Definitions for "Blood pressure"
Tension of blood in arteries. Hypertension means that pressure is raised.
The amount of pressure blood exerts against the walls of the arteries. The upper number refers to the systolic pressure (the amount of pressure when the heart contracts), and the lower number refers to the diastolic pressure (the amount of pressure when the heart relaxes). During pregnancy, blood pressure drops toward the second trimester and then rises again in the third trimester. High blood pressure during pregnancy can be caused by preeclampsia.
The pressure exerted by the blood on the wall of the arteries. Maximum and minimum measures are used: 'Me systolic pressure reaches a maximum just before the end of the pumping phase of the heart; the diastolic pressure minimum occurs late in the refilling phase of the heart. Measures are in millimeters of mercury (as 120/80). See hvertenson.
