Chapters 18 & 19 Anatomy/Physiology Syllabus of the Cardiovascular System

Introduction: These chapters focus on the location, structure, and function of the heart, before moving on the blood vessels, their circulatory routes, and systemic circulation. An anatomy of the cardiovascular system will aid in its physiology. Next, control of circulation will be introduced by tracing a cardiac impulse through the conduction system. Finally, the means of measuring and evaluation blood pressure and pulse will be discussed.

Objectives:

1. List the primary organs of the cardiovascular system, and relate each organ or group of organs to the movement and/or dissection of blood flow in the system.
2. Describe the location, size, and position of the heart in the thoracic cavity.
3. List and discuss the 3 layers of the heart wall, heart cavities and the valves.
4. Trace blood through the heart
5. Trace blood through the coronary circulation
6. List the components of the heart conduction system.
7. Correlate structure of arteries, veins, venules, and capillaries with their function.
8. Trace the path of blood flow as it leaves the right side of the heart until it returns to the left side of the heart (pulmonary circulation).
9. Trace the blood from the heart to various locations of the body and return the blood to the heart.
10. Discuss the 6 structures characteristic of the fetal circulation
11. Discuss factors that influence heart rate.
12. Discuss several factors that influence heart rate.
13. Discuss the major events of the cardiac cycle.
14. Define pulse and factors that are responsible for its existence.
15. Identify where in the body the pulse can be felt.
16. Identify where pressure may be applied to stop arterial bleeding.
