- The main artery whose cross-sectional area is (1 cm) branches into 5 smaller arteries. Each of these arteries has an average cross-sectional area of (0.4 cm2). By what factor will the rate of blood flow decrease when it passes through those branches? arterialarrow_forwardFor each row, select the correct bolded term for arteries and veins... for example is the pressure in arteries HIGH or LOW? The pressure in veins is UICH ar OW? For Blank 5 NUte. une pressure and flow of each vessel (with a *) cause the lower row features. For example, vessel structure is adapted to compensate for high pressure or low pressure. Arteries Veins *Pressure- high or low? *Pressure- fluctuates or constant? *Flow- good or poor? Diameter- wide or narrow? Tunica media- thick/thin? Valves present- yes or no? Skeletomuscle pump improves flow – Yes or no? Some of these vessels have a lot of elastin - Yes or no?arrow_forwardThe largest cross-sectional area in the total circulation and lowest blood flow velocity is found in: A. The Aorta. B.

- Capillaries are very narrow and leaky. Which functions do those characteristics enable? Pick ALL answers that apply. 1.blood moves slowly 2.materials can diffuse out of the capillary easily 3.materials can diffuse into the capillary easily 4.the capillary can expand and contract very strongly 5.blood can't flow in the wrong direction because of the valvesarrow_forwardI know that the pressure of the blood (hydrostatic pressure) is higher than the pressure of interstitial fluid at the arteriole end of the capillary bed. What about the partial pressure of oxygen? Is it higher in the interstitial fluid arteriole end than the blood? But then would this mean that there is less of a volume of oxygen in the arteriole end?arrow_forwardA person had a heart attack involving a large part of the ventricular heart muscle.
