Now, earlier we mentioned in a previous lecture, we basically mentioned that our liver can also act as an endocrine gland. It can produce a special type of enzyme, special type of protein that acts as a hormone. So basically, liver produces thrombopolietin, which is a glycoprotein hormone that is responsible for controlling the blood clotting cascade, as we'll see in a future lecture. It is responsible for producing platelets that are involved in the blood clotting process. Now, finally, it acts as an exocrine gland. It produces the special type of bile substance that we spoke of earlier that is needed to actually multiply and break down our fats inside the small intestine.
