Hace 3 días · Blood pressure (BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured.
13 de may. de 2024 · pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. The pressure exerted on a floor by a 42-pound box the bottom of which has an area of 84 square inches is equal to the force divided by the area over which it is exerted; i.e., it is one-half pound per square inch.

Hace 5 días · Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. High blood pressure usually does not cause symptoms itself.
Hace 2 días · The compressibility of water is a function of pressure and temperature. At 0 °C, at the limit of zero pressure, the compressibility is 5.1 × 10−10 Pa−1. At the zero-pressure limit, the compressibility reaches a minimum of 4.4 × 10−10 Pa−1 around 45 °C before increasing again with increasing temperature.
25 de may. de 2024 · The systolic pressure (the higher pressure and the first number recorded) is the force that blood exerts on the artery walls as the heart contracts to pump the blood to the peripheral organs and tissues.
20 de may. de 2024 · High blood pressure is also known as hypertension. It happens when the force of your blood pushing against the walls of your blood vessels is too high. High blood pressure can lead to other serious problems such as heart attack and stroke. Watch video: Is there a difference between hypertension and high blood pressure?
