The white blood cell that releases histamine and other inflammatory chemicals is:
a. Basophil
b. Neutrophil
c. Monocyte
d. Eosinophil

Verified step by step guidance

Step 1: Understand the role of different white blood cells (WBCs) in the immune response. Each type of WBC has a specific function in defending the body against pathogens or in inflammatory processes.

Step 2: Recall that histamine is a chemical involved in inflammation and allergic reactions, causing blood vessels to dilate and become more permeable.

Step 3: Identify which WBC is known for releasing histamine and other inflammatory chemicals. This WBC plays a key role in initiating inflammation and allergic responses.

Step 4: Review the functions of the options: Basophils release histamine; Neutrophils are primarily phagocytic cells that engulf pathogens; Monocytes differentiate into macrophages and dendritic cells; Eosinophils combat parasitic infections and modulate allergic responses.

Step 5: Conclude that the white blood cell responsible for releasing histamine and other inflammatory chemicals is the Basophil.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Basophils

Basophils are a type of white blood cell involved in immune responses, particularly allergic reactions. They release histamine and other chemicals that cause inflammation, helping to defend against pathogens and trigger symptoms like swelling and redness.

Histamine and Inflammatory Chemicals

Histamine is a chemical released by certain immune cells that increases blood vessel permeability, leading to inflammation. This process helps isolate and eliminate pathogens but also causes common allergy symptoms such as itching and swelling.

Types of White Blood Cells

White blood cells (leukocytes) include various types like neutrophils, monocytes, eosinophils, and basophils, each with distinct roles. Understanding their functions is essential to identify which cells release specific chemicals during immune responses.
