Final answer:
The statement is false; a reading of 120/80 represents blood pressure, not velocity. This measurement indicates the systolic and diastolic pressures in the body.
Step-by-step explanation:
A false statement is that a reading of 120/80 indicates blood velocity. Instead, this reading represents blood pressure, with the numbers reflecting systolic and diastolic pressures. Systolic pressure occurs during ventricular contraction when the heart pushes blood out, and diastolic pressure is measured when the heart relaxes. Systemic blood pressure must stay above certain levels to ensure proper body function, including filtration.
The value of 120/80 mm Hg can be converted into newtons per square meter using the formula P = hpg, where h is the height pressure head, p is the density of the fluid, and g is the acceleration due to gravity.
This conversion is useful for understanding pressure in different units.
