Question 16 Considere O mean aterial prus e blood preaaure reading of 120v80.120 comesponds to the o Blood osmote pssue. O pube pressu Question 17 If blood has low viscosity, which resuit wouldt be lkoly under normal condtions Blood fows against high resistance O Bliood contains increased sumbers of plasme proeins and suspended blood cels OBlood fow cannot oocur Blood tows at higher preseres O Blood Nows at lower pressures Question 18 As blood travels from the aorta toward the capiliaries, O cardovascular pressure decreases vascular flow increases O both cardiovascular pressure and vascular fow increase Ovascular resistance decreases O viscosity decreasesExplanation / Answer
16. Last option is the correct answer. 120 indicates blood pressure during systolic contraction and 80 indicates pressure during diastolic pressure. During systolic contraction, blood pumps out of the heart and thus blood pressure is higher while during diastole, the heart fills with impure blood and thus pressure is lower.
17. Last option is the correct answer. A viscous fluid require more pressure to flow while less viscous fluid require less pressure to flow. Thus, if blood has low viscosity, the blood will flow at low pressure.
18. Option first is the correct answer. The pressure at the begining of aorta is high and it decreases as it moves towards capillaries because blood from the aorta are goes into multiple branches from aorta and thus, cardiovascular pressure decreases.
