The average fluid pressure in the aorta of 100 mm Hg = 13332.2 Pa (this is the pressure relative to the outside of the vessel). Supposing that the blood flows continuously throughout the body, what is the total energy (the sum of the kinetic energy and the energy due to the fluid pressure) of the blood per unit volume of blood in the aorta when the body is at rest and during activity?
The speed of blood at rest is 0.17m/s.
The speed of blood during physical activity is 0.85m/s.

The blood pressure at your heart is approximately 100 mm of Hg. As blood is pumped from the left ventricle of your heart, it flows through the aorta, a single large blood vessel with a diameter of about 2.5 cm. The speed of blood flow in the aorta is about 60 cm/s. Any change in pressure as blood flows in the aorta is due to the change in height: the vessel is large enough that viscous drag is not a...

The aorta is approximately 25 mm in diameter. The mean pressure there is about 100 mmHg, and the blood flows through the aorta at approximately 60 cm/s. Suppose that at a certain point a portion of the aorta is blocked so that the cross‑sectional area is reduced to 1/3 of its original area. The density of blood is 1060 kg/m3. (a) How fast v ( in cm/s) is the blood moving just as it enters the blocked portion of the...

In the normal region of an artery, the blood pressure is 100 mm Hg and the flow speed is 0.12m/s. By what percentage would the pressure drop in this artery as the blood (density 1.05 x 10^3 kg/m^3) enters a region that has been narrowed by atherosclerotic plaque to a cross-sectional area one fifth of normal? Assume there is no change in elevation of artery and viscosity is negligible

na obnerence yorm Flease sShow work & state assumptions. In the human lymphatic system, the spleen works to filter out old or damaged red blood cells and to create white blood cells (leukocytes). The spleen allows healthy red blood cells (erythrocytes) to pass through and uses lymphocytes, a type of white blood cell, to break down unhealthy erythrocytes into components that can be saved and reused to make new red blood cells.
