Answer:

Mast cell

Step-by-step explanation:

Number 1 in the diagram represents a mast cell. Mast cells are a type of white blood cell that plays a key role in the inflammatory response by releasing chemical signals, such as histamine, in response to injury or infection. These chemical signals cause blood vessels to dilate and become more permeable, allowing immune cells to move into the affected tissue and fight off the infection.
