Cardiac Cycle Part 3 - Ejection, Isovolumetric Relaxation, and Filling

The video tutorial covers the cardiac cycle, focusing on phases like isovolumetric contraction, ejection, and relaxation. It explains how pressure changes in the heart chambers and vessels drive blood flow, and how these phases are represented in an EKG. The tutorial also discusses normal blood pressure values and their significance, concluding with the ventricular filling phase that resets the cycle.

What happens to the blood pressure in the aorta during the ejection phase?

Describe the significance of the T wave in the EKG during the cardiac cycle.

What occurs during the isovolumetric relaxation phase?

How does the cardiac cycle ensure continuous blood flow throughout the body?
