In the body, what are three major factors that govern resistance in blood flow?
Blood vessel radius, blood vessel length and blood viscosity
A significant build-up of lipid deposits in a person's arteries will ____________ blood flow and ___________ resistance?
Poiseuille's equation states that the __________ has the strongest effect on blood flow?
Radius of the blood vessel
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.
In which of the following would the most resistance be observed?
Blood with a high hematocrit and in a vessel with a small radius
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.
Laminar flow describes the quick, rough manner in which blood flows along the length of the vessel.
