The Functions of Lymphatic System

Ninety percent of this swimming is returned to the capillaries, but the rest remains as interstitial politic, on with small protein molecules which also leak from the capillaries. When the compress of the interstitial roving builds up, it is resorbed by the lymphatic capillaries and is then known as lymph.

35.7 at that place is no pump in the lymphatic system much(prenominal) as the heart in the cardiovascular system, and the lymph flows because of a pressure gradient which comes from external sources (Applegate, 2000, 289). Contractions of skeletal muscle, respiratory works, and contraction of the savorless muscle within the walls of the lymphatic vessels cause the pressure gradient. Lymph movement is sporadic and much s pooh-pooh than the movement of blood done the blood vessels.

35.8 The terminal duct draining most of the luggage compartment is the pectoral duct (Applegate, 2000, 289).

35.9 The cisterni chyli is the name given to the beginning of the thoracic duct (Applegate, 2000, 288). It collects lymph from two lumbar trunks which drain the lower limbs, and from the intestinal trunk that drains the digestive organs.

35.10 Lymph collected from the small catgut by the lacteals contains fat and fat-soluble vitamins, so has a milky visual aspect because of the fat content(Applegate, 2000, 281). This lymph is known as chyle. Because the cisterni chyli receives lymph from the digestive system, it will appear

35.19 During the development and maturation process, the lymphocytes learn to blemish proteins and large molecules that belong to the proboscis and they recognize these as " self" (Applegate, 2000, 294). Molecules and proteins that atomic number 18 not recognized as "self" are interpreted as "non-self" and initiate an immune response.

Antigens which trigger such reactions are usually proteins or large polysaccharide molecules on cell membranes.

35.11 The right on lymphatic duct drains the fastness right quadrant of the body, including the right side of the head and neck, the right upper extremity, and the right side of the thorax (Applegate, 2000, 288).

35.24 The spleen filters blood in much the equivalent way as the lymph thickenings filter lymph fluid: it contains areas consisting mainly of lymphocytes surrounding arteries (white pulp) and venous sinuses containing blood and cords of lymphatic cells (red pulp) (Applegate, 2000, 290). The white pulp and the red pulp are same to the cortical and medullary areas of a lymph node. The tonsils consist of clusters of lymphatic wander containing lymphocytes and macrophages, so are analogous to the cortical areas of a lymph node and the white pulp of the spleen. All function in the same manner: to remove unwanted pathogens, damaged cells, and harmful substances from the body to protect it from disease.
