    central venous pressure

    Explanation:

    Two venae cavae return the deoxygenated blood from the rest of the body to the heart. The blood is returned to the right atrium. The two venae cavae performing this function are, superior vena cava and inferior vena cava. The blood pressure in these venae cavae is called central venous pressure. It is affected by various factors like exhalation, inhalation, pulmonary hypertension, heart failure etc.

    Option B, Central venous pressure

    Explanation:

    Central venous pressure (CVP) is the mean pressure in the vena cava or near the right atrium of heart. CVP is generally expressed in millimeters of mercury i. e mm Hg.

    CVP in general is determined by the balance between the output of right ventricles and return from systemic venous thereby making it the pressure arising from largest systemic veins. It represents the pre-load index of left ventricle

    Hence, Option B is correct
