When we studied the cardiovascular system, we conducted a lab determining blood viscosity. Blood is carried through our bodies in two different ways, through arteries and veins. Arteries carry oxygenated blood to the bodies cells, muscles, organs, and veins bring un oxygenated blood back to the heart to be recycled and the process starts all over.
Believe it or not, but arteries and veins vary in size and the structure of them. The differences between arteries and veins is arteries have thick elastic muscular walls, there is an absent in the valves, and the blood flow is under high pressure. Veins on the other hand have thin non elastic walls, valves are present to prevent backward blood flow, and the blood travels back to the heart under low pressure.
Blood viscosity is the thickness and stickiness of blood. It is a direct measure of the ability of blood to flow through the vessels.
The lab conducted by my lab partner and I observed the relationship between the viscosity of the blood on the resistance of blood flow, by looking how fast it moved. to set up this lab we used two 20inch, identical tubes with the same diameter, and the two different solutions: water (less viscous) and a watery soap dilution ( more viscous). The same amount of the two solutions were poured into the tubes at the same time as we used a stop watch to record the time. To find the top speed, we used the speed/distance formua, the water solution time was recorded 33 seconds, and the soapy solution was recorded 30 seconds. The final speed for the water was 60in/second and the soapy solutionwas 66in/second. The reason being is that when you wash your hands with soap and water you feel the less resistance. That seemed to be the case here, which is why the watery soap solution was faster.
