1

Arteries carry __________ blood at __________ pressure.

65% Answer Correctly

oxygenated, high

deoxygenated, high

oxygenated, low

deoxygenated, low


Solution

Veins carry blood back to the heart from the body. While arteries are thick-walled because they carry oxygenated blood at high pressure, veins are comparatively thin-walled as they carry low-pressure deoxygenated blood. Like the heart, veins contain valves to prevent blood backflow.


2

Which of the following is not a base unit in the metric system?

88% Answer Correctly

liter

meter

gram

degree Fahrenheit


Solution

The Fahrenheit scale is used for measuring temperature in the British system. The metric system uses the Celsius scale.


3

Veins carry blood __________ the heart.

55% Answer Correctly

back to 

away from

all of these

within


Solution

Veins carry blood back to the heart from the body. While arteries are thick-walled because they carry oxygenated blood at high pressure, veins are comparatively thin-walled as they carry low-pressure deoxygenated blood. Like the heart, veins contain valves to prevent blood backflow.


4

Work is measured in:

75% Answer Correctly

horsepower

joules or newton-meters

watts

amps


Solution

Work is performed on an object when an applied force causes displacement along the same vector. Measured in joules (J) or newton-meters (Nm), work is calculated by multiplying force times displacement:  \(W = \vec{F}\vec{d}\)


5

Which of the following represents the largest value?

61% Answer Correctly

1 ML

1 mL

1 cL

1 kL


Solution

Mega (M) is 106, kilo (k) is 103, centi (c) is 10-2, milli (m) is 10-3 so 1 ML represents the largest value.
