As the lymph enters the node, spaces or channels called sinuses collect and carry lymph toward an area called the hilum. Get ideas for your own presentations. Lymph contains disease-fighting cells called lymphocytes, which are supplied by the lymphatic system. Define and describe components of lymphatic system (lymph nodes and lymph vessels) 2. Contents. Comprehend the mechanism of production and circulation of lymph. In stark contrast to the blood vasculature, the lymphatic circulatory system has been far less extensively studied. Fig. Lymphatic vessels - Collect interstitial fluid and carry It (lymph), via a system of progressively larger vessels, into regional lymph nodes. Lymphatic drainage. The lymphatic system helps rid the body of toxins. Lymphatic drainage plays a significant role in the pathology and treatment of breast cancer; globally the most frequently diagnosed malignancy and leading cause of death due to cancer in women. Cell Structure. Lymphatic system consists of three parts. The lymphatic vessels, also called lymphatics, form a one-way system, and lymph flows only toward the heart. , Metastasis is the process by which a tumor cell leaves the primary tumor, travels to a distant site via the circulatory system, and establishes a secondary tumor. One of the primary functions of the lymphatic system is the movement of interstitial fluid from the tissues to the circulatory system. Understanding the lymphatic system PPT means using a proper diagram to allow for the right visualization of the process. How to stop lymph fluid leaking. the right side of the system deals with deoxygenated blood. About 500 – 600 lymph nodes are present in the human body. The human circulatory system circulates blood through two loops (double circulation) – One for oxygenated blood, another for deoxygenated blood. Circulatory. Lymphatics. Elementary tissues: Elementary tissues of the body, i.e. Organs: lymph nodes (found in various locations), thymus, spleen - these constitute the lymphoid organs Thymus and bursa (bone marrow) are called central lymphoid organs Peripheral Lymphoid Organs: Except lymph nodes, spleen, and tonsils, liver, intestine and skin are also are also important parts of the immune system.

Disturbances in blood capillary exchange of fluid, macromolecules, and cells across intact and abnormal microvessels and deranged lymphatic transport are integral, interacting components in disorders of tissue swelling. The spleen’s main immunological function is to remove micro-organisms from circulation. Blood comprises of plasma, white blood cells, red blood cells, and platelets. Physiology/Hemodynamics . While initial study of the blood vascular system dates back to the sixth century BC, the lymphatic vasculature was not discovered until 1622 by Asellius. Anatomy & Physiology. Question. Lymphatic system, network of vessels and other tissues, including the tonsils, spleen, and thymus, that maintains fluid balance and fights infection. The lymph vessels, running away from the tissues, gradually merge together and form larger vessels. Blood circulation is a closed circuit, but many exchanges occur at the venular and capillary levels between blood tissue and perfused organs. Learn new and interesting things. The lymphatic circulation is devoid of any central pump. Returns interstitial fluid and leaked plasma proteins back to the blood. B Closed Circulatory System- blood is carried through blood vessels. Share yours for free! ROUTES & Mechanisms OF. The lymphatic nodules are arranged as sleeves around the blood vessels, bringing blood into the spleen. • Lymph carries protein and large particulate matter away from the tissue space.

