Cardiovascular System

What is the pulmonary pathway?

Heart to lungs to heart (getting oxygen)

What is the systemic pathway?

Heart to body to heart (use oxygen)

What is the cavity within the thoracic cavity where the heart is located?

Pericardial cavity

The tough, outermost covering of the heart is a sac known as the fibrous…

pericardium

the serous membrane of the heart is made up of the outer layer called

parietal paricardium

the inner layer of the serous membrane is called the

visceral pericardium

the space in-between these two layers is filled with

serous fluid / pericardial fluid

the 3 layers of the walls of the heart (outer to inner)

epicardium, myocardium, endocardium

the layer of the heart wall that contains cardiac muscle tissue is the

myocardium

the inner lining of the heart walls composed of a single layer of epithelial tissue is called the

endocardium

the blood vessels that oxygenate and nourish the heart itself are the

coronary arteries

the chambers that receive blood are the

atria

the chambers that pump blood out of the heart are the

ventricles

the 2 major veins that return deoxygenated blood to the heart from the systemic circuit are the

superior and inferior vena cava
