Which of the following statements are true of the pulmonary circulation?
I.It is a low-resistance system compared with the systemic circulation.
II.Its pressures are lower even though it receives the same cardiac output as the systemic circulation.
III.The resistance to blood flow in the pulmonary circulation is approximately one-fourth as great as it is in the systemic circulation.
IV.The resistance to blood flow in the pulmonary circulation is approximately one-tenth as great as it is in the systemic circulation.

Figure 6-1 shows that the pulmonary circulation is a low-pressure, low-resistance system compared with the systemic circulation. The lower resistance in the pulmonary circulation is implied by the fact that its pressures are lower even though it receives the same cardiac output as the systemic circulation. The resistance to blood flow in the pulmonary circulation is approximately one-tenth as great as it is in the systemic circulation.
