Learning Objectives: Activities 1-4 * To understand how blood vessel radius affects blood flow rate. * To understand how vessel radius is changed in the body. * To understand how to interpret a graph of blood Bessel radius versus blood flow rate. * To understand how blood viscosity affects blood flow rate. * To list the components in the blood that contribute to blood viscosity. * To explain conditions that might lead to viscosity changes in the blood. * To understand how to interpret a graph of viscosity versus blood flow. * To understand how blood vessel length affects blood flow rate. * To explain conditions that can lead to blood vessel length changes in the body. * To compare the effect of blood vessel length changes with the effect of blood vessel radius changes on blood flow rate. * To understand how blood pressure affects blood flow rate. * To understand what structure produces blood pressure in the human body. * To compare the plot generated for pressure versus blood flow to those generated for radius, viscosity, and length.
Data: * Activity 1 Effect of Blood Vessel Radius on Blood Flow Rate Flow (ml/min) | Radius (mm) | Viscosity | Length (mm) | Pressure (mm Hg) | 4.0 | 1.5 | 1.0 | 50 | 100 | 12.6 | 2.0 | 1.0 | 50 | 100 | 30.7 | 2.5 | 1.0 | 50 | 100 | 63.6 | 3.0 | 1.0 | 50 | 100 | 117.8 | 3.5 | 1.0 | 50 | 100 | 201.0 | 4.0 | 1.0 | 50 | 100 | 321.9 | 4.5 | 1.0 | 50 | 100 | 490.6 | 5.0 | 1.0 | 50 | 100 |
* Activity Questions 1. Describe the relationship between vessel radius and blood flow rate? Vessel radius has a direct relationship with blood flow. As blood vessels constrict (vasoconstriction), blood flow is decreased. As blood vessels dilate (vasodilatation), blood flow is increased. 2. In this activity you altered the radius of the flow tube
