THE IMMUNE SYSTEM AND ITS CONTRIBUTION TO THE MAINTENANCE OF HOMEOSTASIS

The body of a human being needs to have a defense mechanism of which it can be able to defend itself from foreign pathogens (germs and microorganisms . The composition of this system is made up of proteins tissues and organs which have all been derived from the basic unit of the body i .e . the cell . The complexity of this system

is able to relay information throughout the many different kinds of antigens that are able to block incoming agents or they are self antigens . Hence an imbalance of the immune means that one has been succumbed to an infection or an infection is thus setting in

Research is also showing that we are all protected by the immune system which is able to shun the actions of unwanted antigens which have invaded our body system . But the advantage to the body is that there are defense barriers in every entry site to the host . Also the immune travels the body through the membrane cofactor protein and the decay accelerating factor which is killing all that is not needed but then they also attack the healthy cells too in this check . Therefore , the healthy cells rely on protective protein cover so as to avoid being hit (USA Today , 02 /1993 ,

Therefore , at any time the immune system needs to be is functioning best , the body functions need to be at an optimum level which is referred to us as homeostasis . This is therefore the steady state that the body needs to be in so as to be functioning well

The body is marvelously organized in that the grouping of cells brings about the tissue cell , tissues bring about the organs (which cannot be able to work on their own , and the organs therefore compose to bring about the system . The system therefore , gives the various activities such as

Filtration by the excretory system

Body support and protection of the internal organs is aided by the skeletal system

Distribution of nutrients by the aide of the circulatory system

Breathing in and out of air by the respiratory system etc

The body can be able to interact with the external environment despite the size , weight and the metabolism rate of any given organism . The internal environment of the animal is kept at a regulated level despite the external environment ' interactions may vary in relation to the internal environment the regulation is through the homeostatic mechanism that relies on negative feedback . The negative feed back needs a receptor , a control center and an effector . When a receptor detects for instance a change in temperature the control center receives information about the change from the receptor and then relays an appropriate response by the effector (Campbell , Reece Mitchell , 1999
