Which granulocyte is the first to respond to an infection, has hydrolytic enzymes in its granules, and possesses the ability of phagocytosis?

• A. Basophil
• B. Eosinophil
• C. Neutrophil
• D. Macrophage

Answer: (C)

Verified step by step guidance

1. Understand the role of granulocytes in the immune response. Granulocytes are a type of white blood cell that play a crucial role in defending the body against infections.
2. Identify the characteristics of neutrophils. Neutrophils are the most abundant type of granulocytes and are typically the first responders to microbial infection.
3. Recognize the presence of hydrolytic enzymes in neutrophils. These enzymes are contained within the granules of neutrophils and help break down pathogens during an immune response.
4. Learn about the phagocytic ability of neutrophils. Phagocytosis is the process by which cells engulf and digest microorganisms and cellular debris, a key function of neutrophils in fighting infections.
5. Differentiate neutrophils from other granulocytes like basophils and eosinophils, which have different roles and characteristics in the immune system. Neutrophils are specifically known for their rapid response and phagocytic activity.
