Name two functions of arterioles.
Step by step
Solved in 2 steps
- What is the only autonomic innervation of most arterioles?Let’s say an arteriole dilates to 50% greater than its original size (i.e., the new radius of the arteriole is 1.5 times the original radius). How does the blood flow rate through the arteriole change after dilation? (Hint: You do not need to know the exact values for viscosity, arteriole length, or pressure gradient in order to answer this question.)while a typical ECG tracing is shown, many things can alter and be perfectly normal for that individual. list some of the factors that change the standard tracing:.......?
- What is the structure of the arterioles?Assume that the arteriole has undergone a change in morphology that resulted in shortening and increased diamter of the arteriole. Which of the following will occur? Choose one. -Reduced flow rate -Venous bypass -Increased arteriolar resistance -Reduced venous return -Reduced arteriolar resistanceWhat is the function of the arterioles?
