Deyanira Rondon Biology Unit 4 Assignment Cells of the Spleen Professor: Jeffrey Parker 31 Jan 2015 In order for our organs to work properly and perform their specific function their cells must be differentiated. Due to that, our body is able to maintain homeostasis. Each and every cell in our body has a specific job/task that if performed incorrectly can lead to diseases or a debilitating. Inside your tissue, cells are constantly renewing themselves through the process of division, although they are doing this at different rates depending on cell type. The spleen is positioned in the upper abdomen, and is the largest lymphatic organ in the body. The spleen’s role in the immune system is quite important because not only does it purify the blood it also helps the immune system with fighting off infection. The spleen is comprised of cells that are specific to maintaining a “healthy” state. Cells like B and T lymphocytes make up the spleen as well as macrophages. The spleen also stores red blood cells within the organ for times in which the body experiences trauma which could be ranging from a cut to severe hemorrhaging. Although one can live without the spleen a spleen rupture is life threatening because he/she could then bleed out. The cells that make up the spleen allow the organ to perform the functions specific to those cells. For example if the spleen had cells similar to those in the heart that allow it to contract it would no longer serves its purpose as an immunity defense organ and a blood reservoir in actually the spleen can hold almost a cup of blood. White blood cells like macrophages in the spleen aid in consuming or eating old red blood cells. Although the spleen provides the human body with immunity and other vitally important functions without it you can survive and your body will then adapt. Having an organ which has more than one function is an
