Gray's Anatomy - Introduction - Yahoo! Reference Lymph capillaries of the cutis from the inner border of the sole of the human foot. —Lymph, found only in the closed lymphatic vessels, is a transparent, colorless, or slightly yellow, watery fluid of specific gravity about 1.015; it closely resembles the blood plasma, but is more dilute. The arteries of the gland enter at the hilus, and either go at once to the gland pulp, to break up into a capillary plexus, or else run along the trabeculæ, partly to supply them and partly running across the lymph paths, to assist in forming the capillary plexus of the gland pulp. messenger.yahooligans.com /reference/gray/175.html

Lymphatics.net: Information on the lymphatic system, lymph nodes, capillaries and edema Lymph is composed of water, ions, protein, clotting factors, lymphocytes, and fats absorbed from the intestine. Lymph is moved along within the system mostly by the action of external forces such as muscle contractions or changes in intrathoracic pressure with respiration. Lymph collected from the tissues is transported along thin-walled valved vessels to larger lymph vessels to drain into the venous blood via the thoracic and right lymphatic ducts. www.lymphatics.net   (586 words)

Lymphatic Vessels and Lymph (from lymphatic system) --  Britannica Student Encyclopedia Lymph diffuses from body tissues into lymph capillaries. Lymph nodes are located along the course of lymphatic vessels, which penetrate the nodes and carry a fluid called lymph. The major parts of the system are the lymph nodes, tonsils, thymus, spleen, and lymphatic vessels; additional lymphatic tissue is found in isolated patches in the gastrointestinal tract, lungs, and bone marrow. www.britannica.com /ebi/article-204115   (586 words)

The Lymphatic System as a drainage system Lymph capillaries branch and interconnect freely and extend into almost all tissues of the body except the CNS (Central Nervous System) and the avascular tissues such as the epidermis and the cartilage. Lymphatics from the lower portion of the body converge to form a dilated lymph vessel, the cisterna chyli, in the lumbar region of the abdominal cavity. Thus the lymph leaving the node is both cleaner of debris and richer in lymphocytes. www.jdaross.mcmail.com /lymphatics2.htm   (711 words)

Introduction to the Lymphatic System This stimulates the flow of lymph that is already in the system and frees space for the flow of the lymph that is going to enter the capillaries during the treatment. Lymph is the 10 percent of the tissue fluid that is left behind. Lymph nodes also trap cancer cells and slow the spread of the cancer until they are overwhelmed by it. www.lymphnotes.com /article.php/id/151   (711 words)

The Lymphatic System Experts call the lymphatic system a secondary circulatory system, because it assists the bloodstream with millions of tiny ducts that collect tissue fluid not needed by the capillaries or skin and returns it to the heart for recirculation. As all patients who have had lymph nodes removed know, circulation is generally worse after the loss of nodes: swelling, serious edema, and the need for medical procedures to remove fluids are all part of the aftermath of these procedures. The integrity of the lymph system is dependent on immune cells in the liver that filter out harmful bacteria and destructive yeasts. healthychristianliving.com /lymphatic_system.htm   (711 words)

The Lymphatic System Some scientists consider this system to be part of the blood and circulatory system because lymph comes from blood and returns to blood, and because its vessels are very similar to the veins and capillaries of the blood system. Closely connected with the blood and circulatory system, the lymphatic system is an extensive drainage system that returns water and proteins from various tissues back to the bloodstream. Lymphadenopathy is an increase in the size of a lymph node or nodes, most often as the result of a nearby infection (for example, lymphadenopathy in the neck might be the result of an infection of the throat). www.gorhams.dk /html/the_lymphatic_system.html   (711 words)

LymphaticNotes.doc PASSAGE OF LYMPH The passage of lymph is from lymph capillaries to lymphatic vessels to lymph trunks to the thoracic duct or right lymphatic duct to the subclavian veins Lymph flows as a result of skeletal muscle contractions and respiratory movements Movement of lymph also aided by valves in the lymphatic vessels 6. LYMPHATIC VESSELS & LYMPH CIRCULATION Lymph vessels begin as closed-ended lymph capillaries in tissue spaces b/w cells Interstitial fluid drains into lymphatic capillaries, thus forming a lymph Lymph capillaries merge to form larger vessels called lymphatic vessels, which convey lymph into and out of structures called lymph nodes 4. LYMPHATIC SYSTEM The lymphatic system carries out immune responses and consists of lymphatic vessels, and structures and organs that contain lymphatic tissue (specialized reticular tissue containing many lymphocytes) The lymphatic system functions to drain interstitial fluid, transport dietary lipids, and protect against invasion through immune responses 3. www.xomat.com /LymphaticNotes.doc   (711 words)

