  • Left common carotid artery
    A major artery branching from the aortic arch that supplies blood to the head and neck.
  • Brachiocephalic trunk
    The first major branch of the aortic arch that divides into the right subclavian and right common carotid arteries.
  • Left subclavian artery
    An artery branching from the aortic arch that supplies blood to the left arm.
  • Superior vena cava
    A large vein that returns deoxygenated blood from the upper body to the right atrium.
  • Aortic arch
    The curved portion of the aorta that gives rise to major arteries supplying the head, neck, and arms.
  • Ligamentum arteriosum
    A fibrous remnant of the fetal ductus arteriosus connecting the pulmonary trunk to the aortic arch.
  • Right pulmonary artery
    Carries deoxygenated blood from the right ventricle to the right lung.
  • Left pulmonary artery
    Carries deoxygenated blood from the right ventricle to the left lung.
  • Ascending aorta
    The initial section of the aorta rising from the left ventricle, supplying oxygenated blood to the body.
  • Pulmonary trunk
    The vessel that carries deoxygenated blood from the right ventricle to the pulmonary arteries.
  • Right pulmonary veins
    Veins that return oxygenated blood from the right lung to the left atrium.
  • Left pulmonary veins
    Veins that return oxygenated blood from the left lung to the left atrium.
  • Auricle of left atrium
    A small, ear-shaped muscular pouch on the left atrium that increases its capacity.
  • Left coronary artery
    An artery running in the coronary sulcus that supplies blood to the left side of the heart.
  • Right coronary artery
    An artery running in the coronary sulcus that supplies blood to the right side of the heart.
  • Anterior cardiac vein
    Veins that drain the anterior surface of the right ventricle directly into the right atrium.
  • Left ventricle
    The heart chamber that pumps oxygenated blood into the ascending aorta.
  • Right ventricle
    The heart chamber that pumps deoxygenated blood into the pulmonary trunk.
  • Right marginal artery
    A branch of the right coronary artery supplying the lateral right side of the heart.
  • Great cardiac vein
    A large vein running alongside the anterior interventricular artery, draining blood from the heart muscle.
  • Anterior interventricular artery
    Also called the left anterior descending artery; runs in the anterior interventricular sulcus supplying the front of the heart.
  • Small cardiac vein
    A vein that drains the right atrium and right ventricle into the coronary sinus.
  • Inferior vena cava
    A large vein that returns deoxygenated blood from the lower body to the right atrium.
  • Apex of the heart
    The pointed tip of the left ventricle directed downward, forward, and to the left.
