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.

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
Nizatidine injection (25 mg/mL) is supplied in 4-mL vials. The prescription states that for continuous infusion 'dilute 300 mg in 150 mL and give at a rate of 10 mg/hour'. If this procedure is adopted, calculate: (a) how many vials of nizatidine injection will be required (b) the flow rate (in mg/hour).
