Question
Chapter 19, Problem 12RQ
Summary Introduction
To review:
The pathway of blood flow through the heart.Â
Introduction:
The heart, blood vessels, and the blood together form the circulatory system of the body. The blood is pumped by the heart and transported throughout the body with the help of blood vessels. The heart can be divided into four chambers, namely two auricles and two ventricles through which the blood flows.

Scenario: Michelle Q. experienced a recent chest injury, and now her ventricular contractions pump less blood into her pulmonary arteries & aorta as they did during her days as an Olympian. The cardiologist tells her this will lower her cardiac output, but doesn't elaborate. Michelle is a curious sort and would like you to tell her why her cardiac output is going to decrease. You tell Michelle….
Fill in the table below by indicating the organ, region or vessel that the named vessel receives blood from, and the organ, region or vessel to which it delivers blood (see example for aorta and coronary arteries). If you’re doing it right, both columns will have the same answer. You will need to refer to the images in your textbook and lab models to do this.
