Verified step by step guidance

Understand the role of each cell type mentioned in the problem: Neutrophils, Erythrocytes, B lymphocytes, and T lymphocytes.

Neutrophils are a type of white blood cell that primarily function in the innate immune response by engulfing and destroying pathogens.

Erythrocytes, or red blood cells, are responsible for carrying oxygen from the lungs to the rest of the body and do not play a direct role in the immune response.

B lymphocytes are involved in the adaptive immune response by producing antibodies that target specific antigens.

T lymphocytes are crucial for orchestrating the immune system response. They help regulate the activities of other immune cells and can directly attack infected cells. Therefore, T lymphocytes are the cells that orchestrate the immune system response.
