Consider this: Blood is flowing down an artery and that artery bifurcates (branches in two directions). The first branch maintains the same radius as the artery before the bifurcation. The second branch is composed of many smaller vessels that together, equal the total radius of the first branch. What is true about the two branches?
The second branch has more resistance than the first.
Clinical hypothetical: You are an ER physician at UMC in Lubbock, TX. A patient presents with complaints of itching and headaches. The patient also has a severe bruise on their leg that may indicate a deep vein thrombosis (DVT). Standard protocol dictates that you run blood tests. The test indicates an extremely high hematocrit in addition to the somatic symptoms. Based on the symptoms and what you've learned in this lab, what is a possible diagnosis.
