Guided Learning: Blood Pressure Regulation

Guided learning questions provide a systematic approach to learning by using a sequencing of the questions similar to how a topic would unfold in a traditional textbook. The student is encouraged to go not only to the initial link associated with each tutorial question, but also to use embedded hyperlinks to expand upon the physiological concepts associated with the question.

At the end of the guided learning questions, there is a link to an external website (testmoz.com) that has multiple choice and true/false questions that are associated with the topic. When the quiz results are given to the user after taking the quiz, links are provided back to specific cvphysiology.com pages to assist learning. Users need to register (free) on the testmoz.com site to access the quiz questions for the tutorial. No personal information is available to cvphysiology.com apart from the user provided login name and analysis of user performance on the quiz questions. This feedback is used to improve cvphysiology.com content and quiz questions.

Guided Learning

1. How do changes in cardiac output and systemic vascular resistance influence mean arterial pressure?
2. What is systemic vascular resistance, and how is it calculated?
3. What is the distribution of blood pressure and volume in the vascular network?
4. How do changes in blood volume affect arterial pressure?
5. What are systolic and diastolic aortic pressures?
6. What is arterial pulse pressure, and what factors cause it to increase or decrease?
7. What is vascular tone?
8. What intracellular mechanisms regulate vascular smooth muscle contraction and relaxation?
9. What are the primary adrenergic and cholinergic receptors that regulate vascular smooth muscle function?
10. What are the major signal transduction mechanisms that regulate vascular smooth muscle contraction and relaxation?
11. What is the role of autonomic nerves in regulating arterial pressure?
12. How do arterial baroreceptors regulate arterial pressure?
13. What roles do the following humoral factors play in regulating arterial pressure?
