Chapter 13-3^rd ed. Or Chapter 14-2^nd ed. Blood Vessels and Circulation

o List the names and general functions of the blood vessels

o Discuss the histology of the walls of the arteries and veins. (fig. 13-1 -3^rd ed.) or (fig 14-1- 2^nd ed.)

o Compare the different types of arteries

o Explain how capillaries are adapted for gas exchange

o Discuss the significance of the valves found in some of the veins.

o Discuss 2 factors that affect the blood flow rate through the capillaries

o Describe the factors that contribute to blood pressure

o Discuss the major homeostatic mechanisms of blood flow and blood pressure control

Name, locate and give the functions of the major blood vessels as described in “Major Blood Vessels of the Human Body”. (available on the course web site). Bring a copy to your lecture and Cardiovascular System tutorial.
