Who knew anything in our class about the lymphatic system before starting anatomy and physiology? Our body does amazing things, and the lymphatic system indeed takes part in the amazing. Each and every day our body has to fight off pathogens which are disease producing microbes like bacteria and viruses. We also get cuts, bumps, scratches, burns, and many other things our body protects us against. There is two types of resistances that our body fights against which is nonspecific and specific. The system of our very body that is responsible for specific resistance is the lymphatic system!!! It also does fight off some aspects of nonspecific resistance.
Our Lymphatic system has three primary fuctions:
1) Draining excess interstital fluid. Lymphatic vessels drain excess interstitial fluid from tissue spaces and return it to the blood.
2) Transporting dietary lipids. Lymphatic vessels transport lipids and lipid-soluble vitamins (A, D, E, and K) absorbed by the gastrointestinal tract to the blood.
3) Carrying out immune responses. Lymphatic tissue initiates highly specific responses directed against particular microbes or abnormal cells.
Any pathogen that we have come across in our time is remembered due to our great lymphatic system and some special cells. We defend ourself against specific invading pathogens and foreign tissues each day and its called specific resistance or immunity. The cells and tissues that carry out immune responses can by physiologically considered a system so they are called the immune system. Immunity consists of two kinds of close responses called cell-mediated immune responses, and antibody-mediated immune responses. Cell- mediated immune responses are directed against intracellular pathogens, some cancer cells, and tissue transplants. Antibody-mediated immune responses are directed against extracelluar pathogens. They both lead to phagocytosis which then finishes the work =)
The lymphatic system is very important in our lives. Each day we do our everyday activities only because our special systems of our body protects us, lymphatic being one of the most important. Not being able to fight off pathogens would kill us in minutes due to the factor of rapid cell reproduction of pathogens.

ReplyDeleteThe nutrients we feed our body from fresh foods are the potential energy, and then when changed into chemical energy with oxygen through the oxidative process there is life in the cells. Eating junk food forces us to use up more of its oxygen reserves than usual in order to metabolize the preservatives and what few nutrients may actually be in the food.
Dense food compounds, such as fats and proteins, are not only low in oxygen content, but also require extra oxygen from our bodies to convert them into energy which further depletes our oxygen reserves. Other oxygen-robbing foods include processed sugar, white flour, alcohol, coffee and soda drinks.
