(a) Calculate the difference in blood pressure between the feet and top of the head for a person who is 1.65 m tall. (b) Consider a cylindrical segment of a blood vessel 2.00 cm long and 1.50 mm in diameter. What additional outward force would such a vessel need to withstand in the person’s feet compared to a similar vessel in her head?

When measuring blood pressure, why is the cuff placed at the level of the heart? Would the blood pressure reading change if it were taken at the proximal thigh? Why? Your answer should include a discussion on what factors determine the pressure of a fluid.
Smoking can cause a person's arteries to constrict to 90 % of their normal radius. If the usual pressure difference needed to maintain a healthy blood flow rate in an artery is 405 Pa, what new pressure difference is needed to maintain the same volume flow rate (NOT flow speed)? You may assume that the artery has a length of 10 cm, a radius of 2 mm, and that blood has a viscosity of 2.7×10−3N⋅s/m2.7×10−3N⋅s/m. (in Pa) 450 328 617 500 266
10) Water circulates throughout an apartment complex in a hot water heating system. (a) If the water is pumped at a speed of 0.50 m/s through a 4.0 cm diameter pipe under a pressure of 3.1 × 105 Pa, what will be the velocity and pressure in a 2.6 cm diameter pipe on the second floor 5.0 m above? (b)If the apartment building is 8 floors total, will there be enough pressure for the water to get to the top floor? Explain your reasoning. (You can assume every floor is 5m and that the pipe size stays 2.6 cm)
Atherosclerosis is a cardiovascular disease that involves the accumulation of cholesterol in the arterial wall in regions with damaged endothelial cells. Assume that the damaged region is a circular hole with radius b. the thickness of the endothelial layer can be neglected. The endothelial layer is impermeable to cholesterol and plasma, except in the damaged region. The subendothelial space can be treated as a semi-infinite porous material with hydraulic conductivity K. The transport of fluid and cholesterol is in the radial direction and is symmetric about the center of the hole. The diffusion coefficient of cholesterol in the subendothelial tissue is D. The concentration of cholesterol and the hydrostatic pressure at r = b are approximately equal to those in the plasma, which are Cp and p0 respectively. The concentration and pressure at r→∞ are assumed to be zero. Determine the distribution of pressure in the subendothelial space in the steady state and evaluate the pressure at r =…

Under normal circumstances, the vitreous humor, a jelly-like substance in the main part of the eye, exerts a pressure of up to 24 mmmm of mercury that maintains the shape of the eye. If blockage of the drainage duct for aqueous humor causes this pressure to increase to about 50 mm of mercury, the condition is called glaucoma. What is the increase in the total force (in newtons) on the walls of the eye if the pressure increases from 24 mm to 50 mm of mercury? We can quite accurately model the eye as a sphere 2.2 cm in diameter. Express your answer in newtons.

Bird bones have air pockets in them to reduce their weight—this also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 42.3 g and its apparent mass when submerged is 2.61 g (the bone is watertight). (a) What mass (in g) of water is displaced? g (b) What is the volume (in cm3) of the bone? cm3 (c) What is its average density (in g/cm3)? g/cm3
