    ### Response:
    Congenital pulmonary lymphangiectasia is a rare developmental disorder present from birth that affects the lungs. Infants with this condition have abnormally widened lymphatic vessels within the lungs. The lymphatic system, which helps the immune system protect the body against infection and disease, consists of a network of tubular channels that drain a thin watery fluid known as lymph from different areas of the body into the bloodstream.
