Blood Vessels of the Body
The Aorta
Ascending aorta – arises from the left ventricle; branches to form coronary arteries
Aortic arch – lies posterior to the manubrium; aortic branches form:
Brachiocephalic trunk
Left common carotid
Left subclavian arteries
Descending aorta – continues from the aortic arch
Thoracic aorta –extends from T5 – T12 vertebrae
Abdominal aorta – extends from T12 – L4 vertebrae
Divides into right and left common iliac arteries
Vena Cava
Superior & Inferior vena cava returns blood from the systemic veins to the heart
Superior Vena Cava – drains venous blood from head, arms, and chest (body regions superior
to the diaphragm)
Inferior Vena Cava – drains venous blood from the lower half of the body (body regions inferior
to the diaphragm)
Superior and inferior vena cava both empty into the right atrium of the heart
Vena Cava

Share the name of the accompanying artery
Superficial veins
Great saphenous vein empties into the femoral vein
Small saphenous vein empties into the popliteal vein
Veins Of The Right Lower Limb And Pelvis
