Lymphatic

• Lymphatic System - picks up fluid leaks from the blood vessels and returns it into the blood stream.
• Lymphatic system - disposes of debris in the lymphatic stream.
• Lymphatic system - houses white blood cells involves in the immunity.
• Lymphatic System - meandering network of lymphatic vessels.
• Lymphatic system - lymphoid tissues and organs scattered throughout the body.
• Lymph - is a tissue entering lymph capillaries.
• Lymph Production - a biological fluid produced as an affluent or interstitial fluid from most parenchymal organs.
• Lymph functions

  • Collects products of tissue and transports them into regional lymph nodes.
  • Maintenance of immunological tolerance.
  • Autoimmunity
  • Inflammation
  • Cancer metastasis
  • Cardiovascular disorders
  • Metaboluc disorders
• Drainage - involves one open blunt-end at lymohatic capillaries which facilitates the drainage of the interstitial fluid at the movement of immune cells and apoptopic cells into the lymphatic circularion.
• A system of lymph vessels that begins as dead-end lymph capillaries found in most tissue spaces.
• Lacteals - specialized lymph capillaries in the vili of small intestine.
• Circulation - Mechanism is similar to venous return as that of blood vessels.
• Cisterna chili - Located in front of lumbar vertebrae where lymph vessels of the lower extremities unite
• Lymphatic tissue - Mainly it is consists of lymphocytes in a mesh-like framework of connective tissue.
• Lymph nodes - Larger than nodules, measures from 10 to 20 mm in length.
• Lymph nodes -They are found in groups along the pathways of lymph vessels where lymph flows through on its way to subclavian veins.
• Plasma Cells - They develop from lymphocytes exposed to pathogens in the lymph and produce antibodies.
• Cervical lymph nodes - The referred lymph node when we do denote a “swollen glands”.
• Cervical lymph nodes - It involves a condition known as Hodgkin’s Disease.
• Hodgkin’s Disease - A malignant disorder of the lymph nodes with NO KNOWN CAUSE.
• Hodgkin’s Disease - First symptom: swollen but painless lymph node.
• Hodgkin's Disease - Other symptoms: chronic fever, fatigue and weight loss.
• Hodgkin’s Disease - Dx: involves biopsy of the lymph node; characterization of cells.
• Nodules/Lymph nodules - Small masses of lymphatic tissue found just beneath the epithelium of all mucous membrane.
• Nodules/Lymph nodules - Measurement ranges from fraction of a millimeter to several millimeters in length.
• Peyer’s patches - Lymph nodules of the small intestine.
• Spleen - Contains fixed macrophages (RE cells) that phagocytize pathogens or other foreign material in the blood. The macrophages of the spleen also phagocytize old red blood cells and form bilirubin.
• Thymus - Stem cells produce T lymphocytes or T cells.
• Thymic Hormones - Enables the T cells to participate in the recognition of foreign antigens and to provide immunity.
• Immune system - It is a network of cells, tissues, and organs that protect the body against foreign organisms such as bacteria, viruses, parasites and fungi.
• Immune system - It is capable of identifying and remembering different foreign invaders and can produce secretions and cells to counter each.
• Immune system - It produces antibodies and stimulates certain specialized cells as a response to foreign organisms that gain access to your body.
• Immune system - It stands as guard over the body’s cells to make sure that they do not generate or turn abnormal and become harmful.
• Immunity - It is the ability to destroy pathogens or other foreign material and to prevent further cases of certain infectious diseases.
• Immune mechanism - Function to protect the body from the microorganisms around us and within us.
• Immune mechanism - Function to protect the body from the microorganisms around us and within us.
• FIRST LINE OF DEFENSE - Includes surface barriers that prevent the entry of pathogens into the body.
• SECOND LINE OF DEFENSE - Includes the non-specific phagocytes and other internal mechanisms that comprise innate immunity.
• THIRD LINE OF DEFENSE - Are specific lymphocytes that produce antibodies as part of the adaptive immune response.
• First line of defense

  • Skin
  • Mucous membrane
  • Secretions of skin and mucous membranes.
