Question
Chapter 15, Problem 33RQ
Summary Introduction
To determine: The fate of the flow of blood by using a mathematical equation, if the vessel's diameter increases from 2 millimeters to 4 millimeters.
Introduction: An absolute pressure can be defined as the zero-referenced against a strict vacuum. It strictly equals to the gauge pressure. A pressure gradient helps in the determination of the direction and rate of the pressure.

Examine one of the consequences of branching with a simple model shown in the figure.
Assume that there are two blood-flow circuits, which are identical except that one of the circuits has a single vessel, whereas the other has two identical vessels in parallel.
a.If the resistance of a single vessel is R, what is the overall resistance of the two vessels in parallel?
b.If each of the circuits carries the same flow rate, which has the larger pressure drop? Comment on the result.
Capillary filtration plays a vital role in the exchange of fluids between the circulatory system and tissues
A. Consider a scenario where the hydrostatic pressure in the capillary bed is 40 mmHg, the osmotic pressure in the capillary is 25 mmHg, and the interstitial fluid hydrostatic pressure is 5 mmHg. Calculate the net filtration pressure in this situation.
B. Determine the direction of fluid movement across the capillary wall

- Given: Capillaries are where the magic of gas diffusion happens. Capillaries are approximately 5-10 µm in diameter. Let’s pick an average value of 7.5 µm. A normal value of the diameter of an aortic artery is 15 mm. a. How many capillaries would it take to have the same cross-sectional area as a single aortic artery? b. Assuming constant fluid flow through a single aortic artery and a capillary network with the same cross-sectional area, how will the resistance to flow compare to both? (Answer a and b)arrow_forwardAs blood flows from the aorta to the arteries, arterioles, and capillaries and through the venous circulation, it encounters various resistances to flow, which results in pressure drops. Using the table, calculate the resistance for an artery and a capillary.

- An electromagnetic flowmeter can measure the speed of blood flow through an artery during surgery. When the meter is turned on, positively- and negatively-charged ions in the blood tend to accumulate near opposite walls of the artery (as shown in the diagram below). This causes an electric field within the artery. + + + + + + + + + + blood flow (a) Sketch the electric field set up by the grouping of ions. (b) What is the magnitude of the force on an ion, with charge of *q, flowing along the middle of the artery, due to the electric field within the artery? Express your answer in relation to the magnitude of the electric field. (c) What is the direction of this force?
