| 1. | Conditions in which the immune system attacks the body's own cells. |
| 2. | Disorders where the body fails to recognize pathogens. |
| 3. | Diseases caused by overproduction of antibodies. |
| 4. | Illnesses resulting from underactive immune responses. |
| 1. | Tuberculosis | 2. | Covid-19 |
| 3. | Bronchial asthma | 4. | Rheumatoid arthritis |
Use of anti-histamines and steroids gives quick relief from:
1. Allergy
2. Nausea
3. Cough
4. Headache
| 1. | Rheumatoid arthritis | 2. | Bronchial asthma |
| 3. | Tuberculosis | 4. | Influenza |
| 1. | Creutzfeldt Jakob Disease | 2. | Rheumatoid arthritis |
| 3. | Oculo-cutaneous albinism | 4. | Diabetes insipidus |
| 1. | Primary immune responses caused by the proliferation of memory T cells against common pathogens. |
| 2. | Genetically transmitted inability to produce antibodies against environmental antigens. |
| 3. | Over-sensitised immune responses in which IgE-mediated release of histamine and other chemicals from mast cells produces inflammatory symptoms. |
| 4. | Cell-mediated immune suppression due to deficiency of helper T cells leading to opportunistic infections. |
The use of anti-histamine, adrenaline and steroids quickly reduce the symptoms of
(1) Fungal diseases
(2) Viral diseases
(3) Allergy
(4) Helminthic diseases
| Assertion (A): | Autoimmune diseases occur when the body’s immune system attacks its own cells. |
| Reason (R): | Autoimmune diseases are caused by the failure of immune cells where they recognize self-antigens as foreign, leading to an inappropriate immune response. |
