Air Pressure Air is composed of molecules. Air is matter. It has mass and takes up space. Air is composed of different gases such as nitrogen‚ oxygen‚ carbon dioxide‚ water vapor‚ and other gases. Air molecules are in constant motion. As they move‚ they come in contact with surfaces. Air molecules push and press on the surfaces they contact. The amount of force per unit area that air molecules exert on a surface is called air pressure. (What is Air Pressure 6) Air pressure is caused by all

Atmospheric pressure is the force per unit area exerted on a surface by the weight of air above that surface 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 mass of air above the measurement point. Low-pressure areas have less atmospheric mass above their location‚ whereas high-pressure areas have more atmospheric mass above their location. Likewise‚ as elevation increases‚ there is

1.6 Blood Pressure Blood pressure is the main factor in sustaining blood flow through tissues. The force applied to the arterial walls as the heart pumps blood throughout the circulatory system defines the physiological meaning of blood pressure (Bojanov‚ 2009). Blood pressure is determined by the force‚ heartbeat rate‚ and resistance to blood flow through vessels. Cyclic changes in arterial blood pressure are partially attributed to the rhythmic contractions in the left ventricle (Iaizzo‚ 2009)
