Endothelium lining the internal heart chambers

In heart wall, simple squamous epithelium, fat, connective tissue

Outer serous pericardium, attached to the fibrous layer

Outer tough tissue connective, anchors & protects heart

film of serous fluid between layers of pericardium

sac membrane which encloses heart

Inner serous pericardium layer, aka epicardium

Circulation where deoxygenated blood from the heart is sent to the lungs to pick up O2

Circulation where oxygenated blood from the heart is pumped to the rest of the body

Thoracic region b/w the lungs housing heart & major vessels

Outer connective tissue that anchors a blood vessel

Innermost endothelium layer common to both arteries & veins

Circularly arranged smooth muscle in wall of blood vessel

Sympathetic NS causes lumen to decrease, BP to increase

Parasympathetic NS causes lumen to increase, BP to decrease

Oxygenated blood delivered to the myocardium

what are the only arteries that carry deoxygenated blood?

rounded or irregular muscular columns which project from the inner surface of the right and left ventricle of the heart

strong, fibrous connections between the valve leaflets and the papillary muscles, prevent the cusps from swinging back into the atrial cavity during systole.
