In this problem, you apply the Continuity Equation in 3 ways.

In this problem, you apply the Continuity Equation in 3 ways. Artery Region 2 Region 1 Keep 3 decimal places. (a) As shown in the above figure, a major artery (region 1) with a cross-sectional area of 1.00 cm2 branches into (region 2) 18 smaller arteries, each with an average cross-sectional area of 0.48 cm2. Find the ratio of v,/ V, (in decimal), where v, is the average speed of blood flow in the major artery (region 1), and v, is the average speed of blood flow in the smaller arteries (region 2). Enter a number Submit (5 attempts remaining) Region 2 Venule capintaries Region 1 (b) As shown in the above figure, as blood passes through the capillary bed in an organ, the capillaries (region 1) join to form venules (small veins)(region 2). If the blood speed increases by a factor of V/V = 4, and the total cross-sectional area of the venules A, is 10.40 cm2, what is the total cross- sectional area (in cm2) of the capillaries A, feeding these venules? Keep 2 decimal places. Enter a number Submit (5 attempts remaining) cm?
