Immune system and how it works
Wanted to share this with Apsense Community.
The lymphatic system is a network of vessels which returns fluid from spaces between
cells to the blood circulation.
Lymph nodes, the spleen and the thymus gland are part of the lymph system, and they produce lymphocytes cells which identify then set out to destroy and eliminate foreign substances, microbess and cancer cells.
There are two types of lymphocytes: B-cells, and T-cells. T-cells, which are produced in the thymus, can destroy foreign bodies directly, whereas B-cells, produced in the spleen will secrete antibodies against these undesirables in order to eliminate them. Similar to lymphocytes are neutral killer cells (NK) which are particularly lethal agaisnt cancer cells, destroying them outright.
The white blood cells found in the bloodstream, phaocytes and lymphocytes play an important role in immunity by destroying invading bacteria and removing dead and damaged tissue. An optimally functioning immune system is in perfect balance. So although it is primed to destroy foreign substances, it allows entry to those that we need, such as food.
For example, the gut's immune ecology contains a balance of both friendly and unfriendly bacteria. As long as the two stay in harmony, digestive immunity is strong. But if unfriendly bacteria start to proliferate perhaps because your diet is high in sugar and saturated fat, you can develop digestive complaints and fungal infections.

Doing a lot of research on the various systems within the body. Being a personal trainer you should know the inside of the body, as well as the outside.
