Systemic Circulation: Veins Return blood from body to right atrium Major veins • Coronary sinus (heart) • Superior vena cava (head, neck, thorax, upper limbs) • Inferior vena cava (abdomen, pelvis, lower limbs) Types of veins • Superficial • Deep • sinuses

 • External jugular veins • Internal jugular veins • Brachiocephalic veins
