Chapter 30, Problem 5MCQ
Summary Introduction
Introduction:
The sinoatrial node is also called natural pacemaker is made of specialized bundle of neuron and is located in the upper part of right atrium. It is involved in the production of normal heart beats with a rhythm of about 70 beats per minutes for a healthy and resting heart.

She stands up suddenly after stretching and feels a bit light-headed. However, the lightheaded feeling passes quickly. What physiologic process occurred that resulted in the passing of her light-headed feeling? a.
