Immune Seminar
Bio 3 Seminar
| Question | Answer |
|---|---|
| What are the organs of the immune system? | Bone marrow, thymus, lymph nodes, spleen and MALT |
| What does the bone marrow do? | Maturation of B cells |
| What does the thymus do? | Differentiation of T cells |
| What does the lymph nodes do? | Prevalent aound armpits, groin and knees |
| What does the spleen do? | Filters blood and removes dead/malfunctioning cells |
| What does the MALT do? | Protects against micro-organisms by a mucus. Examples are the Peyer’s Patch in the small intestines, the respiratory, digestive and genitourinary tracts. |
| What are the 3 lines of defence? | 1) Innate nonspecific physical barrier 2) Innate nonspecific cells 3) Adaptive specific defenses |
| What is included is innate nonspecific physical barrier? | Mucus and skin |
| What is included is innate nonspecific cells? | Phagocytes (Macrophages, neutrophils and natural killer cells), inflammation and fever |
| What is included is adaptive specific defenses | Lymphocytes, antibodies and memory cells |
| Name 2 type of cells and what they do | 1) B cells: Produces plasma cells that secretes antibodies 2) T cells: Regulates other cells |
| How does B cells work? | Can recognize part of an epitope (portion of an antigen) that may or may not be a protein. Can be activated by co-receptors. |
| How do T cells work? | Contain a specific receptor called TCR that recognizes small chains of peptides in certain protein molecule |
| What are the 3 diseases associated with the immune system? | Diabetes type 1 (Not enough insulin produced), HIV-AIDS (HIV is virus and leads to AIDS) and theumatoid arthritis (Joint pain, inflammation) |
| What are the causes of type 1 diabetes? | The immune system attacks and destroys insulin-producing cells (beta cells) in the pancreas. |
| What causes HIV-AIDS? | HIV destroys white blood cells. |
| What causes rheumatoid arthritis? | Overeactive immune system attacking its own joint tissues instead of intruders lol |
| What are the symptoms of type 1 diabetes? | Increased thirst, intense hunger, fatigue, weakness, blurred vision. |
| What are the symptoms of HIV-AIDS? | Flu-like symptoms: fever, weakness, muscle pain, swollen glands, rashes... |
| What are the symptoms of rheumatoid arthritis? | Tender/swollen joints, pain and stiffness in joints, fatigue, loss of appetite. Can expand to the skin, eye, heart... dla marde |
