The Heart Superficial Anatomy

Pericardial sac
a conical sac of fibrous tissue which surrounds the heart and the roots of the great blood vessels

Pericardial cavity
located between the heart and the pericardial sac; contains pericardial fluid

Parietal pericardium
lines the paricardial sac

Visceral pericardium (epicardium)
covers the heart

Base
region where the major arteries an veins connect

Apex
tip of the heart

Coronary sulcus
groove between the atria and the ventricles

Interventricular sulcus
depression between the ventricles

Right atrium
recieves blood from the systemic circuit

Right ventricle
discharges blood into pulmonary circuit

Left atrium
recieves blood from the pulmonary circuit

Left ventricle
discharges blood into systemic circuit

Superior vena cava
returns blood from upper systemic organs to the right atrium

Inferior vena cava
returns blood from lower systemic organs to the right atrium

Pulmonary trunk
carries blood to the lungs from the right ventricle

Pulmonary veins
returns blood from the lungs to the left atrium

Ascending aorta
carries blood to systemic organs from the left ventricle

aortic arch
a bend in the aorta that allows vessels to branch to the upper body before descending to the lower body

Ligamentum Arteriosus
remnant of the fetal vascular connection between the pulmonary trun and the aortic arch
