Human Body Spleen Research Paper

The origin of these organs concern people on both a medical and moral level. In a

1. Describe the anatomic location of the pancreas relative to the other organs in the upper portion of the abdominal cavity. - The pancreas is about 6 inches long and sits across the back of the abdomen, behind the stomach and liver, leveled with the top of the small intestine and it also borders the liver, spleen and kidneys. The head of the pancreas is on the right side of the abdomen and is connected to the duodenum (the first section of the small intestine) through a small tube called the pancreatic duct. The narrow end of the pancreas, called the tail, extends to the left side of the body.

The spleen, acting as a policeman, traps and destroys many of the abnormal sickle cells, resulting in rapid turnover of red blood cells and chronic anemia.

My organ is the urinary bladder for the organ paper. The function of the urinary bladder is a storage container temporarily for urine, until it is expelled through the urethra. The elasticity of the bladder is unmatched as it has the ability to increase in size to make room for increases in urine volume from 600 to 800 ml at maximum capacity. The reason for this elasticity is due to the visceral muscles and transitional epithelium located in the walls of this hollow organ, that allows this distensibility enabling it to fill and empty multiple times every day. Another function of the bladder is to aid in expelling urine from the body by contracting the detrusor muscle as well as the relaxing of the urethral sphincter; the external urethral

One of the most important organs of the lymphatic system within the body's blood filter process is the spleen. This organ does a variety of things to help keep healthy blood available to be shipped to the body for pathogen-fighting purposes. The spleen normally is about a fist size. The oval clump of blood vessels intertwined with strands of connective tissue is separated into two parts. The blood vessels that make up a large content of the spleen, are called splenic sinusoids. The organ is normally found in the left upper part of the abdomen, above the stomach, it is mostly protected by the lower ribs. This particular organ is a definite vital part in cleaning the body's blood supply. In most cases people can live without their spleen (Rettner, 2013). This of course comes with extra precautions to help fight infections but a normal life can exist. The dark purplish red mass helps to filter the blood through its many passageways of blood vessels and is soft in texture.

The spleen is an important organ located in the upper left part of the abdomen near the stomach, which has multiple functions, it produces lymphocytes, serves as a major reservoir for blood, filters blood, destroys aged blood cells, has an important function in the filtering and removing bacteria from the bloodstream, and maintains the function of our immune system.

The gall bladder is an accessory organ to the body. The gallbladder stores the bile that is made by the liver to send to the digestive tract. It is located under the liver, so they can work together in the digestive process. The structure of this organ can be described as hollow and resembles the shape of a pear when full. When the organ is empty, it can resemble more of sac. It is a very small organ, located closer to the right lobe of the liver. The gallbladder also sits closely in relation to the pancreas, located slightly off to the right-hand side of the organ. In location to the body, you can describe the organ as being within the in the upper right quadrant of the abdomen. The gallbladder’s only enzyme is the bile that is created by

Spleen is an important internal organ, an organ that is accountable for both the storage and purification of red blood cells. “The spleen serves a critical role in immune function because it purifies the blood and helps the immune system to recognize and attack foreign pathogens and allergens” (Healthline Medical Team, 2014). Spleen is located in the left side of the abdominal cavity between the stomach and diaphragm. In adulthood, the spleen is the largest lymphatic organ in the body. Blood, rather than lymph, flows through the spleen. Blood cleansed of microorganism in the spleen. The spleen store blood and destroy worn out red blood

While the spleen performs a number of important functions, it is not essential to life. Other organs such as the liver and bone marrow are able to take over many of its jobs. Your spleen may be removed (splenectomy) for various reasons. It may, for example, be removed because of an illness that affects the spleen, or if it is damaged by an injury. Also, the spleen may not work well in some diseases - for example, sickle cell disease, thalassaemia and

Spleen tyrosine kinase (SYK) is a cytoplasmic non-receptor tyrosine kinase that has been shown to be involved in intracellular signaling pathways of a number of diverse cell types. Structurally, SYK is a 72k Da protein with two SRC homology 2 domains and a kinase domain. It has a well-documented and crucial role in intracellular signaling of adaptive immune cells via immunoreceptor tyrosine-based activation motifs (ITAMs) of the classical immunoreceptors; B cell receptors, T cell receptors and Fc receptors. Activation of these receptors leads to the phosphorylation of the ITAMs’ cytoplasmic tyrosine residues resulting in the recruitment and activation of SYK. For activation, both of SYK’s SH2 domains needs to bind to the phosphorylated ITAMs of the receptor, or phosphorylation can occur at a tyrosine residue in either of the interdomains. This initial phosphorylation leads to the autophosphorylation of other tyrosine residues in the interdomains or the kinase domain, resulting in ITAM release and sustained activation.

Lymph nodes are much smaller than the spleen. The lymph nodes act as filters to cleanse lymph before it can return to the bloodstream. Each node is surrounded by a dense fibrous capsule. The spleen is the largest lymphoid organ. It functions to remove aged or no good blood, and pathogens from the bloodstream and can either store the breakdown products of RBC's or have them be processed by the function of the liver. The red pulp area contains RBC's and macrophages, whereas areas composed mostly of lymphocytes are the white pulp. The white pulp serves the immune functions of the organ. The spleen and lymph nodes are surrounded by a fibrous capsule, and has trabeculae. They both act as filters to remove unwanted products from the body. Macrophages

Human organ printers have come to save lives. This invention will creat a way for individuals and families to reconnect with generations. This printer will cure patients with diseases, sickness, and needed transplant.

Why and what the organs for the digestive system. The Pancreas: The pancreas sits below the stomach and alongside the first part of the small intestine. Its two main functions are to produce hormones and to produce pancreatic juice.

“Hereditary Spherocytosis is a condition that is passed down from parent to child and it affects the red blood cells and the spleen” (Genetics Home Reference). The job of the spleen in a healthy human body is to clean the blood of bacteria. Spherocytosis causes the red blood cells to change shape, therefore making it difficult to move through the spleen (Wint). “When a person has HS, the red blood cells have a fragile membrane. At first, the red blood cells have a normal shape. However over time little pieces of their membranes are removed when the cells pass through the spleen. The shape becomes rounder like a sphere” (Seattle Children's hospital research foundation).

The enlargement of the spleen is know as splenomegaly(Splenomegaly). The spleen has active roles in different things. These roles being, immunosurveillance and hematopoiesis(Splenomegaly). The spleen lies within the left upper quadrant of the peritoneal cavity and touches the stomach, the left kidney, the splenic flexure of the transverse colon, and the tail of the pancreas(Splenomegaly). Normally the spleen cannot be palpated, although those with a small build can palate his or her spleen(Splenomegaly). The spleen has four main functions. The first one being eliminating microorganism and particulate antigens from the bloodstream, second being the synthesis of immunoglobulin G properdin and tuftsin, third being the removal of abnormal red blood
