Lymphatic capillaries
|
Lymphatic vessels begin in the tissues and carry the fluid that forms there
|
|
|
Lymph
|
Interstitial fluid that enter lymphatic vessels
|
|
|
Thoracic duct
|
Main lymph collecting duct, receives lymph from the left side of the head, neck, and chest, left upper limbs, entire body below ribs
|
|
|
Primary lymphatic organs
|
Red bone marrow and thymus - where stem cells divide and develop into mature B and T cells
|
|
|
secondary lymphatic organs
|
Include lymph nodes, spleen, lymphatic nodules -most immune responses
|
|
|
Thymus
|
Organ where stem cells develop into mature T lymphocytes.
|
|
|
Red bone marrow
|
Stem cells divide and develop into mature B and T lymphocytes
|
|
|
Secondary Lymph Organs
|
Tonsils, lymphatic Vessels, Spleen, Thoracic and Right Lymphatic Ducts, lymphatic capillaries, lymph nodes
|
|
|
Afterent lymphatic vessel
|
Carry lymph from capillaries to nodes
|
|
|
Efferent lymphatic vessels
|
Carry lymph away from the node
|
|
|
Lymphocytes
|
major immune cells, B and T, a type of white blood cell that helps carry out cell-mediated and antibody-mediated immune responses.
|
|
|
Pathogens
|
Debris an disease causing organisms
|
|
|
Spleen
|
Between stomach and diaphragm, consists of white pulp an red pulp
|
|
|
White pulp
|
Is lymphatic tissue consisting mainly of lymphocytes and macrophages, which filter blood to remove debris and pathogens
|
|
|
Red pulp
|
Consists of blood filled sinuses with red blood cells, macrophages, lymphocytes, plasma cells and granular leukocytes. Worn out blood cells are destroyed and RBC and platelets are stored
|
|
|
Innate immunity
|
First line of defense - skin, mucus, saliva, tears, digestive system, urine flow. Try to block anything that can cause harm.
|
|
|
Adaptive immunity
|
Can remember the particular antigens that have invaded the body.
|
|
|
Antigen
|
A substance that has the ability to provoke the immune response
|
|
|
Phagocytosis
|
The process by which phagocytes ingests particulate matter, the ingestion and destruction of microbes
|
|
|
Complement Proteins
|
Form holes in microbial membranes forming them to burst
|
|
|
Interferons
|
Proteins formed to migrate to infected cells and interfere with replicating
|
|
|
Iron binding proteins
|
Inhibit the growth of certain bacteria by reducing the amount of available iron
|
|
|
Antimicrobial Proteins
|
Short peptides that kill microbes and attract other cells that participate in immune responses
|
|
|
Inflammation
|
A defensive response of the body to tissue damage
Redness, pain, heat, swelling. |
|
|
Cell-mediated Immunity
|
Effective against intracellular pathogens, inside cells
T Cells - made in red bone marrow and thymus gland Cells attacking cells |
|
|
Antibody-mediated immunity
|
Effective against extracellular pathogens
B Cells - red bone marrow |
|
|
Allergen
|
An antigen that evokes hypersensitivity reaction
Dander, pollen, poison ivy, bee stings, |
|
|
Histamine
|
Reexposure to an allergen. Substance found in cells that is released when the cells are injured
|
|
|
Active immunity
|
Own body develops antibodies
|
|
|
Passive immunity
|
Receiving antibodies
|
|
|
Vaccination
|
Receiving a vaccine
|