316lx22 In the small intestine, the lymphatic capillaries are termed lacteals; some fats are absorbed into lacteal rather than blood capillaries) These unite to form Lymph capillaries begin as closed-ended vessels between cells; they have endothelial linings. Lymphatic vessels, which are like veins but more delicate and thinner-walled; they carry lymph to the www2.ic.edu /chapman/316lx_ch22.html   (711 words)

The Lymphatic System as a drainage system The three main types of lymphatic vessels are lymph capillaries, lymphatics, and lymph ducts. Lymph capillaries branch and interconnect freely and extend into almost all tissues of the body except the CNS (Central Nervous System) and the avascular tissues such as the epidermis and the cartilage. Lymphatics from the lower portion of the body converge to form a dilated lymph vessel, the cisterna chyli, in the lumbar region of the abdominal cavity. www.jdaross.mcmail.com /lymphatics2.htm   (711 words)

Introduction to the Lymphatic System Within the lymphatic capillaries there are one-way valves that ensure the continued flow of the lymph away from the tissues. This stimulates the flow of lymph that is already in the system and frees space for the flow of the lymph that is going to enter the capillaries during the treatment. The terminus is the area at the base of the neck where the lymphatic ducts return lymph to the circulatory by emptying into the subclavian veins. www.lymphnotes.com /article.php/id/151   (1083 words)

Introduction to the Lymphatic System This stimulates the flow of lymph that is already in the system and frees space for the flow of the lymph that is going to enter the capillaries during the treatment. This is followed by gentle strokes are used to encourage the flow of lymph into the capillaries. The functioning of the lymphatic system is closely related to that of the circulatory system. www.lymphnotes.com /article.php/id/151   (1048 words)

Lymphatic System/ Components of the Lymphatic System The smallest lymphatic vessels are the lymph capillaries, which begin in the tissue spaces as blind-ended sacs. Lymph capillaries are found in all regions of the body except the bone marrow, central nervous system, and tissues, such as the epidermis, that lack blood vessels. The lymphatic system consists of a fluid (lymph), vessels that transport the lymph, and organs that contain lymphoid tissue. training.seer.cancer.gov /module_anatomy/unit8_2_lymph_compo.html   (406 words)

Introduction to the Lymphatic System This stimulates the flow of lymph that is already in the system and frees space for the flow of the lymph that is going to enter the capillaries during the treatment. Lymph is the 10 percent of the tissue fluid that is left behind. Normally the amount of lymph circulating in the body is one to two quarts and it makes up one to three percent of the body weight [6]. www.lymphnotes.com /article.php/id/151   (1048 words)

Plan of Lymphatic system The lymph flows slowly through the lymph capillaries into small lymph veins which unite to form larger lymph vessels until they finally open into the two very large lymphatic ducts, viz. All the lymph vessels of the lower limbs, the internal organs, the left side of the chest, the left arm and the left side of the head and neck, drain into the large thoriac duct. The lumph vessel of the right side of the chest, the right arm and the right side of the head and neck drain into the right lymphatic duct. www.botany.uwc.ac.za /SCI_ED/grade10/manphys/plan.htm   (759 words)

Lymph Lymphatic capillaries are slightly larger in diameter than blood capillaries and have a unique structure that allows interstitial fluid to flow into, but not out of, lymphatic capillaries. Lymphatic capillaries are found everywhere in the body except: 1) avascular tissues, 2) the central nervous system, 3) the splenic pulp, and 4) bone marrow. Specialized lymph capillaries are associated with the vili of the small intestine. www.clt.astate.edu /mgilmore/lymph.htm   (759 words)

The Lymphatic System as a drainage system Lymph capillaries branch and interconnect freely and extend into almost all tissues of the body except the CNS (Central Nervous System) and the avascular tissues such as the epidermis and the cartilage. The fluid is left in the system for 24 hours and the lymph nodes can then be observed by X-rays. Its microscopic dead-end capillaries extend into most tissues, paralleling the blood capillaries. www.jdaross.mcmail.com /lymphatics2.htm   (759 words)

