What is normal blood pressure (B.P.)?
Blood pressure means the lateral pressure of the circulating blood on the vessel wall of the arterial blood channels. The blood pressure essentially depends on two factors—
Blood pressure means the lateral pressure of the circulating blood on the vessel wall of the arterial blood channels. The blood pressure essentially depends on two factors—
The pressure of flow of blood in the aorta and its main branches is defined as blood pressure. The heart has to develop a high pressure so that blood can be pumped through the fine capillaries. This blood pressure varies from one part of body to another.
The main effects of pressure on the boiling point of liquids are: - All liquids expand when they vaporize. The effect of pressure on the surface the expansion and delay vaporization. Thus, the boiling point is raised on the application of pressure
When pressure is applied on the surface of a normal solid, expansion is suppressed and melting is delay. Thus, the melting point of a normal solid is raised.
