Chapter 16-Lymphatic System & Immunity 1. Explain the functions of the lymphatic system. The lymphatic system functions to balance fluid‚ lipid absorption (via lacteals=lymph capillaries) and defense. It removes toxins/pathogens‚ fight infections and transports excess fluid in the interstitial spaces and returns it to the blood stream. Lacteals absorb digested fats from small intestines and transports it to venous circulation. 2. Trace the general pathway of lymph from the interstitial

The Lymphatic System The Lymphatic System is very important. It helps with the Cardiovascular system‚ and our immune systems. The Lymphatic System is made up of two semi-independent parts. One is a network of lymphatic vessels. The other part is various lymphoid tissues and organs all over the body. The functions of the Lymphatic System transporting fluids that have escaped from the blood vascular system‚ and the organs house phagocytic cells and lymphocytes. Lymphatic vessels are an elaborate

The lymphatic system is an extensive drainage network that is closely connected to both the circulatory and immune systems. It is responsible for keeping bodily fluids in balance and defends the body against infections. It is made up of a network of very small tubes known as lymphatic vessels that carry lymph‚ a colourless fluid that contains a high number of white blood cells and resembles plasma‚ throughout the body. The major parts of the lymph tissue are located in the bone marrow‚ spleen‚ thymus

The Lymphatic System And Immunity The cells‚ tissues‚ and organs of the lymphatic system play a central role in the body’s defenses against a variety of pathogens‚ or disease-causing organisms. Acts against environment hazards‚ various pathogens‚ and internal threats. Lymphocytes (primary cell) are vital to or overcoming infection and disease. Lymphocytes respond to invading pathogens‚ abnormal body cells‚ and foreign proteins. They act to eliminate these threats or render them harmless

GE 259 Lymphatic System June 24‚ 2014 1. What is the significance of a lower-than-normal hematocrit? What is the effect of a bacterial infection on the hematocrit? A lower than normal hematocrit indicates anemia‚ a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to the body tissues. If you have a bacterial infection‚ your white blood cell count would increase because as the wbc’s are fighting off the infection they die off releasing a

The lymphatic system is an amazing system of the body which is responsible for cleaning up the messes made by other systems of the body. In doing so‚ the lymphatic system does several jobs in the body. According to the Cancer Research UK‚ the lymphatic system is in charge of draining lymphatic fluid back into the bloodstream from the tissues‚ filters lymph‚ filters the blood‚ and fights infections. Unfortunately‚ as the lymphatic system goes about its regular duties‚ cancer can appear in the lymph

Merit task- lymphatic system A detailed explanation as to how the lymphatic system protects the body showing use of at least 4 different types of information. It protects the body by the lymph nodes. They are hundreds of small lymph nodes clustered along the lymphatic vessels. They are bean shaped and less than 2.5cm long. Each is surrounded by a fibrous capsule. Strands of connective tissue from the capsule extend inwards and divide the node into compartments. Many reticulate fibres support

A) the structures of the lymphatic system: Within the lymphatic system‚ there are many organs that form the structure of the whole lymphatic system within the body‚ and these organs are also structured depending on what their function is. For example‚ an organ which is present within the lymphatic system is the lymph nodes. These lymph nodes are considered to be shaped similar to that of an oval and is roughly 1-2cm in size. Within the lymph nodes‚ there is a reticular network‚ which is able to

The lymphatic system is a part of the circulatory system‚ that consists of a network of vessels called lymphatic vessels. These vessels carry a clear fluid called lymph towards the heart. The lymphatic system is not a closed system. The circulatory system processes an average of 20 litres of blood per day through capillary filtration which removes plasma while leaving the blood cells. Roughly 17 litres of the filtered plasma actually get reabsorbed directly into the blood vessels‚ while the remaining
