Which leukocytes release histamine during the inflammatory response?

Answers

Answer:

Explanation:

as part of an immune response to foreign pathogens, histamine is produced by basophils and by mast cells found in nearby connective tissues. Histamine increases the permeability of the capillaries to white blood cells and some proteins, to allow them to engage pathogens in the infected tissues.

Final answer:

Basophils release histamine during the inflammatory response.

Explanation:

Basophils are a type of leukocyte that release histamine during the inflammatory response. Basophils are a type of white blood cell found in the bloodstream and are involved in the body's immune response. They release histamine as part of an allergic or inflammatory reaction, which causes blood vessels to dilate and increase blood flow to the affected area.

Basophils, alongside mast cells, are key players in the early stages of immune responses. Their histamine release contributes to the body's defense mechanisms, but it can also lead to allergic reactions when triggered by harmless substances, resulting in symptoms like itching, swelling, and congestion.
