The bladder is a hollow organ in the human body that stores urine. Urine is made in the kidneys and travels down to the bladder through tubes called ureters. The normal capacity of the bladder is around 400mL to 600mL (WebMD). The bladder is made of muscles that expand to accommodate urine and contract to release it. The bladder is a very significant organ for survival. Without a bladder the human body would have no way of releasing the toxins that it encounters on a daily basis. Urination is the body’s response of releasing the toxins and detritus that it takes in on a daily basis. For any reason if the flow of urination is disrupted it can cause serious health problems for the individual. This is where the artificial bladder comes into play. If someone’s kidneys are failing an artificial bladder may be there only option. Before the method discovered by Dr. Anthony Atala, artificial bladders were made from a small part of the own patients intestines. This worked but soon the problems arose again. Thanks to Dr. Atala, a biodegradable mold shaped like a bladder is seeded with cells (from the patient) and dipped in a growth solution (Atala). The research and process has been in use for over a decade and the patients have had no further complications with their bladders. It has been over a decade since the first artificial bladder transplant of this kind took place. Thus solving many cases of kidney failure and benefitting those with weak and damaged bladder. “An artificial bladder should provide adequate urine storage, allow volitional complete evacuation of urine and preserve renal function,” (Desgrandchamps). The entire world population is impacted by this discovery. The developments can help solve majority of th...

At first fetal tissue stem cell research was "conducted without and scrutiny from the public sector" but after Roe vs Wade things got a little more heated. In 1928 Italian researchers performed the first ever, documented, "procedure" with fetal tissue where doctor took the pancreas of a fetus and "put it in" a patient with diabetes to see if the patients condition would improve how...
Skloot gains credibility by describing researchers who took different approaches to culturing cells. A French surgeon at the Rockefeller Institute named Alexis Carrel grew his “immortal chicken heart.” Many researchers believed it was not possible to have tissues living outside of the body, and Carrel proved them wrong by growing a sliver of chicken-heart tissue in culture successfully. Doctor George Gey was the head of tissue culture research at Johns Hopkins Hospital where Henrietta was treated for her cancer. Dr. Gey, along with his wife, had spent years trying to grow cells outside of the human body in search of the cause and cure for cancer. Most cells they tested either died or hardly grew. In The Immortal Life of Henrietta Lacks, Skloot writes, “The Geys were determined to grow the first immortal human cells: a continuously dividing line of cells all descended from one original sample, cells that would constantly replenish themselves and never die” (30; ch. 3). Little did they know, they were about to grow the first immortal human cells, using cells they removed fro...
In 2001 scientist attempted to create a cloned human embryo, they had consulted all the necessary sources before getting the “ok” to begin “creating”. Then they had to find a female subject to donate eggs. To start the process of cloning they need to use a very fine needle and get the genetic information from a mature egg. Then they inject it into the nucleus of a donor cell. The female donors were asked to take psychological and physical tests to screen for diseases and what not.
2013). Inappropriate use of urinary catheter in patients as stated by the CDC includes patients with incontinence, obtaining urine for culture, or other diagnostic tests when the patient can voluntarily void, and prolonged use after surgery without proper indications. Strategies used focused on initiating restrictions on catheter placement. Development of protocols that restrict catheter placement can serve as a constant reminder for providers about the correct use of catheters and provide alternatives to indwelling catheter use (Meddings et al. 2013). Alternatives to indwelling catheter includes condom catheter, or intermittent straight catheterization. One of the protocols used in this study are urinary retention protocols. This protocol integrates the use of a portable bladder ultrasound to verify urinary retention prior to catheterization. In addition, it recommends using intermittent catheterization to solve temporary issues rather than using indwelling catheters. Indwelling catheters are usually in for a longer period. As a result of that, patients are more at risk of developing infections. Use of portable bladder ultrasound will help to prevent unnecessary use of indwelling catheters; therefore, preventing

Fresh fruits and vegetables can also help the bladder and urinary tract because it is loaded with essential nutrients.
Dialysis tubing is made from regenerated cellulose or cellophane, and is used in clinical circumstances to ensure that molecule have a filtered flow, and that larger solute molecules do not enter the dialysis tubing (Alberts, 2002). Like a cell membrane, dialysis tubing has a semi-permeable membrane, which allows small molecule to permeate through the membrane. Thus, the dialysis tubing mimics the diffusion and osmosis processes of the cell membrane (Alberts, 2002). Although the dialysis tubing has a semi-permeable membrane, which mimics a cell, its structure is different. The me...
In the human body, there are a number of systems that have their own importance and provide different functions to help keep us alive. One of these systems is the urinary system, also known as the renal system. As blood courses through the body, waste products are transferred into the bloodstream that needs to be extracted. The urinary system is designed to help the body remain free of excess water and waste that we no longer need. This particular system is made up of two kidneys, two ureters, a urinary bladder and a urethra that produces, stores, and then excretes urine out of the body. When it comes to the urinary system,
Incontinence pads are specifically designed to absorb urine leakage and protect the skin from wetness. Research has shown that three out of every five of its consumer members used some type of incontinence pad or adult nappy.

In 2004 another experiment was created in Rochester Minnesota at the Mayo Clinic. The clinic was the first to create pigs that used human blood in place of their own. In 2005, two more hybrids are created the first being a mouse with human brain cells and the second is a feline-human protein hybrid. These hybrids are being created to fight and cure cancers and diseases including Parkinson and Alzheimer’s disease. 2007 and 2008, sheep ...
