The Immune System in All Mammals Works
The immune system in all mammals works through almost every system of the body, from the surface of the skin right into the marrow of the bones.
A wide range of parts of the body contain cells that are integral to a healthy and efficient immune system that defends the body from both internal dangers, such as cancer cells, and external pathogens, such as viruses and bacteria.
Cat’s may respond to attack from infection in various ways. For example, brain may set its thermostat at a higher level to induce a fever.
Not eating is another defensive strategy.; During an infection, a cat releases leucocyte endogenous mediator (LEM).
This inhibits the absorption of iron, which is vital for the multiplication of some bacteria, from the gut.
