Liver tissue is collection of thousands of such lobules. These lobules are made up of hepatic cells which are the basic metabolic cells of the liver (MamasHealth.com, 2000). The liver is a complex organ. It performs over 500 different functions. Some of the functions include: to produce substances that break down fats, convert glucose to glycogen, produce urea which is the main substance of urine, make certain amino acids which are the building blocks of proteins, filter harmful substances from the blood such as alcohol, storage of vitamins and minerals (vitamins A, D, K and B12) and maintain a proper level or glucose in the blood. The liver is also responsible for producing cholesterol and it is estimated that it produces about 80% of the cholesterol in the body (MamasHealth.com, 2000). Among these functions the two of most important functions is to control of amino acid concentration and detoxification. Urea is produced in the liver and is a metabolite of amino acids. Ammonium ions are produced due to the breakdown of amino acids. And these ammonium ions are used in the biosynthesis of nitrogen compounds and excess ammonium ions are converted to urea (Royal Society of Chemistry, N.D.). The liver's basic functions are three fold: Vascular, Secretory and Metabolic. In other words it plays an important role in the major systems of the body, particularly in the digestive, circulatory and endocrine systems of the human body. In simple terms the vascular function includes being a major blood reservoir, filtering over a liter of blood every minute. The liver effectively removes bacteria, endotoxins, antibody complexes and various other particles from the circulation. The liver is one of the most vital organs in the body when it comes to detoxifying or getting rid of toxins. The liver plays a key role in most metabolic processes, particularly detoxification. The liver neutralizes a broad range of toxic chemicals, both those produced inside the body and those coming from the external environment. In human system the normal metabolic processes produce a wide range of chemicals and hormones and it is worth mentioning that the liver has evolved as an efficient neutralizing mechanisms. If it was not for the liver, then our bodies would have been full of toxics and would have become very difficult for the survival. There is tremendous change in the environment in recent years and it is continuously pumped with toxic chemicals every day. Human beings are as a result exposed to these chemicals. The food we eat is contaminated with pesticides, the air we breathe contains several poisonous gases, and the water we drink has chemicals. In other words many of the toxic chemicals come from the environment: the content of the bowels and the food, water, and air. The harmful polycyclic hydrocarbons such as DDT, dioxin, 2,3-D, PCB, 2,4,5-T and PCP are the basic components of various herbicides and pesticides. And these are example of chemicals that are now found in almost all fat tissues measured. Even those eating unprocessed organic foods need an effective detoxification system because all foods contain naturally occurring toxic constituents. Hence in all these cases liver plays the most important role of detoxification. The liver plays these vital roles in detoxification through the following processes: it filters the blood to remove large toxins, synthesizes

Industry review of retirement home industry Research Paper

Industry review of retirement home industry - Research Paper Example enture should aim at making profits to the investor, but it must also aim at the provision of quality services to the people in the immediate community (Scaffa and Reitz, 2014). There are two types of retirement industries available to individuals who have attained the age of retirement including the independent and the dependent communities.

On the other hand, the dependent industry is bestowed with the responsibility of the provision of housing arrangements alongside other health care services. These constantly change with the change in the needs and the tastes of the community (Hillstrom and Hillstrom, 2002). In the retirement industry market, the communities are expected to increase especially in America to over 77 million in the next two years. The retirement group is expected to be shopping for the best option in the market regarding housing and health services in the next 2 decades. The venture into the retirement industry requires some capital to help run the facility in one way or the other. Therefore, this industry seems to be centered onto the senior citizens with some sizeable retirement incomes that are adequate to handle the expenses. For instance, in America, the most expensive retirement scheme requires a capital of between $ 100, 000 to $ 1 million (Scaffa & Reitz, 2014). There has been an escalating trend in the development and the expansion of the retirement industry in the American economy. However, in 2007, there was a recession in the US that spread up to the year 2013. This recession slowed down the growth in the retirement industry. This forced several individuals to delay the retirement due to the dwindling personal assets. There
