What is the function of the cardiovascular system?
Transportation of vital nutrients, such as oxygen, to the
cells and removal and transport of cellular wastes, such as carbon dioxide.
What organs make up the cardiovascular system?
Heart and the Blood Vessels
Discuss how the parasympathetic and the sympathetic nervous systems influence the heart?
Sympathetic Nervous System increases heart rate during fight or flight responses or from stress. The
parasympathetic nervous system decrease heart rate back to its normal beat.
HEART ANATOMY

Where is the heart located?
Medial to the lungs and anterior to the spine inside of the bony thorax.
5. What are the three main layers of the heart?
Describe them.
Epicardium – also called the visceral pericardium, outermost layer of the heart
Myocardium – cardiac muscle layer of the heart, thickest layer
Endocaridum – innermost layer of endothelium
