Question

we do not feel the enormous pressure extracted by the atmosphere on us because pressure of the blood is in the blood vessels______​

Answer 1

Answer:

Pressure is a measure of the force that the blood exerts against the vessel walls as it moves the blood through the vessels. Like all fluids, blood flows from a high pressure area to a region with lower pressure. Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins.Important: The highest pressure of circulating blood is found in arteries, and gradu- ally drops as the blood flows through the arterioles, capillaries, venules, and veins (where it is the lowest). The greatest drop in blood pressure occurs at the transition from arteries to arterioles.Increased pressure in the veins does not decrease flow as it does in arteries, but actually increases flow. Since pressure in the veins is normally relatively low, for blood to flow back into the heart, the pressure in the atria during atrial diastole must be even lower.
