Textbook Question

More than one choice may apply.
The leukocyte that releases histamine and other inflammatory chemicals is the
a. Basophil
b. Monocyte
c. Eosinophil
e. Neutrophil

Verified step by step guidance

Identify the function of each type of leukocyte listed in the options.

Understand that histamine is a chemical involved in inflammatory responses.

Recall that basophils are known for releasing histamine and other chemicals during allergic reactions and inflammation.

Consider the role of monocytes, eosinophils, and neutrophils in the immune response and their typical functions.

Determine which leukocyte is primarily associated with the release of histamine and other inflammatory chemicals.

Key Concepts

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

Leukocytes

Leukocytes, or white blood cells, are crucial components of the immune system, responsible for defending the body against infections and foreign substances. They are categorized into different types, each with specific functions, including phagocytosis, antibody production, and the release of inflammatory mediators.

Basophils

Basophils are a type of granulocyte that play a key role in the inflammatory response. They release histamine and other chemicals that contribute to inflammation and allergic reactions, making them essential for the body's response to allergens and pathogens.

Inflammatory Response

The inflammatory response is a biological reaction to harmful stimuli, such as pathogens or tissue injury. It involves the activation of immune cells, release of signaling molecules, and increased blood flow to the affected area, leading to symptoms like redness, heat, swelling, and pain.
