Medical Terminology: Chapter 10 Blood pressure is the force that blood exerts against the vessel wall. During a normal cardiac cycle, blood pressure reaches a high point and a low point. The high point is referred to as systole and occurs when the ventricles of the heart contract, forcing blood into the aorta.

- Blood pressure (BP) is the pressure exerted by circulating blood upon the walls of blood vessels. When used without further specification, blood pressure usually refers to the arterial pressure in the systemic circulation. It is usually measured at a person's upper arm. Blood pressure is usually expressed in terms of the systolic (maximum) pressure over diastolic (minimum) pressure and is measured in millimeters of mercury (mm Hg). It is one of the vital signs along with respiratory rate, heart rate, oxygen saturation, and body temperature.

Capillary Exchange Blood hydrostatic pressure is the force exerted by the blood confined within blood vessels or heart chambers. Even more specifically, the pressure exerted by blood against the wall of a capillary is called capillary hydrostatic pressure (CHP), and is the same as capillary blood pressure. CHP is the force that drives fluid out of capillaries and into the tissues.

What causes 'the bends'? SCUBA diving is different from holding your breath and diving, and to understand the difference you need to understand the incredible pressures that a diver's body experiences. When we are living on dry land at sea level, the air around us has a pressure of 14.7 PSI (pounds per square inch), or 1 atmosphere.

Pressure Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled gage pressure)[a] is the pressure relative to the ambient pressure.

A pound per square inch is equal to about 6,890 pascal.

Energy, Plants & Man Crushing pressure. Human bodies are used to air pressure. The air pressure in our lungs, ears and stomachs is the same as the air pressure outside of our bodies, which ensures that we don’t get crushed. Our bodies are also flexible enough to cope when the internal and external pressures aren’t exactly the same.

- HOW DOES AIR PRESSURE AFFECT THE BODY? Air pressure is the force that is exerted on you by air molecules, being the weight of tiny air particles. Atmospheric pressure is a measure of the force exerted by the atmosphere, so therefore at any point on the earth’s surface, there is a quantity of air sitting above your body.

Pressure Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled gage pressure) is the pressure relative to the local atmospheric or ambient pressure. Various units are used to express pressure.

PRESSURE EFFECTS ON HUMAN PHYSIOLOGY The weight of the earth’s atmosphere of oxygen and nitrogen exerts a pressure-applied force, or barometric pressure, against the exposed surface of the pool of mercury with sufficient force to raise a column of mercury inside the sealed glass tube up to a height of 760 mm above the surface of the pool of mercury.

Pressure points Home Articles Human Body & Health. Pressure points. Pressure points are vital points or weak points of the body where a blood vessel or (in most cases) a nerve is very close to the skin. Pressure on these points can cause pain, injury or even death if an atemi (blow) is applied.

How much force can a human body withstand? Human tolerances depend on the magnitude of the g-force, the length of time it is applied, the direction it acts, the location of application, and the posture of the body. The human body is flexible and deformable, particularly the softer tissues.   As far as sustained pressure the human body can withstand as much as 4 … 00 PSI providing it is gradually increased to this amount.

Q&As on hypertension The higher the pressure, the harder the heart has to pump. Normal adult blood pressure is defined as a blood pressure of 120 mm Hg1 when the heart beats (systolic) and a blood pressure of 80 mm Hg when the heart relaxes (diastolic).

Vital Signs (Body Temperature, Pulse Rate, Respiration Rate, Blood Pressure) A Carolinas HealthCare System answered. Blood pressure is the pressure of the blood against the walls of the arteries. Blood pressure results from two forces. One is created by the heart as it pumps blood into the arteries and through the circulatory system. The other is the pressure in the arteries as the heart relaxes. Blood pressure changes during the day.

Human Physiology/Homeostasis Blood pressure is expressed as two different numbers. The first number is called the systolic blood pressure, and the second is the diastolic blood pressure. Systolic blood pressure is the pressure at the time of the cardiac cycle when the heart contracts, forcing blood out(called systole). This is the time of greatest pressure.

Pressure points in the human body? There are hundreds of pressure points in the human body, accessing them however is not so easy. Some of the pressure points are close to the surface like your 'funny bone' while others are deeper and often partially covered.

- Even though they’re too tiny to see, all the molecules of air in the atmosphere above your head weigh something. And the combined weight of these molecules causes a pressure pressing down on your body of 10,000 kg per square metre. This means that the mass of the air above the 0.1 square metre cross section of your body is 1,000 kg, or a tonne.

Blood pressure and your brain Blood pressure is the vital force that propels oxygen-rich blood to all parts of your body. Your heart is the pump that generates the force, and your arteries are the channels that transport and distribute the blood. The height of your blood pressure is determined by how forcefully your heart's main pumping chamber, the left ventricle, contracts, and by the diameter and stiffness of your arteries.

Atmospheric pressure Atmospheric pressure is the pressure exerted by the weight of air in the atmosphere of Earth (or that of another planet). In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point.he standard atmosphere (symbol: atm) is a unit of pressure equal to 101325 Pa or 1013.25 hectopascals or millibars. Equivalent to 760 mmHg (torr), 29.92 inHg, 14.696 psi.

Atmospheric Pressure The atmospheric pressure at the surface of the Earth is about 14.7 psi. That means that the weight of a column of air which has a cross section of 1 square inch and which stretches from the surface of the Earth to space is 14.7 pounds (on the average). Atmospheric pressure is measured with a barometer.he temperature at the surface is hot enough to melt lead, and the atmospheric pressure at the surface is 90 times that at the surface of the Earth!!! Because the atmosphere is so dense and so cloudy, it is not possible to see the surface of Venus from outside its atmosphere.
