1. using plausible numbers, choose numbers for the following quantities for the two models given in the project, and give citations to sources that support your choices: the length of each type of vessel (which will also be the height change in part 2 for the stage consisting of that type of vessel). There are two types of vessels in structure A (aorta, capillary) and four types in structure B (aorta, artery, arteriole, capillary). The sum of the two types in A must be the same as the sum of the four types in B; that is, the height change from the heart to the top of the capillary must be the same for A as for B. The aorta in A does not need to have the same length as the aorta in B, and the capillaries in A do not need to have the same length as the capillaries in B. the diameter of the aorta, which is the same for both A and B. Do not give diameters of other types of vessels, since they will be calculated later. the volume flow rate of the blood (for instance, in mL/s) in the aorta, which is the same for both A and B. Do not give volume flow rate for the other types of vessels, since they will be calculated later. 2. Using the height changes from the first part, calculate the pressure difference in Pa between one end and the other for each type of vessel for each structure, considering only the pressure difference from height difference. You will have six answers total: aorta and capillary for A, and aorta, artery, arteriole, and capillary for B. Then convert each pressure difference to mm Hg.
