Thorax Lab 2 Module 1

OBJECTIVES:

1.2.1 Trace the flow of blood through the right side of the heart, identifying the internal structures of the right atrium and ventricle, the associated valves, and the surface projections of these valves on the chest wall.

1.2.2 Identify the anatomic locations of the key ecomponents of the heart's impuls- conducting system.

1.2.3 Trace the flow of blood through the left side of the heart, identifying the internal structures of the left atrium and ventricle, the associated valves and the surface projection of these valves on the chest wall.

1.2.4 Compare the circulatory pathway of blood in fetal life with that of the adult circulation, focusing on the differences in the heart and great vessels.

Let's trace the flow of blood through the heart, starting with the venous return on the right side.

	Begin by adding the superior and inferior vena cava, which returns deoxygenated blood from the body to the heart.
	Add the right atrium, the receiving chamber for systemic venous blood.
	Add the coronary sinus, a third vessel that drains into the right atrium. The coronary sinus returns venous blood from the myocardium.
