Lymph nodes when we are health
The lymphatic system is collected of lymph vessels, lymph nodes, and organs. The functions of this system include the absorption of excess fluid and its return to the blood stream, absorption of fat (in the villi of the small intestine) and the immune system function.
The lymphatic system is made up of groups of lymph nodes throughout the body, which are connected by a network of lymph vessels.
The lymphatic system:
• acts as a one-way drainage system transporting fluid from body tissues into the blood circulation
• contains white blood cells called lymphocytes, which fight infection
• gets rid of waste products produced by cells. The lymphatic system
Lymph fluid
This is the liquid that flows through the lymph vessels and the lymph nodes. It forms when excess liquid, from the fluid that surrounds all our body tissues, drains into small lymph vessels.
Lymph vessels are a network of tubes that go all over the body. Some are tiny channels just under the skin, which can be easily damaged if the skin is broken. Small lymph vessels join together to form larger lymph vessels, which pass through lymph nodes. The fluid then travels through larger lymph tubes and drains into the bloodstream.
Lymph nodes are found throughout the body, but mainly in the neck,

When the body is in good health the system has no problem in working as the lymph nodes filter and cleans the fluids in the bloodstream the lymph nodes are small, however when an infection occurs then things are slightly different as the lymph nodes increase in size and swell up this is because the lymphocytes are working hard to fight the infection. At times there is more waste than the liver and kidney can remove and this accumulates in the blood and lymph channel causing infections and illnesses like tonsillitis, appendicitis and fibrocystic
Consequently, the efferent arteriole, which filters blood away from the glomerulus, is tinier in diameter than the afferent arteriole, which carries blood into each glomerulus. This puts blood under high pressure in the glomerulus; thus it forces tiny molecules and liquid out of the capillary and into the Bowman’s capsule. Soon afterwards, the tiny and liquid molecules cross the epithelium of the Bowman’s capsule, the basement membrane and capillary wall in order to get into the Bowman’s capsule and to arrive in the nephron tubules. The consequence of this is that the filtrate (the tiny and liquid molecules) pass along the remainder of the nephron and helpful substances are reabsorbed along the route. Last of all, “the filtrate flows through the collecting duct and passes out of the kidney along the ureter” as mentioned by (Parson’s, R: p128).
ANSWER: The cell composition of blood composed of erythrocytes, leukocytes, and platelets where all except the WBCs perform their functions within the blood only which involves transport and coagulation for platelets. While the interstitial fluid like water within the spaces between cells. Lymph is just like leaked blood that is collected by the lymphatic system but cleansed of any foreign or waste materials because of lymph nodes (6, 5, 1 p. 400 ).
Works in conjunction with the blood supply to carry waste products away from the area.
One of the most important organs of the lymphatic system within the body's blood filter process is the spleen. This organ does a variety of things to help keep healthy blood available to be shipped to the body for pathogen-fighting purposes. The spleen normally is about a fist size. The oval clump of blood vessels intertwined with strands of connective tissue is separated into two parts. The blood vessels that make up a large content of the spleen, are called splenic sinusoids. The organ is normally found in the left upper part of the abdomen, above the stomach, it is mostly protected by the lower ribs. This particular organ is a definite vital part in cleaning the body's blood supply. In most cases people can live without their spleen (Rettner, 2013). This of course comes with extra precautions to help fight infections but a normal life can exist. The dark purplish red mass helps to filter the blood through its many passageways of blood vessels and is soft in texture.
The Circulatory system is responsible for the transport of blood throughout the body. The Circulatory system has many organs. The main components are the heart, the blood, and the blood vessels. It also consists of arteries, arterioles,
The lymphatic system are a complex network of specialised cells and organs that defend the body against infection. Lymphatic organs include the bone marrow, spleen, thymus gland, lymph nodes, tonsils, adenoids, appendix and clumps of tissue in the small bowel. A function of the lymphatic system is to nurture and mature the B and T-lymphocytes (white blood cells vital to immune function). Cancerous changes can take place
This fluid is expelled from the body's capillaries and gathers either under the skin or in the body's internal organs.
The purpose of this exercise is to learn about the lymphatic system and how it works and helps the human body. Why we need it and the components associated with the lymphatic system.
The lymph vessels are the vessels which carry tissue fluids in your body into the lymph nodes. Certain tumors spread along the lymphatic system, including lymphomas and Hodgkin disease. Lymphangiogram is also used to evaluate people who have swelling in the legs or may have a blockage in the lymphatic system.
The spleen is an organ of the immune system (lymphatic system). It function is filter the blood and maintain it in a healthy way. The spleen produces two types of pulp to perform its function, the red and the white pulp (Goodenough & McGuire, 2014). The red pulp filters the damaged blood cells, palates and foreign materials in the blood, so it recycles the blood. On other hand, the white pulp is composed from lymphocytes, macrophages and plasma cells that help clean the blood. These two pulps work interchangeably to make sure the blood is filtered completely from any foreign materials and dead cells.
The lymph system carries away waste why draining the lymph capillaries. The fluid is them pushed along when a person breathers or muscles contract. The lymph capillaries have small opening that allow gases, water, and nutrients to pass though to nourish them and take away waste products. In addition the lymph system fights infection . They do this when the lymph fluid enters the lymph nodes the macrophages fight of bacteria removing the foreign bodies from the blood stream. When a person has a infection, germs collect in the lymph nodes which causes swelling.
The lymphatic system helps to protect us from infection and disease. It’s part of the body’s immune system. Lymph fluid passes through lymph nodes which are connected by a network of lymph vessels. The nodes are found throughout the whole body. My understanding of the lymphatic system is that it is a one-way drainage process that transports fluid from your body’s tissues into the blood circulation, it fights infections and gets rid of waste products produced by your cells. Lymph fluid normally flows through the network of lymph vessels that connect to a group of lymph nodes. The nodes, which are about the size of a baked bean and are located in specific parts of your body act as a filter, destroying or trapping anything harmful that the body
The lymphatic system works in three ways. It helps to control the balance of the body’s fluids by draining and cleansing fluid that seeps from the circulatory system during normal cardiovascular circulation. As fluid leaves the circulatory system it enters the tissue cells and whilst the majority of it diffuses back into the vessels of the circulatory system, the remainder enters the open ends of the lymph vessels. The lymphatic system also works with the villi in the digestive system to help deliver fats and absorbed nutrients in the digested food we eat, back to the circulatory system. This fluid is not called
The circulatory and immune systems are two very closely related systems. The circulatory is composed out of blood vessels, the heart, and blood. The immune system is made up of white blood cells and various lymph nodes. Basically, most of the immune system is found inside the blood of the circulatory system. The circulatory system provides the body with blood. It gives the kidneys of the digestive system something to filter and picks up nutrients from the small intestines. It also picks up air from the lungs of the respiratory system and provides the brain of the nervous system with blood, along with the rests of the body. Protection from wounds in the integumentary system is also provided by the circulatory system which has platelets that aid in blood clotting and forming scabs. The immune system protects all the other systems from disease and helps them from being attacked by viruses and bacteria. It also aids the ears of the nervous system with some very protective earwax. The circulatory system provides us with life fluid while the immune system protects that fluid and the rest of our body.
The system being attacked is the lymphatic system. We knew this because he was pronounced with edema. Edema is a condition where there is excess watery fluid in the cavities or tissues throughout the body. It was known that the lymphatic system returns leaked fluid to the blood vessels. The lymphatic system disposes of debris in the lymphatic stream. This system plays a very important role. It is in charge of housing the white blood cells that are involved in the immune systems.
