A Busy Protein
Blood is made up of many components. Red blood cells carry oxygen to all parts of the body. And even though hemoglobin is based on iron, the healthy body, protected by rust inhibitors, doesn't rust. White cells and other blood components fight infection. It's difficult to decide which of the components of blood are more amazing in their design.
But if awards were given to the various components of blood for the amazing ways in which they work, serum albumin would certainly be in the running. Like one of those gadgets advertised on cable television, serum albumin seems to do more things in the bloodstream than seems possible.
Serum albumin, which is made by the liver, regulates the volume of your blood, helping to keep your blood pressure healthy. It also controls your blood chemistry so that all the components are there in the right concentration. It stores molecules and moves them to where they are needed when they are needed. When you take an aspirin or a drug, serum albumin sees to it that the medicine gets to where it is needed. Serum albumin also prevents an enzyme which digests proteins in your digestive tract from digesting the proteins in the rest of your body.
Indeed, as the Bible says, much of our physical life happens in our blood. But eternal life is only found in the blood of Jesus Christ, shed on the cross in our place – His death in our place – for the forgiveness of our sins before our Creator.