It helps blocked lymphatic fluid drain properly into the bloodstream and may reduce swelling. The node is enclosed in a capsule and has an indentation on one surface (along one of its long axes) known as the hilum. Dynamics of lymph flow. The major routes into the lymph node are via afferent lymphatic vessels (see Figure 21.1.7). The Heart These are arteries. Function. நிணநீர் அமைப்பு என்றால் என்ன?Introduction to Lymphatic SystemWhat is the Lymphatic system? The microfilariae migrate into lymph and blood channels moving actively through lymph and blood . The circulatory system includes the lymphatic system, which circulates lymph. METASTASIS (Distant Spread) : It is defined as … •Insects, crabs, and other arthropods have an open circulatory system, in which there is no separation between blood and other intracellular fluid. Lymphatic Vessels. Diabetes Mellitus (both Type 1 and Type 2) is now a global epidemic. The blood in our circulatory system is a watery based fluid and consists of two basic components: 1) Plasma (55%) and, 2) Formed elements (45%) Part A: Plasma The Plasma is the light yellow liquid portion of the blood and is about 90% water. From here, around 75% of lymph (mostly from the lateral quadrants of the breast) drains into the pectoral lymph nodes, and then into the axillary lymph nodes.Whilst the remainder drains into the parasternal lymph nodes.This is why axillary lymph nodes are the … MLD is a specialized technique that involves gentle skin massage. The lymph vessels collect in the lymph nodes where potential bacteria and viruses are attacked and removed. For best results, you should begin MLD treatments as close to the start of lymphedema as possible. • Lymph vessels will ultimately join these lymph sacs in an organized fashion. II) Variety of closed circulatory systems. Gross anatomy. The lymphatic vessels are the third component. Wounds, animal bites, or other breaks in the skin and mucous membranes can result in the rapid dissemination of bacterial pathogens throughout the body. Many are downloadable. Lymph is also a fluid connective tissue that is released as blood passes through capillaries in tissues. Unit 3.

Introduction Routes of Metastasis Lymphatic Route Hematogenous Route Direct Spread Mechanism of Metastasis Bibliography. The lymphatic system includes a network of vessels, ducts, and nodes, as well as organs and diffuse tissue that support the circulatory system. Lymphatics are small (the most-studied ones are microscopic) with thin transparent walls; they convey a transparent fluid at low velocity and flow-rate. Lymph flows from the lymphatic capillaries, through lymphatic vessels, and then is dumped into the circulatory system via the lymphatic ducts located at the junction of the jugular and subclavian veins in the neck. Afferent carries lymph to lymph nodes. Lymphatics of the Lungs Thomas W. Shields The lung has an extensive network of lymphatic vessels that are situated in the loose connective tissue beneath the visceral pleura, in the connective tissue in the interlobular septa, and in the peribronchial vascular sheaths. From the lymph nodes the lymph flows further and enters the blood circulation through the left subclavian vein in the thorax. veins. The lymphatic system could be referred to as a specialized component of the circulatory system. Answer. Most of this fluid is collected in the capillaries of a secondary circulatory system, the lymphatic system. Extracellular fluid in the lymphatic system is known as lymph. Lymph is composed mainly of plasma, and loads of metabolic wastes that have been exuded by hard working cells. During the last 20 years a deeper understanding of the lymphatic circulatory system, lymph formation and composition has emerged. Lymph node is located in the lymphatic system, which is distributed throughout the body. Lymph flows from small lymph capillaries into lymph vessels that are similar to veins in having valves that prevent backflow. The crucial features of the human circulatory system are as follows: The human circulatory system consists of blood, heart, blood vessels, and lymph. About 500 – 600 lymph nodes are present in the human body. Question. Question.

