102 Cardiac and Circulatory Physiology

The Cardiovascular system is essential for life. PART 1 of this course includes: Anatomy of the Heart – gross and microscopic; Cardiac conduction system – the electrical system that controls the heart rhythm; External nervous system – influences on the heart; Peripheral vascular system – arteries, veins and lymphatic systems; PART 2 of this course will demonstrate how the anatomy enables function of the heart, including: Heart as a pump – the cardiac cycle, cardiac metabolism, electrical conduction, and control of the cardiac cycle; EKG’s – the electrical signals generated by the heart; Cardiac output – the volume of blood pumped, how it is measured, and what influences it; Arrhythmias – abnormalities of conduction; and Cardiac diseases.
