For which position maximum blood pressure in the body have the smallest value ?
Correct answer: D. Laying horizontally
- A. Standing straight
- B. Sitting on chair
- C. Sitting on ground
- D. Laying horizontally
Explanation
When a person lies horizontally, the vertical height difference between the head and feet is smallest, so the hydrostatic pressure difference ΔP = ρgh is also smallest. Students may choose standing because blood pressure is often discussed in that position, but standing creates the greatest height-related pressure variation.

About Fluid Flow
Fluid flow covers pressure, density, viscosity and the motion of liquids and gases through pipes or open channels. It includes the continuity equation, Bernoulli equation, streamline and turbulent flow, and the effects of changing area, height and speed. Viscosity and ideal fluid assumptions must not be confused with pressure effects.
