13. Which of the following describes a neutrophil? 1. abundant, agranular especially effective against cancer cells 2. abundant, granular especially effective against bacteria 3. rare, agranular releases antimicrobia I defensins 4. rare, granular contains multiple granules packed with histamine

## Step 1<br />Neutrophils are a type of white blood cell, which are part of the immune system. They are known for their ability to quickly respond to and eliminate bacteria, making them a crucial component of the body's defense against bacterial infections.<br /><br />## Step 2<br />Neutrophils are characterized by their granular nature, which means they contain granules filled with enzymes that can break down bacteria. This makes them particularly effective against bacterial infections.<br /><br />## Step 3<br />Neutrophils are also abundant in the body, which means they are not rare. This is in contrast to some other types of white blood cells, such as eosinophils or basophils, which are less common.<br /><br />## Step 4<br />Given these characteristics, the description that best fits neutrophils is that they are abundant, granular, and especially effective against bacteria.
