Immuno Flashcards
body’s specific protective response to an invading foreign agent or organism
Immunity
study of protection from foreign macromolecules or invading organisms and the body’s responses to them
Immunology
study of diseases resulting from dysfunctions within the immune system
Immunopathology
how your body recognizes and defends itself against bacteria, viruses, and substances that appear foreign and harmful
Immune System
Primary functions of Lymphatic & Immune System
- Draining excess interstitial fluids
- Transporting dietary lipids
- Carrying out immune responses
a natural or artificial channel through which something (as a fluid) is conveyed
Conduits
The circulatory system processes an average of how many liters of blood per day?
20 liters
How many liters of the filtered plasma actually get reabsorbed directly into the blood vessels?
17 L
How many liters are left behind in the interstitial fluid?
3 L
Primary Lymphatic Organs
- Bone Marrow
* Thymus
Secondary Lymphatic Organs
- Lymph Nodes
- Lymph Nodules
- Tonsils
- Peyer’s Patches
- Spleen
MAJOR COMPONENT OF IMMUNE SYSTEM
- bone marrow,
- WBCs
- lymphoid tissues
Mass of soft tissue behind the nasal cavity, WBC circulate through the adenoids & other lymphoid tissue, reacting to invaders
Adenoids
small masses of lymphatic tissue found through the ileum region of the small intestine.
Peyer’s Patches
they monitor intestinal bacteria populations and preventing growth of pathogenic bacteria in the intestine
Peyer’s Patches
Other term for Peyer’s Patches
Aggregated lymphoid nodules
Found in medullary cavities of long bones & spaces of spongy bone
Bone marrow
production site of the WBCs involved in immunity.
Bone marrow
key component of the lymphatic system, producing the lymphocytes that support the body’s immune system.
Bone marrow
Store energy, insulate us and protect our vital organ. They also act as messenger, helping protein to do their jobs
Triglycerides/fats
mature in the bone marrow and then enter the circulation
B lymphocytes
move from the bone marrow to the thymus, where they mature into several kinds of cells capable of different functions
T lymphocytes
Process wherein your thymus decreases in size after puberty
Thymic involution
Reservoir of mature T lymphocytes
Thymus
Cells of the immune system involved in defending the body against both infectious disease and foreign materials
WBCs/ Leukocytes
Leukocytes are produced and derived from a multipotent cell in the bone marrow known as?
Hematopoietic stem cell
Function of the Thymus
- Immature T cells migrates
- The epithelial cells secrete a hormone called thymosin
- The site of maturation of T cells
Cells on the thymus
Thymic Stromal Cell, Cells of the hematopoietic origin
Serve as a center for the production of phagocytes
Lymph Nodes
Located in the upper left portion of the abdominal cavity
Spleen
Two types of tissue in the spleen
White pulp, Red pulp
Cells that allow the body to remember and recognize previous invaders and help the body destroy them
Lymphocytes
Immature T cells
Thymosites
Small, localized collection of lymphoid tissue, usually located in the loose connective tissue beneath wet epithelial (covering or lining) membranes, as in the digestive system, respiratory system, and urinary bladder
Lymph Nodules
Hormone that stimulates the maturation of T cells after they leave the thymus and migrate to other lymphatic tissues.
Thymosin
Cells that chew up invading organism
Phagocytes
