts blood in direction: - ANS Away from the heart
The diameter of muscular artery typically ranges from: - ANS 0.1-10mm
A channel that supplies blood to tissues: - ANS Capillary
Which of the following can't pass between the cells - ANS RBCs
The capillary having pores in addition to tight junctions in the endothelial lining - ANS Fenestrated
capillary
The factors affecting vasomotion does not include: - ANS Carbon ion
Venules as well as capillaries are the primary sites of emigration or diapedesis, in which the ------------
------ adhere to the endothelial lining of the vessels and then squeeze through adjacent cells to enter
the
tissue fluid. - ANS White blood cells
Pick the correct statement:
, (A) Arteries are thick as compared to veins
(B) Pressure in arteries is low
(C) Arteries are irregular
(D) Veins are rounded - ANS A
The blood volume of systemic veins at any time: - ANS 64%
The force exerted by blood upon the walls of the blood vessels or chambers of the heart: - ANS Blood
pressure
Pulse pressure is: - ANS Difference between systolic and diastolic pressure
Pulse can be found in:
A) Temporal arteries
(B) Facial arteries
(C) Brachial arteries
(D) All of them - ANS D
Which one of the following is an incorrect step of procedure for measuring blood pressure? - ANS
The clinician squeezes a rubber pump to take out air into the cuff, decreasing pressure
around the artery and temporarily cutting off blood flow into the patient's arm
TRUE or FALSE: Blood moves from higher pressure to lower pressure. - ANS TRUE
Cardiac output is measured in: - ANS Liters per minute
In Poiseuille's equation π is: - ANS Mathematical constant
