A few Medical Facts and God

Beta Cells, are a type of cell in the pancreas in areas called the islets of Langerhans. They make up 65-80% of the cells in the islets.
Function
Beta cells make and release insulin, a hormone that controls the level of glucose in the blood.
Sulfonylurea derivatives are a class of antidiabetic drugs that are used in the management of diabetes mellitus type 2 ("adult-onset"). They act by increasing insulin release from the beta cells in the pancreas.
For this antidiabetic drug to work it needs a receptor in our bodies, now in the beta cells there is a receptor called Sulfonylurea receptor or SUR1 which allows the antiadiabetic drug to work.
The question is why would our beta cells have these receptors if the body does not produce this substance/drug?
I wonder how is it possible that there are doctors who still don't believe in God. This is just one fact out of umpteenhundredths awesome facts about the wonderful creation of God that is the human body.

I found out today and I was just amazed, God is so incredible!! He never ceases to amaze me!

May your day be blessed richly with God's presence!!
