2. Thrombosis may lead to which of the following?
a development of new vessels that re-establish blood flow within the thrombus AND complete removal of thrombus by the action of proteolytic enzymes
3. During the organization process by which granulation tissue replaces a thrombus in a blood vessel, there may be a development of new vascular channels through the old thrombus. THsi process is referred to as

patent foramen ovale
systemic arterial thromboemboli most commonly arise from the
28. Which of the following sites is least likely to lead to pulmonary emboli?
portal vein
