Textbook Question
Chapter 17, Problem 7RQ
Trace the path of the pulmonary circulation. About how much blood is found here at any given moment? What is a typical arterial blood pressure for the pulmonary circuit, and how does this pressure compare with that of the systemic circulation?

MAP of the pulmonary system is 21 mmHg, Left Atrial Pressure is 3mmHg, and Flow is 5625ml/min. What is the resistance of the pulmonary circuit? Would this be higher or lower resistance than the systemic circuit? Why do you think so?
Using a flow diagram (arrows), describe the pathway of the pulmonary circulation. Indicate the relative amounts of oxygen and carbon dioxide in the vessels involved.
List the variables that increase the release of oxygen (by decreasing the affinity of oxygen to hemoglobin) as blood passes through systemic capillaries.
