Name: Robert Christopher Date: 16/2/2011 ID: 0670000687 COMPARISON OF ARTERY AND VEIN Raw Data Table 1: Below are the results of the experiment completed through cutting down the vein and artery into a ring-like shape. A 10g-50g of mass is used to suspend the artery and vein; and measured it with a 1-meter ruler standing 90˚ on the table to distinguish how long it stretches with a specific mass weight. Average Length ± 0.05g/mm | Mass ± 0.05mm/g | Artery | Vein | | Trail 1 | Trial 2 | Average | Trial 1 | Trial 2 | Average | 0g | 393 | 377 | 385 | 370 | 374 | 372 | 10g | 392 | 376 | 384 | 368 | 372 | 370 | 20g | 391 | 375 | 383 | 366 | 370 | 368 | 30g | 390 | 374 | 382 | 364 | 368 | 366 | 40g | 389 | 373 | 381 | 362 | 366 | 364 | 50g | 388 | 372 | 38 | 360 | 364 | 362 | Data Presentation Table 2: Below are the results of the artery and vein’s length difference in mm. These results were known when the average results from the two trials were calculated. The results can be calculated with the following formula: "trial 1 + trial 2; then divide the result by 2 to get the average mean results”. Change in Length ±0.5mm/g | | Mass ±0.5mm/g | Artery | Vein | 0 | 0 | 0 | 10 | 0.1 | 0.2 | 20 | 0.2 | 0.4 | 30 | 0.3 | 0.6 | 40 | 0.4 | 0.8 | 50 | 0.5 | 1 | Graph The graph below shows the average length of the Artery with a ±1mm difference, whilst the average length of the Vein has a ±2mm difference. The Artery and the Vein was hanged with the use of 10g to 50g of mass to distinguish how long it stretches. Conclusion: Based on the results, it can now be determined that the vein stretches longer than the artery. By these results, it can be observed that the vein stretches ±2mm per 10g of mass, while the artery stretches ±1mm per 10g of mass. However, artery can endure high pressure than the vein. Arteries
