Blood pressure
Blood flows away from the heart and is measured as blood pressure. This is a measure of the passage or flow and the resistance of the flow in the arteries.
Blood pressure
Maintaining blood pressure.
Arteries are blood vessels taking the blood away from the heart. the heart is a very powerful muscle so blood is ejected out at a high velocity and with high pressure.
No, its higher in the arteries due to the pressure of the heart beating.
Blood flow is faster in arteries than in veins. Blood flow in veins is lower pressure.
Blood pressure refers to the blood flow and resistance in the arteries. The device used to measure blood pressure is the sphygmomanometer or sphygmometer.
A pressure gradient exists in the arteries because the heart actively pumps the blood; additionally, the elasticity of the larger arteries helps force the blood along. There is a lower pressure gradient within the veins that is generated by the muscles squeezing the blood along back to the heart (assisted by valves within the veins).
