Recall the three layers of muscles in the wall of the heart. which lists these muscles in order from closest to the blood inside the chamber to farthest from the blood?

The cardiac wall contains three layers: epicardium, myocardium and endocardium.

Explanation:

The epicardium, the outermost layer of the heart, also has a large amount of adipose tissue. It is the same as the visceral layer of the serous pericardium.

 The myocardium, located below the epicardium, is the cardiac muscle tissue as such, responsible for pumping the blood through the circulatory system through contraction.

 The endocardium is the membrane that covers the inside of the heart. This membrane surrounds the inside of blood vessels, transporting blood through a continuous tunnel of endothelial cells throughout the cardiovascular system.

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs. 

explanation:

a physical change is being made.
