The differences in size has to do with the function of the vessels; where they came from and where they are going.
Fluid pressure is the greatest at the deepest point. If the fluid is in different shaped vessels, the pressure is the greatest at the bottom of the vessel no matter what the shape.
That depends on the kind of vessel you are talking about. Blood vessels, for instance, carry blood. Sailing vessels, on the other hand, carry crew, passengers, and cargo.
the operators of both vessels
vasoconstriction is when your blood vessels contract.
The purpose of heat tape is to maintain and control pipes and vessels. This also keeps the heat that is being radiated from the pipes and vessels inside.
compare the kinds of blood vessels according to the thickness of the walls
Capillary
The smallest blood vessels are the capillaries.
Closed circulatory systems have the blood closed at all times within vessels of different size and wall thickness. In this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities.
Thickness of the walls.
capillaries
technically nominal wall thickness refers to pipe wall thickness (average)..if you are referring to shell/hull/fore part of a vessel, the thickness varies depending of type, size, deadweight of the vessel
Capillaries are the smallest blood vessels in the body (in terms of diameter), measuring about 20 micrometres (or one cell) across.
Because of their functions. Arteries have a very thick middle and outer layers because they have to bear the high pressure of blood coming from the heart. The walls of veins are thin because they carry blood at low pressure (but they have valves), and capillaries are only one cell thick because they have to exchange nutrients and wastes with the interstitial fluid.
3 different types of blood vessels are the arteries veins and capillaries
Vasodilation is relaxation of blood vessels leading to increase in lumen size. Vasoconstriction is contraction of blood vessels leading to decrease in lumen size.
Which vessels carry deoxygenated blood from different parts of the body to the heart
