About glands...
Adrenal Glands:
Thymus Gland:
We cannot stress the importance enough about the thymus gland and the immune system . It "instructs" certain T-cells what to attack and when. Some of the T-cells, in turn control other white cells, responsible for maintaining certain antibodies. Without the thymus' s instructions, the T-cells may fail to attack enemies like bacterias, viruses, and cancer cells.
or, they may even mistake some of your own cells and may mistake your enemy and attack you, known as autoimmune disease..
Examples of autoimmune disease are, multiplesclerosis, cancer, atherosclerosis, adult-onset diabetes, and rheumatic diseases such as arthritis.
Pancreas:
Clusters of cells which flow into this duct and later into the duodenum for digestion of proteins, fats, and carbohydrates. If the ducts leading from the pancreas are blocked in some way, the digestive fluids build up in the pancreas and may then become activated so that they digest the pancreas itself! This condition is known as acute pancreatitis. Pancreatic cancer has the worst prognosis of all the types of cancer. This is probably because of the spongy, vascular nature of this organ and its vital endocrine and exocrine functions.
