When leukocytes or enzymes absorb all or part of a thrombus, what process has occurred?

The process described in this scenario, where leukocytes or enzymes absorb all or part of a thrombus, is known as resolution. This term refers to the body's ability to clear away the remnants of a thrombus, either through the action of immune cells like leukocytes or through enzymatic degradation. During resolution, the thrombus undergoes a breakdown, allowing for the restoration of normal blood flow and the removal of any obstructive material that was previously present. This is a critical step in the healing process as it helps to restore homeostasis and prevent complications associated with excessive clot formation.

In contrast, organization would refer to the process where the thrombus leads to the formation of granulation tissue as part of healing; propagation relates to the growth of the thrombus itself, leading to an increased obstruction; and revascularization involves the formation of new blood vessels to restore blood supply to a tissue. Hence, resolution appropriately captures the active breakdown and absorption of the thrombus by leukocytes and enzymes, indicating a return to normal physiological function.
