Topic 1 Deliverable 1A. Develop a hypothesis to predict the effect of an increase in blood viscosity on blood pressure, then test your hypothesis as follows. Click and drag on the slider to increase blood viscosity. Hypothesis: increased blood viscosity increase blood pressure.

What happened to MAP? Does this make sense to you? Explain your observations and relate them to your hypothesis. Use the slider to decrease blood viscosity and observe what happens to MAP. When increased the blood visosity, the line of the total peripheral resistance goes up obviously. As the blood increases in viscosity, the heart is required to increase the amount of pressure it takes to push the blood through the vasculature; thus the blood pressure increases CardioLab Lab Notes for DeVry Biology ---------------------------------------------------------------------- Time MAP Pulse Stroke Vol TPR Blood Vol =================================================================
