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.
Answer:
Otitis media is generally caused by dysfunction of the Eustachian tube, which can be due to Pharyngitis.
Explanation:
The otitis media is an infection or inflammation of the middle ear and is mostly caused by the inflammation of the mucous membranes in the nasopharynx leading to dysfunction of the Eustachian tube. This can be caused due to a upper respiratory tract viral infection or streptococcal pharyngitis (strep throat) or due to some allergy.
Pharyngitis or sore throat is a type of inflammation caused by upper respiratory tract viral infection.
Therefore, Otitis media can be caused by Pharyngitis and thus it is associated with it.
