Question

Quizplus · Accepted Answer

Regular exercise can increase the number of natural killer cells, which are a type of immune cell that helps to fight off viruses and cancer cells. There is not enough evidence to suggest that exercise can increase the number of red blood cells, and while exercise can have some benefits for lymphocytes, it does not necessarily increase their overall number. Basophils are a type of white blood cell that is involved in allergic reactions and inflammation, but there is no evidence to suggest that regular exercise increases their number.
