Verified step by step guidance1
Step 1: Understand the role of the immune system in fighting infections. The immune system is composed of various cells that work together to identify and eliminate pathogens such as bacteria, viruses, and other harmful organisms.
Step 2: Learn about the different types of immune cells mentioned in the problem: Neutrophils, T lymphocytes (T cells), B lymphocytes (B cells), and Macrophages. Each has a specific function in the immune response.
Step 3: Focus on B lymphocytes (B cells). These cells are specialized white blood cells that produce antibodies. Antibodies are proteins that bind to specific antigens on pathogens, marking them for destruction or neutralizing their harmful effects.
Step 4: Compare the roles of the other cells: Neutrophils are primarily involved in phagocytosis (engulfing and digesting pathogens), T lymphocytes (T cells) are responsible for cell-mediated immunity and activating other immune cells, and Macrophages are also involved in phagocytosis and antigen presentation to T cells.
Step 5: Conclude that B lymphocytes (B cells) are the primary cells responsible for producing antibodies, which are crucial for the humoral immune response to fight infections.
