Essay On The Lymphatic System

1331 Words6 Pages

The diagram above explains the fact that the lymphatic system is part of the circulatory system and plays three major roles which may include the removal of excess fluids including red blood cells from the body, absorption of fatty acids as well as helping to transfer fatty substances and chyle to the circulatory system. And, it helps in the production of lymphocytes, monocytes, and antibody producing cells which help to strengthen our immune system against any invaders that make us sick. Like the cardiovascular system, the lymphatic system is made up of vessels. Although, it lacks a heart that pumps blood such as what is obtainable in the cardiovascular system, the lymphatic system has got lymph which is produced as blood plasma that is discharged from the capillaries of the circulatory system via skeletal muscle contraction. The lymphatic system has also got valves and lymph nodes to prevent backflow.
Information contained in my class notes point to the fact that lymph nodes can only be found at …show more content…

Insulin signals the liver, the muscle and the fat cells to increase their anabolic activities by absorbing glucose from the blood. Insulin is released when either glucose is present in our body or protein is ingested in our system. Body cells are able to absorb glucose from the blood because of the presence of insulin. Without insulin, it will be impossible for glucose to enter our cells and without glucose in our cells, they will not be able to function properly. Thus, insulin regulates how the body stores and uses glucose and fat inside the body system. Glucose is stored in the liver and muscles as glycogen and in so doing, the body will stop using fat as a source of energy. The body will only resort to using fat as a source of energy when there is a shortage of insulin in our body system

    The supply of glucose to the brain and immune system is important as competitors constantly rely on instantaneous decision making to ensure they make effective strategic moves. Glucagon is the hormone which ultimately increases blood glucose concentration by breaking down stored glycogen in muscle and fat cells, increasing the breakdown of fats and increasing liver glucose production. Each of these effects lead to an increased amount of glucose present in the bloodstream, meaning more energy for body cells. When the level of glucose in the bloodstream drops, more glucose is required in order to provide ATP for energy. The secretion of insulin by beta cells is inhibited

    It is seen when a lot of fat is consumed and is being metabolized at a high rate. The fatty acids that are present are getting converted into ketones. Ketosis takes place when the body is not getting enough energy from glucose. In diabetics, this takes place due to the body not producing enough insulin for glucose break down. One of the most commons ways it is tested in diabetics is with ketone strips.

    Non Hodgkin Lymphoma is the most frequently known forms of cancer that originates in the Lymphatic System. This disease is also known to be the sixth leading cause of death in Lymphoma patients in the United States. The Lymphatic System consists of lymph nodes that are found in certain organs and areas of the body. Lymph nodes contain many, many cells called lymphocytes, which are more commonly known as white blood cells. White blood cells are the body’s defense system against bacteria and infections.

    Our bodies take in the glucose and turn it into energy we can then use. When we let glucose in, we are raising our insulin and glucose levels. Insulin is the hormone in people’s bodies that grants glucose access into our bloodstreams. However, insulin keeps our blood levels from raising or lowering, and it stores the fat to use for energy later on. Unfortunately, people have no control over the insulin function, though they do have control over the types of food they eat that contain certain amounts of glucose.

    Similarly, as blood glucose falls, the amount of insulin secreted by the pancreatic islets goes down. Insulin has an effect on a number of cells, including muscle, red blood cells, and fat cells. In response to insulin, these cells absorb glucose out of the blood, having the net effect of lowering the high blood glucose levels into the normal range.

    The roles played by four key hormones in the body, namely Insulin, Adrenaline, Cortisol and Glucagon, become interconnected actions to insure metabolic regulation occurs in the human body. All four hormones are not just responsible for their own specific ‘task’ and are involved in a range of interconnected actions. The three key areas of paramount importance in metabolic regulation in the human body are glucose storage and mobilisation, protein storage and mobilisation and fat storage and mobilisation. The hormone insulin stimulates anabolic and inhibits catabolic process involved in carbohydrate, fat and protein metabolism in the human body. The hormones Adrenaline, Cortisol and Glucagon stimulate catabolic processes involved in carbohydrate, fat and protein metabolism in the human body (Newsholme,

    There are two kinds of adipose tissue cells namely white adipose tissue and brown adipose tissue (also name as brown adipocytes). White adipose tissue is most prevalent in our body, which have primary functions of accumulating free fatty acid for energy storage for the times of starvation or exertion, provides insulation and forms protective pads between organs. When muscles cells or other tissues need to consume energy stored in adipose tissue, epinephrine, norepinephrine, glucagon and adrenocorticotropin bind to adipose tissue cells and trigger the hydrolysis of triacylglycerol, causing the release of fatty acids and glycerol (Lipolysis). On the other hand, the brown adipocytes utilize available energy to generate heat to keep our body at a constant temperature.
