the body's defence system against diseases and infections Humans as organisms
The part of the body that provides a natural defense against invading foreign agents such as bacteria and viruses.
The immune system is the body's defence system, which helps protect it from disease, bacteria and viruses.
The body's defense mechanism against any injury or invasion by a foreign substance or organism.
A complex system that normally protects the body from infections. The immune system consists of a group of cells, the chemicals that control those cells, and the chemicals that those cells release.
A complex that protects the body from disease organisms and other foreign bodies. The system includes the humoral immune response and the cell-mediated response. The immune system also protects the body from invasion by making local barriers and inflammation.
Intricate mix of cellular, molecular, and antibody components (proteins) that protects the body against foreign invaders.
A biological defence system that has evolved in vertebrates to protect them against the introduction of foreign material (such as pollen, or invading micro-organisms) and to prevent the body from developing cancer. Source : PhRMA Genomics
The immune system is a set of mechanisms that protect an organism from infection by identifying and killing pathogens. This task is extremely difficult, since pathogens range from viruses to parasitic worms and these diverse threats must be detected with absolute specificity amongst normal cells and tissues. Pathogens are also constantly evolving new ways to avoid detection by the immune system and successfully infect their hosts.
