A Correct answer
Explanation

Blood pressure is the force exerted by circulating blood against the walls of blood vessels, primarily arteries. It's measured in mmHg and expressed as systolic/diastolic pressures. Option B is wrong (not just legs), C is wrong (not from atrium), D is wrong (ventricles generate pressure, but blood pressure is defined against vessel walls throughout circulation).
