👉 Reserves refer to the body's natural defenses, primarily composed of immune cells and proteins, that are maintained in various tissues and fluids to combat infections. When an infection occurs, these reserves activate to recognize and neutralize pathogens such as bacteria, viruses, fungi, and parasites. Key components include white blood cells (like neutrophils, macrophages, and lymphocytes), antibodies, cytokines, and complement proteins. These elements work together to identify, engulf, and destroy invading microorganisms, as well as to modulate the immune response to prevent excessive damage to host tissues. The effectiveness of these reserves is crucial for a rapid and robust defense against infections, helping to limit their spread and severity.
