Practice Question

Which of the following usually accounts for the smallest percentage of leukocytes in a blood sample?

Answer Choices:

Correct Answer:

Basophils.

Rationale:

⮞ Basophils are the least common type of white blood cell, typically making up less than 1% of the total leukocyte population.

⮞ Their primary role is to release histamine and heparin during allergic reactions and inflammatory responses.

⮞ Other leukocytes such as neutrophils, monocytes, and eosinophils are more abundant and perform broader immune functions.

⮞ Because basophils are rare and specialized, they account for the smallest percentage of leukocytes in blood samples.
