Liver Cirrhosis - Research Paper Example The Liver Weighing about 1.4 kg, i.e. about 3 lb in adults, the liver is the heaviest organ of the human body. It is also the second largest organ, skin being the first. It is located below the rib cage at the right hand side of the body. To be precise, it occupies part of the epigastric regions in the abdomino-pelvic cavity and part of the hypochondriac region (Tortora and Derrickson, 2008, p. 945). A healthy liver is an extremely important asset for an individual’s health and well-being. As Chopra (2001) writes, the liver is â€Å"akin to a master conductor who is orchestrating a number of essential functions†, working as a â€Å"central manufacturing factory†, a processing plant for toxic waste and even as a warehouse, all at the same time (p. 4). Anatomy of the Liver The liver has two irregularly sized lobes – the larger right lobe, and the smaller left lobe. The two lobes are separated by a fold of mesentery, forming the smooth falciform ligament (Tortora and Derrickson, 2008, p. 945). The right lobe is five to six times bigger than the left lobe. The liver has a smooth texture and is a vascular organ rich in blood vessels that impart it a reddish brown color. It has an intricate and interconnected network of liver cells called hepatocytes, along with large amounts of ducts and veins (Chopra, 2001, p. 4).... 4).

The liver has a smooth texture and is a vascular organ rich in blood vessels that impart it a reddish brown color. It has an intricate and interconnected network of liver cells called hepatocytes, along with large amounts of ducts and veins (Chopra, 2001, p. 4). The hepatocytes, which are the principal liver cells, constitute almost 70% of the entire mass of the liver and are derived from the embryonic endoderm (Zorn, 2008, para. 3). Although some anatomists believe that the right lobe has an inferior quadrate lobe and a posterior caudate lobe, studies based on internal morphology and the distribution of blood vessels reveal that these two lobes more appropriately belong to the left lobe (Tortora and Derrickson, 2008, p. 945). The smooth falciform ligament that divides the two lobes of the liver extends from below the diaphragm, thereby helping the liver to stay suspended in the abdominal cavity. A round ligament, called the ligamentum teres, which is a remnant of the fetal umbilical vein, is present in the free border of the falciform ligament and extends from the liver to the umbilicus. A pear-shaped sac called the gall bladder is located in a depression that is present on the posterior surface of the liver. It hangs from the anterior-inferior margin of the liver and measures 7-10 cm. An analysis of liver histology reveals that it consists of bile canaliculi and hepatic sinusoids, apart from hepatocytes. The hepatocytes (liver cells) are

Motivation in the Work place - Dissertation Example This further enhances the challenge that organizations face. With the aim to ascertain how motivation affects the performance of employees in the workplace, three objectives and several research questions were presented in Chapter I. Based on a quality study comprising of secondary data, all the study objectives have been achieved. The study finds that the primary motivation factors continue to be financial incentives regardless of age and sector. However, once the basic needs are satisfied, individuals differ across their needs and consequently, motivation and thereby performance. This is where managerial competence is required. The study also finds that managers themselves are either ill-equipped or not satisfied with the motivation they receive. Nevertheless, they try to apply the same motivation techniques with their subordinates, which they themselves aspire. These include autonomy, authority in decision making and transparency. The study also finds that linking financial incent ives to performance usually do not work and other reinforcing factors such as appreciation, recognition, challenging assignments and clarity of job role have a role to play in positively impacting employee performance. In addition, effective communication, involvement, higher expectations motivate and lead to higher performance. Training is also critical to motivation and consequently employee performance. Transformational leadership has been identified as critical to managing employee motivation. The study concludes that motivation would differ across sectors and industries; it would also differ across individuals and their level of maturity. Therefore, there cannot be predefined motivation tools and techniques. However, managers would need to evaluate individual needs, talent and what drives them to enhance their performance. The study finds a definite correlation between motivation and employee performance. However, financial incentives are superior to other forms of incentives i n the beginning of an individual’s career. It is therefore recommended that managers should focus on individual employee needs and motivation. Effective communication, transparency, employee involvement, sharing of information and honesty could help managers understand employee needs and implement the most suitable motivation technique.