CIRCULATION dr.aari 2. dr.aarif Circulatory System Blood Vascular System Lymphatic System Blood Heart Blood Vessels Lymph Lymph vessels Lymph nodes Functions of circulatory system: 1. (via afferent lymphatic vessels).-Lymph leaves the lymph nodes via efferent lymphatic vessels, which eventually drain back into the circulatory system (via the thoracic duct). Manual Lymphatic Drainage: Lymphatic drainage is a form of gentle manual therapy that encourages the movement of lymph fluids around the body. The SlideShare family just got bigger. Human Embryology, 3rd Ed., p. 445 • Lymphatic development: • ‘Two large channels (right and left thoracic ducts) connect the jugular lymph sacs with the cistern. From here, lymphatics pass to the tracheobronchial nodes, which drain into the bronchomediastinal trunk on each side. On SlideShare. Human Anatomy and Physiology : The Lymphatic System; Ziser Lecture Notes, 2014.3 1 The Lymphatic System network of tissues, organs and vessels that help to maintain the body’s fluid balance & protect it from pathogens like the circulatory system, the lymphatic system consists of “pumps”, a series of vessels, and a fluid called lymph Efferent lymphatic vessels take lymph away from the lymph node. Typically, approximately one to three popliteal nodes and two to 10 ilioinguinal nodes are visualized . Question. It is essential to find out about lymph in the study of body fluids and circulation. 1. The Heart. The lymphatic system is one of the most complex in the human body, reaching all points from the head down to the toes. Collects fluid lost from ... B. It creates a one-directional flow of lymph towards the heart. The lymph from the major portion of the body flows through the thoracic duct while that from the right upper quadrant drains into the right lymphatic duct. Groups of lymph nodes are present in the neck, collarbone, under the arms (armpit), and groin. The body fluids and circulation of these body fluids is described below in complete detail. Lymphatic System Notes. After naïve lymphocytes are produced in the thymus or bone marrow, they enter the blood, where they spend about 30 min, before migrating to the lymphoid and nonlymphoid organs. Vagus (parasympathetic) C + T sympathetic chain ganglion. The Function of the Lymphatic System. 1 atrium & 1 ventricle. Once this collection of substances enters the lymphatic vessels, it is known as lymph. The IMMUNE System. The lymphatic system is a series of vessels and nodes that collect and filter excess tissue fluid (lymph), before returning it to the venous circulation. That is where a good lymphatic system PowerPoint diagram can really help in presentations. In normal circulation, the oxygenated blood leaves the left side of the heart through very large … Lymph enters the lymph node via the subcapsular sinus, which is occupied by dendritic cells, macrophages, and reticular fibers. Lymphatic circulation begins with lymphatic. the thymus is a primary lymphoid organ essential for the development of t lymphocytes which orchestrate adaptive immune responses. the left side of the system deals with oxygenated blood. This slideshow is intended for students in Mr. Hildebrandt's anatomy & physiology classes. Lymph spreads through the subcapsularsinusoverthelobule’sapex,flowsdownthesides of the lobule through transverse sinuses and then flows into the medullary sinuses. Transport of nutrients from the digestive organs to different tissues. The lymphatic system could be referred to as a specialized component of the circulatory system. Groups of lymph nodes are present in the neck, collarbone, under the arms (armpit), and groin. The fluid in the lymphatic system helps remove waste and toxins from the bodily tissues. These structures help to filter harmful substances from the bloodstream. Produces white blood cells … LYMPH CIRCULATION There are certain tubular vessels that are responsible for transporting lymph back into the blood stream, thus, ultimately replacing the volume of blood lost during interstitial fluid formation. b) Lymphatic System: 1. In liver, kidney, lungs, heart, pancreas and many endocrine glands the lymphatic network is much smaller than the blood vessels network. slideshare.netManual lymphatic drainage (MLD). The lymphatic system is a conduit for travel and communication between tissues and the bloodstream. In general, the lymphatic vessels that drain the peripheral areas of the body parallel the venous return. Circulation 1. • Lymph sacs can be thought of as focus points for the developing lymphatic system. 1. Lymphatic system: The lymphatic system is a network of vessels and tissues composed of lymph, an extracellular fluid, and lymphoid organs, such as lymph nodes. The hilum is the point at which arteries carrying nutrients and lymphocytes enter the lymph node and veins leave it. Cardiovascular System = Heart, Blood and Vessels. Although the circulatory system is a closed system, bacteria can enter the bloodstream through several routes. Wounds, animal bites, or other breaks in the skin and mucous membranes can result in the rapid dissemination of bacterial pathogens throughout the body. Lymph flow depends, predominantly, on local pressure effects and intrinsic contraction of the larger lymphatics. Like the veins of the circulatory system, lymphatic capillaries and vessels move lymph with very little pressure to … arterioles. If the cancer metastasizes to other tissues or organs it usually dramatically increases a patient's likelihood of death. slideshare.net. Scope of Anatomy and physiology. LYMPHATIC CIRCULATION The lymph is moved through the body in its own vessels making a one-way journey from the interstitial spaces to the subclavian veins at the base of the neck. Since the lymphatic system does not have a heart to pump it, its upward movement depends on the motions of the muscle and joint pumps.
