Physiology of the Heart

and Circulation

Basic Design and Function of the Learning Objectives
Cardiovascular System
Cardiac Cycle • Illustrate the heart and both pulmonary
Systole and peripheral vasculature. What is the
mean arterial pressure and oxygen con­
Diastole tent in each of these regions?
Heart Sounds and Murmurs • Using Figure 18‐3 and your knowledge
Imaging the Heart of cardiac anatomy, differentiate the
Electrical Activity of the Heart following: (1) periods of isovolumetric
Sinoatrial Node and Heart Rate contraction and isovolumetric relaxa­
Atrioventricular Node and Other Specialized tion; (2) periods of diastole or systole; (3)
the ejection or filling phases of the
Conductive Cells in the Heart cardiac cycle.
Electrocardiography and Arrhythmias • Integrate your knowledge from Chapters
Cardiac Output and Its Regulation 9 and 18 to resolve the mechanism of
Ventricular Filling and Stroke Volume cardiac myocyte action potential initia­
Cardiac Contractility and Stroke Volume tion and propagation from the sinoatrial
Structure and Function of Blood Vessels and atrioventricular nodes.
Microscopic Structure of Blood Vessels • Describe how cardiac preload and
afterload contribute to the work that
Function of Blood Vessels the heart must complete with each
Regulation of Arterial Blood Pressure and cardiac cycle.
Blood Volume • Differentiate the different components
Neural Reflexes of the vascular system and how their
Humoral Agents microscopic anatomy suits the role that
they play in the cardiovascular system.
Paracrine Agents • Illustrate the major organs and hormone
Cardiovascular Function During Exercise systems involved in regulating mean
and Hypovolemia arterial pressure and blood volume.
