umbilical artery
branch of the umbilical vein that enters directly into the inferior vena cava, bypassing the portal system of the liver
ductus venosus
opening within the interatrial septum that acts to bypass the pulmonary circulation
foramen ovale
shunt between the pulmonary trunk and aorta; bypasses pulmonary circulation
ductus arteriosus
consist of lymphatic cells within an extracellular connective tissue matrix

small structures containing lymphatic tissue (phagocytic cells, etc.) through which lymph is filtered
lymph nodes
located on the left side of the abdominal cavity functions include cleansing the blood of retired old red blood cells
spleen
located in the thoracic region deep to manubrium, visible in childhood, atrophies in adulthood; functions in the immune system
thymus
lymph tissue located at the back of the throat
tonsils
