A client with a right leg fracture is returning to the orthopedist to have the cast removed. During cast removal, it is important for the nurse to assure the client that he or she won't be cut.
<h3>What is cast for?</h3>
Cast is composed of a bandage that, when wet, can be molded and, when dry, becomes resistant. It serves to maintain the position of the injured place until everything is well again.
The position maintained by the cast is that of rest or reduction, in the case of fractures, so that the fractured bone does not move.
The cast immobilizes one joint above and one below the area to be treated.

Answer:
Kupffer cells, also known as stellate macrophages due to their particular structure while viewed under a microscope, were first identified by scientist Karl Wilhelm von Kupffer, after whom the cells were named, in 1876.
These cells, whose origin is in the yolk sack during fetal development, later on move to the liver where they will stay and further differentiate into their mature versions.
These cells are part of the liver cells, and are found particularly on the walls of the sinusoids, where they perform their two most important tasks. First, these cells are part of the immune system, as they are essentially macrophages. However, their role is pretty unique, as they are responsible not just for phagocytosis of invading bacteria, and other pathogens, and initiating immune responses, but also, this cell plays a role in decomposing red blood cells who are dying, and taking up the hemoglobin from them to further break that into reusable globin, and the heme group, from which iron is further extracted to be re-used and also to create bilirrubin, a part of bile.
Finally, these cells have been found to be connected to hepatic cirrhosis, as in their process of detoxifying ethanol, they produce toxins that force the liver cells to produce collagen, and thus to become fibrous.
