Explain of Pulmonary Pathology

70.Lung, pulmonary thromboembolus, low power microscopic

This is the microscopic appearance of a pulmonary thromboembolus in a large pulmonary artery. There are interdigitating areas of pale pink and red that form the "lines of Zahn" characteristic for a thrombus. These lines represent layers of red cells, platelets, and fibrin which are layed down in the vessel as the thrombus forms.
