Which of the following correctly compares the factors involved in bulk flow of fluid in systemic and pulmonary capillaries?

Question

Quizplus · Accepted Answer

The hydrostatic pressure inside pulmonary capillaries is lower than in systemic capillaries because the pulmonary circulation is a low-pressure system compared to the systemic circulation. This lower pressure results in less filtration of fluid out of the capillaries and into the surrounding tissues. The other choices are incorrect: A is incorrect because protein oncotic pressure inside pulmonary capillaries is typically lower than in systemic capillaries; B is incorrect because both the pulmonary and systemic circulations have lymphatic vessels to remove excess interstitial fluid; D is incorrect because protein oncotic pressure in interstitial fluid is typically very low; and E is incorrect because the Starling's forces are balanced in both pulmonary and systemic capillaries, with slight favoring towards reabsorption in systemic capillaries due to their higher hydrostatic pressure.
