In addition to the blood system, our body has another transport system called the lymphatic system clear fluid leaks out of blood capillaries and surrounding tissue cells to cope with this leakage, fluid is able to drain into a system of tubes that increase in size from tiny lymph capillaries to lymph vessels to. Although lymphocytes are distributed throughout the body, it is within the lymphatic system that they are most likely to encounter foreign microorganisms lymphatic system: humanthe lymphatic system drains excess water from tissues and removes pathogens from the resulting liquid, known as lymph created and produced. One of the lymphatic system's major jobs is to collect extra lymph fluid from body tissues and return it to the blood this process is important because water, proteins, and other substances are continuously leaking out of tiny blood capillaries into the surrounding body tissues. Introduction to lymphatic system: lymphatic system (source: theemirr/ wikipedia) lymphatic system is the drainage system of human body and is accessory to the venous system at arterial ends of capillaries fluid leaks out and at the venous end, it is absorbed back in some of the fluid remains in the tissue spaces.
Major groups of lymph nodes are located in the tonsils, adenoids, armpits, neck, groin and mediastinum thymus: the thymus is a specialized organ of the immune system, located between the breast bone and heart it produces lymphocytes, is important for t cell maturation (t for thymus-derived) spleen: the spleen is an.

A major function of the lymphatic system is to drain body fluids and return them to the bloodstream a major distinction between the lymphatic and cardiovascular systems in humans is that lymph is not actively pumped by the heart, but is forced through the another type of lymphocyte of importance is the plasma cell.
Considering that the average human body only has about five or six liters of blood, you can begin to understand the importance of the lymphatic system these leaked fluids, along with any blood proteins that were forced out of the bloodstream, must be returned to the blood to maintain adequate blood volume also, if the. One important difference is that lymph passes through at least one lymph node or gland before it reaches the blood system (see diagram 102) lymph nodes are of various sizes and shapes and found throughout the body and the more important ones are shown in diagram 103 introduction to the lymphatic system. The lymphatic system is important for the optimal functioning of our general and specific immune responses the lymph nodes monitor the lymph flowing into them and produce cells and antibodies which protect our body from infection and disease the spleen and thymus are lymphatic organs that monitor the blood and.

Similar to the way your blood circulatory system delivers nutrients and oxygen to all cells of the body, the lymphatic system is a complex network of vessels that branch through all parts of the body to circulate important bodily fluid and defend against infection when functioning well, the lymphatic system.
Today hank explains your unsung lymphatic system and how it supports cardiovascular function by collecting, filtering, and returning interstitial fluid back into the bloodstream via a system of lymphatic vessels he also explains the system's major role in fighting off infection, and how lymph nodes, and other. There are between 600-700 lymph nodes present in the average human body it is the role of these nodes to filter the lymph before it can be returned to the circulatory system although these nodes can increase or decrease in size throughout life, any nodes that has been damaged or destroyed, does not.
Blood and lymphatic vessels fulfill important homeostatic functions such as providing nutrients for the skin and regulating the immunologic processes introduction lymphatic vessels are located in all tissues and organs of the body except the central nervous system these vessels collect extracellular tissue fluid (or. Introduction the lymphatic system is a frequently overlooked yet vitally important system in the body in addition to maintaining tissue fluid player in the body's response to pathogens and acts as the physical basis of the immune system by providing conduits and lymph nodes for the. Introduction the lymphatic system plays an essential role in systemic immunity, fluid homeostasis, and returning tissue fluid and macromolecules to the circulation lymphatic drainage plays a significant role in the pathology and treatment of breast cancer globally the most frequently diagnosed malignancy and leading. Lymphatic system consists of lymphatic vessels which contain lymph and lymphatic tissue – that can be arranged in lymphatic organs (thymus, spleen and lymph sentinel nodes are particularly important, they are constantly present in a human body and their alteration indicates in time about a disease of a specific organ.
