Fill in the Blank QuestionFill in the blank question.Neutrophils, eosinophils, and basophils are categorized as granulocytes since they contain cytoplasmic .

The correct answer to fill in the blank is "granules."

Explanation

Granulocytes are a type of white blood cell that are characterized by the presence of granules in their cytoplasm. These granules are small particles that contain various enzymes and chemicals, which are crucial for the cells' functions in the immune response, such as fighting infections and responding to allergens.

• Neutrophils: The most abundant type of white blood cells, they play a key role in combating bacterial infections. Their granules contain enzymes that help digest microorganisms.
• Eosinophils: These are involved in responses to parasitic infections and in allergic reactions. Their granules contain toxic proteins that can damage parasites.
• Basophils: The least common granulocytes, they are involved in inflammatory responses and contain histamine, which is important in allergic reactions.

Knowing these categories helps in understanding the body's immune system and how it responds to different types of pathogens and stimuli.
