Pulmonary arteries
A ___________ is one of two large chambers toward the bottom of the heart that collect and expel blood received from an atrium.
Ventricles
What are the 2 layers of the Pericardium
Parietal and Visceral/ pericardium (epicardium)
this is the inner layer of the wall of the heart
Endocardium
_______carry blood toward the heart
Veins
The _________________ deliver oxygenated blood from the lungs to the left atrium of the heart.
Pulmonary veins
The aorta is the main artery that carries blood away from your heart to the rest of your body.
Aorta
this fluid acts as a lubricant for the movement of the heart, reducing friction as the heart pumps blood
Serous fluid for heart
this is the outside layer of the wall of the heart
Epicardium
________receives oxygen-poor blood from the body and pumps it to the right ventricle
right atrium
___________________includes a vast network of arteries, veins, and lymphatics that function to exchange blood and other tissue fluids between the heart, the lungs, and back.
Pulmonary circulation
the________of the two venae cavae, the great venous trunks that return deoxygenated blood from the systemic circulation to the right atrium of the heart
Superior vena cava
this is the deep down layer next to the heart
Visceral pericardium
this is the middle layer of the wall of the heart
Myocardium
________ receives oxygen-rich blood from the lungs
left atrium

Pulmonary trunk
The __________ carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.
inferior vena cava
this outside layer that lines the inner surface of the fibrous
Parietal pericardium
the myocardium is mostly what type of muscle?
cardiac muscle
_________pumps the oxygen-poor blood to the lungs
right ventricle
