A patient sustains a laceration of the thigh in an industrial accident. Which step in the inflammatory process will the patient experience first?
a. Cellular inflammation
b. Exudate formation
c. Tissue regeneration
d. Vascular response
D
Immediately after the injury, the vascular response occurs. Blood vessels at the site constrict to control bleeding. After the injured cells release histamine, the vessels dilate, causing increased blood flow to the area. During the next phase, known as the cellular response phase, white blood cells migrate to the site of injury. In the exudate formation phase, the fluid and white blood cells move from circulation to the site of injury, forming an exudate. Tissue regeneration occurs in the healing phase.