MSN Encarta - Lymphatic System The lymphatic capillaries are more permeable than ordinary capillaries and allow passage of larger particles than would ordinarily pass through capillary walls; large-molecule proteins, produced as a result of tissue breakdown, pass into the lymphatics for transport away from the tissues. The lymphatic system is of primary importance in transporting digested fat from the intestine to the bloodstream; in removing and destroying toxic substances; and in resisting the spread of disease throughout the body. Lymphatic System, common name for the circulatory vessels or ducts in which the fluid bathing the tissue cells of vertebrates is collected and carried to join the bloodstream proper (see Lymph). encarta.msn.com /encnet/refpages/RefArticle.aspx?refid=761566336   (629 words)

Gray's Anatomy - Introduction - Yahoo! Reference The lymphatic capillaries and collecting vessels are lined throughout by a continuous layer of endothelial cells, forming thus a closed system. These lymph-sacs are developed by the confluence of numerous venous capillaries, which at first lose their connections with the venous system, but subsequently, on the formation of the sacs, regain them. The lymphatic capillaries have not been followed into the liver lobules. messenger.yahooligans.com /reference/gray/175.html   (629 words)

The Lymphatic System Experts call the lymphatic system a secondary circulatory system, because it assists the bloodstream with millions of tiny ducts that collect tissue fluid not needed by the capillaries or skin and returns it to the heart for recirculation. The integrity of the lymph system is dependent on immune cells in the liver that filter out harmful bacteria and destructive yeasts. There are specialists in manual lymphatic drainage, a very delicate massage technique taught in Austria (called the Vodder method) who are trained to help reroute lymph flow so as to by-pass the normal channels, the ones that have been removed. healthychristianliving.com /lymphatic_system.htm   (1682 words)

· LYMPHATIC SYSTEM Networks of lymphatic capillaries are located in the intercellular spaces and are widely distributed throughout the body. This problem is avoided by the presence of lymphatic vessels that act as "drains" to collect the excess fluid and return it to the venous blood just before it reaches the heart. Although there is no muscular pumping organ connected with the lymphatic vessels to force lymph onward as the heart forces blood, still lymph moves slowly and steadily along its vessels. linux.cayuga-cc.edu /greer/biol204/lymphatic1/lymphatic1.html   (867 words)

Lymphatic System/ Components of the Lymphatic System The smallest lymphatic vessels are the lymph capillaries, which begin in the tissue spaces as blind-ended sacs. Lymph capillaries are found in all regions of the body except the bone marrow, central nervous system, and tissues, such as the epidermis, that lack blood vessels. Lymphatic organs are characterized by clusters of lymphocytes and other cells, such as macrophages, enmeshed in a framework of short, branching connective tissue fibers. training.seer.cancer.gov /module_anatomy/unit8_2_lymph_compo.html   (867 words)

Chapter 22 Lymph moves from the tissues into the lymphatic capillaries that join to form into lymphatic vessels, the vessels join to form lymphatic ducts and ultimately empties into the subclavian veins. Lymphatic capillaries can be seen in various tissues except in the central nervous system (brain and spinal cord), in the avascular tissue and in the bone marrow. The lymphatic vessels are like the veins in structure, but their walls are thinner, and they have many valves. www.gpc.edu /~pahanotu/lymphatics.htm   (867 words)

Cr. HandiworkMAN In the center of each is a lymph channel (lacteal), with blood capillaries surrounding it. If all your body were removed except your lymph vessels, the complete three-dimensional form of your body would still be there. That is how many lymph vessels there are in your body! www.evolution-facts.org /Ev-V3/3evlch36.htm   (867 words)

THE MERCK MANUAL--SECOND HOME EDITION, Introduction in Ch. 37, Lymphatic Disorders Lymphatic vessels, located throughout the body, are larger than capillaries, and most are smaller than the smallest veins. The lymphatic system may not perform its function adequately when the quantity of fluid is excessive or when the lymph vessels or nodes become blocked by a tumor or become inflamed. The rest of the fluid (lymph) is drained from the spaces surrounding the cells into the lymphatic vessels, which eventually return it to the veins. www.merck.com /mmhe/sec03/ch037/ch037a.html   (867 words)
