The Langer-Hans Islands are small patches found in the cells of the pancreas; they differ in form and function from the rest of the cells around them, and they were called islands because of their shape. The German student who first discovered it was Paul Langer Hans, named Blangerhans for his name. The importance of insulin secretion and glucose necessary to represent sugars, which is responsible for the regulation of sugar in the blood; If the islands uprooted Langer Hans of the body, this causes diabetes because of the lack of insulin, and when the body of insulin, it raises blood sugar. We also recall that the German explorer not only discovered these cells; he also discovered the type of skin cells and layer of skin layers that were named in his name.
Langerhans islands cells
There are two important types of cells in the Langer-Hans Islands:
- Alpha: It is the secretion of glycone, which raises blood sugar.
- Beta: It is responsible for the secretion of insulin lowering blood sugar, and maintain the balance of sugar and glucose in it.
The mechanism of action of the islands of Langer Hans is inverse, and is explained as follows: If you say the proportion of sugar glucose in the blood, these islands secrete the hormone glucokon, which supports the liver to create glucose Glucosevm blood, but if increased blood sugar and rose, it works the same way in reverse, as happened from During insulin secretion.
There are several vectors of glucose, and vary in places and functions called (Glut), and functions as follows:
- Glut 1 & 3 : Works to deliver glucose to all tissues except the liver and beta cells.
- Glut 2: It works to deliver glucose to the liver and beta cells in the pancreas.
- Glut 4 : Are the ones that control the insulin process, and are present in fatty tissue and skeletal muscles.
- Glut 5 : Works to deliver glucose to the extracellular matrix in the small intestine.
It is through this text that we have learned brief things about the mechanism of action of the pancreas, the seriousness of its loss, and its importance in the human body. In order to protect our bodies, eat healthy food and exercise, we can preserve this precious trust that God has provided us with, and we must also avoid all that harms our health, which is a crown on the heads of the healthy, whose value is known only to the weak.
