Anatomy & Physiology II
Capillary dynamics problem set
Students are to complete the following problems and then go to Assignments on Blackboard to submit their answers to the instructor. Answers need to be submitted before the next class meeting.
1. Given the following:
OPc = 27 mm
HPc = 34 mm
OPif = 1.5 mm
HPif = 0.5 mm Net filtration = ____ mm
2. In question 1, is filtration or reabsorption occurring?
3. Given the following:
OPc = 27 mm
HPc = 16 mm
OPif = 1.5 mm
HPif = 0.5 mm Net filtration = ____ mm
4. In question 3, is filtration or reabsorption occurring?
5. In a capillary under normal conditions, which force is primarily responsible for filtration?
6. In a capillary under normal conditions, which force is primarily responsible for reabsorption?
7. Given the following:
OPc = 26 mm
HPc = 40 mm
OPif = 1 mm
HPif = 0 mm Net filtration = ____ mm
8. Mr. B has liver failure and is not synthesizing albumin properly. His serum albumin level is 2.1 g/dl (normal = 4 - 6 g/dl). Which one of the forces that determine capillary dynamics is being affected most by this condition?
9. Inflammation commonly results in increased permeability of blood capillaries in the particular inflamed tissue leading to localized edema. Which factor that plays a role in capillary dynamics is the most likely cause of the edema? Note that we are considering a localized not systemic effect here.
