WEBThe immune system builds many lines of defense. The cells of the innate immune system provide an early response to danger. They move through the body looking for signs of damage or infection of other cells. Then they destroy those cells. Another major defense is called the adaptive immune system.

WEBApr 10, 2024 — The Third line of defense: The third line of defense encompasses the Acquired response, which is highly specific and adaptive. It involves the activation of B and T cells, which are responsible for producing antibodies and orchestrating a targeted immune response against specific pathogens.

WEBJul 7, 2024 — There are three lines of defense: the first is to keep invaders out (through skin, mucus membranes, etc), the second line of defense consists of non-specific ways to defend against pathogens that have broken through the first line of defense (such as with inflammatory response and fever).
In brief: The innate and adaptive immune systems
WEBAug 14, 2023 — Antibodies have three main functions: They make germs harmless – for example, by directly attaching to the cell surface of viruses or bacteria, or by binding harmful substances made by these germs. This prevents the germs from latching onto normal body cells and infecting them.

The Immune Response - Let's Talk Science
WEBJul 23, 2019 — Your immune system has three levels of defence. If a pathogen passes through one level, the next level takes over. The first line of defence is your innate immune system. Level one of this system consists of physical barriers like your skin and the mucosal lining in your respiratory tract.
