Thymus is aprimary lymphoid organ which are critical cells of the adaptive immune system, this thymus function in immunity is that the lymphocytes produced in the bone marrow migrate to the thymus and are processed and t- cells undergo development , differentitation and clonal expansion and thymus processed lymphocytes are responsible for cell mediated immunity etc.the severe form of the tcell deficiences involve the cognetial absence or immaturity of the thymus gland digeorge syndrome,in this the thymus gland may be affected and t-lymphocyte production may be impaired resulting in low t-lymphocytes number and frequent infections( it is seen during fetal development) so they have increased susceptibility to viral fungal and bacterial infecions.
What specific impacts would failure of the thymus to develop embryonically have on the immune system...
20 Handout IG1-2 Matching Activity: Organs of the Immune System Match the organ of the immune system with its function primary or secondary Primary or Secondary? Then identify whether the organ is Organ Function A. Spleen adjacent tissues to filter foreign antigens from interstitial fluid Collects lymph fluid from B. Bone marrow cells and foreign antigens from the blood Removes old and damaged C. Lymph node Produces T cells to protect the body from foreign invaders D. Thymus The largest...
Pls help me fill in the blanks sir/maam
T cells mature in the thymus gland in response to that is secreted by the thymus gland. When a T cell leaves the thymus it has a unique These T cells are not able to recognize foreign invaders called _without help. The invader has to be presented to the T cell in a specific way by an __ protein. Immunity mediated by T cells and Tc cells is referred to as _immunity....

7. Autoimmune disease occurs when a. people do not get enough sleep. b. the immune system loses its effectiveness. c. the immune system attacks body cells rather than invaders. d. T-cells are reduced by 90%. e. malignant cells proliferate, producing a demand for numerous immune system response.

How can the immune system orchestrate protection from disease without killing us in the process IQ4: Homeostasis: A balance of the good and bad B- and T-lymphocytes are derived from bone marrow- derived lymphoid precursors. Before maturation, naive T-lymphocytes (T-cells) must pass through the thymus where they undergo positive and negative selection. A tumour encounters the immune system frequently during its progression from a neoplasia to carcinoma, which can often take several years. There are a number of host mechanisms...
What is an antigen? How does the immune system recognize antigens? Please be as specific as possible.
The innate immune system tends to have non-specific responses to pathogens with antimicrobial peptides. However, scientists create antimicrobial compounds which are very target specific. Explain the differences in strategy (specific vs non-specific).
The adaptive immune response is composed of highly specialized cells and processes that control or eliminate the invading pathogen. What are CD4+ cells? What are CD8+ cells? Explain why the immune system is able to generate a stronger, faster, and more effective response upon re-exposure to a pathogen. T-lymphoblastic lymphoma is a neoplasm of immature T-cell precursors called lymphoblasts and often starts in the thymus. Predict anatomical and physiological changes that would occur to the surrounding organs in the mediastinum...
