Dental students healed more slowly from punch wounds received three days prior to a major exam than from punch wounds received during their summer vacation. the slower healing prior to a major exam is best explained by the students' temporarily reduced production of

lymphocytes

Explanation:

Lymphocyte is a type of cell that is part of the body's immediate defense, acting against cancer cells and viral infections. Also, these cells are very important in wound healing. Slower healing of an injury is best explained by temporarily reduced lymphocyte production.

The concentration of these cells in the blood depends on the individual's physical condition: in cases of immunodeficiency, the concentration is low (lymphopenia); when there are infections or rejection of transplants, it increases (lymphocytosis). Lymphocyte count is a widely used test for monitoring diseases and infections such as those caused by HIV.
