Pericardial Cavity - Fluid-filled space between the parietal pericardium (outer lining of heart) and the visceral pericardium (epicardium, the heart’s surface)

Cavidad pericardica

Myocardium - Thick, middle layer of the heart wall, composed of cardiac muscle that contracts to pump blood throughout the body.

Endocardio

Superior vena cava: Major, short vein that returns deoxygenated blood from the head, neck, arms, and chest to the right atrium of the heart

Vena cava superior

Aorta: main artery, supplies oxygenated blood to the circulatory system

aorta

Right Auricle: small, muscular pouch storing deoxygenated blood

Auricula derecha

Pulmonary trunk: Transports deoxygenated blood to the lungs for oxygenation

Tronco pulmonar

Inferior vena cava: the body’s largest vein, transports deoxygenated blood from the lower extremities, pelvis, and abdomen back to the right atrium of the heart

Vena cava inferior

Left/right atrium: left receives oxygenated blood from lungs

left/right ventricle:
