| Answer |
|
|
| LEUKOCYTE-INDUCING FACTORS are released by: |
injured cells |
| LEUKOCYTE-INDUCING FACTORS help defense by: |
Promoting rapid neutrophil release from red bone marrow |
| LEUKOCYTOSIS is a sign of: |
inflammation |
| CHEMOTACTIC AGENTS are Inflammatory Chemicals that: |
attract WBC's to area |
| MARGINATION (PAVEMENTING) is whenneutrophils: |
cling to capillary walls as blood flow slows down |
| DIAPEDESIS (EMIGRATION) is: |
neutrophils squeeze thru capillaries walls & into tissue spaces |
| What follows neutrophils into tissue spaces? |
monocytes follow neutrophils within hours |
| Monocytes change from phagocytic slugs into: |
MACROPHAGES-insatiable consumers |
| MACROPHAGES have lots of: |
lysosomes in their cytoplasm |
| Macrophages replace neutrophils: |
as primary agents at inflammation site |
| Macrophages are dominate at: |
sites of chronic inflammation |
| PUS may form-it is: |
dead/dying neutrophils, broken tissue cells & pathogens |
| INFECTIOUS GRANULOMAS are: |
tumor-like growths of macrophages housing resistant bacteria |
| What may be covered by a fibrous capsule? |
INFECTIOUS GRANULOMAS |
| 4 Types of transplants are: |
Autografts, Isografts, Allografts, & Xenografts |
| Autografts are when: |
self to self |
| Isografts are when: |
genetically identical, ie: between twins |
| Allografts are when: |
tissue is human to human |
| Xenografts is when: |
tissue is between different species |
| AIDS is when HIV (human immunodeficiency virus): |
causes destruction of defensive HELPER T-CELLS white blood cells |
| SCID is A/K/A |
severe combined immunodeficiency disease |
| Hypersensitivities refers to: 4 |
allergies, allergens, anaphylaxis and anaphylactic shock |
| Sarcoidosis (possibly autoimmune) |
causes formation of granulomas in body organs; often assoc. w/lungs |
| Leukocytosis is: |
increase in WBC's |
| During leukocytosis # of neutrophils: |
in blood increase four to five fold within a few hours |
| Phagocytosis is what type of defense? |
NON SPECIFIC BODY DEFENSE (NBD) |
| Phagocytes specialize in the: |
engulfment of foreign pathogens on a grand scale |
| Phagocytes have large numbers of: |
LYSOSOMES in the cytoplasm |
| RESPIRATORY BLAST is an alternative: |
method of pathogen destruction |
| RESPIRATORY BLAST is a form of defense where chemicals from the immune system: |
stimulate the phagocyte cells to release free radicals to destroy invaders |
