6 Questions
Which of the following factors affects cardiac physiology by influencing the degree of stretch on the ventricular walls prior to contraction?
Afterload
Which term refers to the amount of blood pumped by the heart per minute?
Cardiac output
Which of the following factors affects stroke volume by influencing the amount of blood in the ventricles before contraction?
Preload
What is the normal cardiac cycle, and what are the four factors affecting cardiac physiology?
The normal cardiac cycle includes atrial contraction, ventricular contraction, and relaxation. The four factors affecting cardiac physiology are preload, afterload, cardiac output, and stroke volume.
What is preload, and how does it affect cardiac physiology?
Preload is the degree of stretch on the ventricular walls prior to contraction. It affects cardiac physiology by influencing the force of contraction and stroke volume.
What is afterload, and how does it impact perfusion?
Afterload is the resistance against which the heart must pump to eject blood from the ventricles. It impacts perfusion by affecting cardiac output and the amount of oxygen and glucose supplied to the tissues.
Test your knowledge on the normal cardiac cycle and the factors that affect cardiac physiology. This quiz will cover concepts such as preload, afterload, cardiac output, and stroke volume, and their impact on perfusion, including oxygen and glucose supply. Sharpen your understanding of the intricate workings of the heart and its crucial role in maintaining overall health.
