Objectives Chapter 14: The Cardiovascular System: Blood Vessels, Blood Flow and Blood Press As you work through the learning activities and quizzes for this chapter, keep the following learning objectives in mind: Describe the physics of blood flow through blood vessels. Explain the concepts of pressure gradients and resistance. Describe the anatomy of the vasculature and explain the basic functional properties of the different types of blood vessels. Explain the role of arterioles in varying resistance. Describe how intrinsic control of vascular resistance regulates blood flow to organs. Explain the role of extrinsic control of arteriole radius in determining mean arterial pressure.

Unformatted text preview: • Explain how material is exchanged between blood and interstitium. Describe the forces that cause bulk flow of fluid across capillary walls. • Explain how mean arterial pressure influences blood flow to individual organs and to the entire systemic circuit, and identify the factors that determine mean arterial pressure. • Describe what the arterial baroreceptor reflex is, and explain how it regulates mean arterial pressure. • Describe how changes in arterial carbon dioxide levels, body heat, and exercise affect cardiovascular function and mean arterial pressure....
