Which system in the body helps heal and fight infections?

The lymphatic system is integral to healing and fighting infections because it plays a crucial role in the immune response. This system consists of a network of lymph nodes, lymph vessels, and lymph, which collectively transport lymph fluid throughout the body. Lymph contains white blood cells, particularly lymphocytes, which are essential for the immune response.

When the body is exposed to pathogens, the lymphatic system mobilizes these immune cells to the site of infection, enabling them to identify and eliminate harmful microorganisms. Additionally, the lymphatic system helps in the removal of waste products, dead cells, and toxins from tissues, further contributing to the healing process. Thus, the lymphatic system is vital for protecting the body against infections and supporting recovery after injuries or illnesses.
