To determine: The difference in resistance to blood flow in a blood vessel of radius 60μm and a capillary of radius 4μm.
Introduction: The blood vessel represents one of the major components of the human circulatory system is responsible for the circulation of blood. The blood vessels are of different types such as arteries (carries blood away from the heart), veins (carries blood to the heart from the body and tissues), and more.
Explanation of Solution
The size of blood vessels varies in each one of them. The aorta has the largest radius, while the capillaries are known to have the lowest radius. The narrower the blood vessel, the greater the frictional resistance to blood flow. The radius of a blood vessel is 60μm while of a capillary is 4 μm hence the difference is 15 fold (60/4) and because the resistance increases to the fourth power in inverse proportion while the difference in resistance to blood flow will be 15 to the fourth power or 154 which is equal to 50,625.
