Which type of white blood cells contains enzymes to help digest and kill bacteria and parasites?

Leukocytes, commonly known as white blood cells, play a crucial role in the immune system, particularly in defending the body against infections and foreign invaders such as bacteria and parasites. Within the category of leukocytes, there are several different types, each with specialized functions.

The specific white blood cells that contain enzymes to help digest and kill bacteria and parasites are primarily neutrophils and eosinophils, both of which fall under the broader classification of leukocytes. Neutrophils are the most abundant type of white blood cell and are usually the first responders to sites of infection. They contain granules filled with enzymes and antimicrobial substances that can destroy pathogens. Eosinophils target larger parasites and are also involved in allergic responses, containing enzymes that help combat such threats.

In contrast, erythrocytes are red blood cells responsible for transporting oxygen throughout the body, and platelets are cell fragments involved in blood clotting. Monocytes are another type of leukocyte that can differentiate into macrophages and dendritic cells, playing roles in phagocytizing pathogens and presenting antigens, but they do not directly contain the same enzyme-rich granules that are primarily utilized by neutrophils and eosinophils.

Hence, the designation of
