Human Pathology Research Paper

Human Pathology is the study of the origin, nature, and course of diseases. There are around 78 organs in the body that all have their own functions. Organs are collections of millions of cells that are grouped together to perform various tasks in the human body. With that being said there are many conditions, disorders, and diseases that can affect these organs. I researched the following systems: Lymphatic, Endorcine, Digestive, and Respiratory which all contain important organs (Merriam-Webster dictionary). The Endocrine system is a collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood. It contains the following organs: pituitary

This system transports fluid (lymph) containing infection-fighting white blood cells throughout the body. Organs that can be found in this system are as follows: tonsils, adenoids, spleen, thymus, and lymph nodes. Each of these organs have a special task in the system. Tonsils are the first line of defense. The spleen is the largest lymphatic organ that stores white blood cells and platelets and recycles red blood cells. It also helps fight different forms of bacteria that call pnemonia and meningitis. The thymus is where T-cells mature. The lymph nodes produce and store cells that fight against infections and diseases. There are hundreds of lymph nodes found in the body. You can find them located in the lungs and heart or you can find them under the arm or in the groin. One of the most common conditions in this system is call lymphadenopathy which is the enlargement of lymph nodes. Swelling occurs due to lymph node blockage and cancers. Infections that cause this condition include bacterial infections such as strep throat. Lymphoma is a cancer in the lymph nodes that occurs when lymphocytes grow rapidly and uncontrollably. Castleman disease is a group of inflammatory disrders that also cause inflammation and can result in multiple organ dysfunction. Another condition is Lymphangiomaosis which is a disease that involves multiple cysts or lesions form from lymphatic vessels
