what is the driving force for blood flow? - pressure gradient
how does the body increase the blood vessel radius? - smooth muscle relaxation
what is blood measured in? - ml/min
what has the greatest effect on blood flow? - blood vessel radius
the diameter of the blood vessel is the same as - two times the radius of the blood vessel
the opening of the blood vessel where the blood flows is called the... - lumen
what do you think will happen to the flow rate if the radius is increased by 0.5 mm? - the flow rate
will increase
do you think a graph plotted with radius on the x-axis and flow rate on the y-axis will be linear (straight
line)? - no
what was the variable that we altered in the activity? - vessel radius
vessel radius and fluid flow - are directly proportional
after a heavy meal, when we are relatively inactive, we might expect blood vessels in the skeletal
muscles to be somewhat _________________ and the blood vessels in the digestive organs to be
somewhat ______________________ - constricted, dilated
what happens when you increased the flow tube radius, the fluid flow rate... - increases
