One of the great struggles in modern medicine is being able to replace vital organs in patients that are unable to be donated, such as the lower intestines and stomach. There are many obstacles that stand in the way between being able to synthesize or re-create said organs, but simple builds and simple ideas can help scientists to try to overcome the obstacles. Re-creating the human stomach in an artificial setting will help understand the basics in artificial organ replacement.
The first step in creating an artificial stomach is background research. This Research Project will take extensive research to complete. An inexpensive (.99c) program was purchased early into the research project that highlights the digestive system and how it all “fits together.” The application also gives a very good and detailed external view of the stomach and it's connection with the Esophagus.
The second step is the build of schematic 1. This is the first build and will eventually be tested to see if it can meet the following criteria: The build must be able to withstand the acidic conditions and also must be able to break down food to be moved into the lower intestines.
Once the schematic is complete, build one will begin and then tested. After testing has concluded, edits in the schematic will be made and the process will repeat. A “Reflection” Period will begin when a suitable (fits all the criteria) is completed. This reflection period is the stage when conclusions on the builds are made, and where the overall project is reflected upon. What could be improved? How realistic is it?
The materials required for the creation of an artificial human stomach include: Drafting materials that include draft paper and SolidWorks, a ...

Brendan Maher, in his article “How to Build a Heart” discusses doctor’s and engineer’s research and experimentation into the field of regenerative medicine. Maher talks about several different researchers in this fields. One is Doris Taylor, the director of regenerative medicine at the Texas Heart Institute in Houston. Her job includes harvesting organs such as hearts and lungs and re-engineering them starting with the cells. She attempts to bring the back to life in order to be used for people who are on transplant waiting lists. She hopes to be able to make the number of people waiting for transplants diminish with her research but it is a very difficult process. Maher says that researchers have had some successes when it comes to rebuilding organs but only with simples ones such as a bladder. A heart is much more complicated and requires many more cells to do all the functions it needs to. New organs have to be able to do several things in order for them to be used in humans that are still alive. They need to be sterile, able to grow, able to repair themselves, and work. Taylor has led some of the first successful experiments to build rat hearts and is hopeful of a good outcome with tissue rebuilding and engineering. Scientists have been able to make beating heart cells in a petri dish but the main issue now is developing a scaffold for these cells so that they can form in three dimension. Harold Ott, a surgeon from Massachusetts General Hospital and studied under Taylor, has a method that he developed while training. Detergent is pumped into a glass chamber where a heart is suspended and this detergent strips away everything except a layer of collagen, laminins, and other proteins. The hard part according to Ott is making s...

The topic of this paper is acid deposition, also known as acid Rain. Acid rain is precipitation, as rain, snow or sleet containing relatively high concentration of acid forming chemicals. As the pollutants from coal, smoke, chemical manufacturing, and smelting, that have been released into the atmosphere and combine with water vapor, the harmful deposition is created (http://dictionary.reference.com/browse/acid+rain). Acid rain affects many things greatly.
...ve eaten, to break down the food into a liquid mixture and to slowly empty that liquid mixture into the small intestine. Once the bolus has entered your stomach it begins to be broken down with the help of the strong muscles and gastric juices which are located in the walls of your stomach. The gastric juices are made up of hydrochloric acid, water, and mucus- and the main enzyme inside of your stomach is what is known as pepsin, which needs to be surrounded in an acidic setting in order to do its job, that is to break down protein. Once the bolus has been inside of your stomach for long enough it begins to form into a liquid called chyme, and what keeps the chyme from flowing back into our esophagus are ring shaped muscles known as sphincters located at the beginnings and ends of the stomach and they have the task of controlling the flow of solids and liquids.
In Chemistry 221, we are learning how to name acids. In this lab we used hydrochloric acid (HCl), the reason I knew it was called “hydrochloric” was due to the rules of naming acids. When there is no oxygen involved, the “hydro” prefix is put in front, followed by the root of the second element (which happened to be chlorine) and then add the suffix –ic at the end.
The process of hydrofracking allows for a new source of renewable energy, but it takes a toll on the environment. Five-hundred plus of toxic chemicals like hydrochloric acid, sodium chloride and formic acid are left in the ground. The chemicals produce gases, there...
The digestive system is interesting, complex and truly important to our daily lives. Without the digestive system energy and nutrients vital to the body could never reach body cells and a person wouldn't be able to do all the things they like to do, such as study, play sports, and hang out with friends. The body uses various organs and chemicals to break down food. The breakdown of food he... ...
The cilia found in epithelial cells means that substances can pass easier and quicker. Squamous epithelial tissue is very thin and also very flat. It is usually one cell thick and is therefore in contact with the basement membrane. Because it is so thin, it is brilliant at diffusion and filtration, and it is also found in locations where these functions are essential. Squamous epithelial cells also have an egg-shaped nucleus. Columnar epithelial tissues are elongated and column-shaped. They occur in one or more layers. This type of epithelial tissue enables movement of molecules due to the simple thin structure and therefore allows easy exchange. The nucleus is also elongated and are normally located near the base of the cells. Columnar epithelium makes up the lining of the stomach and also the lining of the intestines. Some of which are specialised for sensory reception, for example the nose, ears and taste buds. Unicellular glands are found between the columnar epithelium and the duodenum. They secrete mucus, lubricating the surface of cells. Cuboidal epithelium tissues are a cuboidal shape, and each have a circular nucleus in the middle of them. This type of epithelium tissue is found in the

A number of organs have the intrinsic ability to regenerate, a distinctive feature that varies among organisms. Organ regeneration is a process not fully yet understood however when its underlyning mechanism are unreveled, it holds tremendous therapeutic potential for humans. [28]

This report provides an insight into the differences in the structure of cells and the way that they carry out their internal mechanisms. Cells form the basis of all living things and they are the smallest single unit of life. Cell biology is the study of cells and how they function, from the subcellular processes which keep them functioning, to the
