Microbio host-parasite relationships OBJ 7
Terms in this set (30)
Describe the function of serum, plasma, lymph, lymph nodes, granulocytes, and agranulocytes...with emphasis of their role in resistance.
List the 3 components of blood.
2. clotting factors
- the fluid portion of blood
- the vehicle for all the stuff in the blood
- composed of
-- mostly water
-- some dissolved salts
-- other molecules
clotting factors =
- proteins produced by the liver that keep you from bleeding to death
- stops bleeding
People with which condition have blood that cannot clot so need injections of clotting factor to be able to live?
serum + clotting factors
plasma can clot...serum cannot
List 3 types of cells in blood.
2. platelets (thrombocytes)
What is the primary job of RBC's?
transporting O2 to cells and CO2 back to lungs
Describe platelets (thrombocytes).
platelets are little, tiny , immature cells that work along with clotting factors to form a blood clot
clot is cement, platelets are bricks
True or False
People with bleeding disorders need close watch on platelet count and clotting factor count.

What are the 2 categories of WBC?
Name 3 different granulocytes.
- most abundant of all WBC's
- very important phagocyte (engulfs and kills bugs)
- has to be summoned
- most commonly called PMN's or Poly's (polymorphynuclei)
- less than 1% of total WBC's
- good side
-- can function in inflamation
-- contain histamine that helps calm inflamation
- bad side
-- chronic inflamation (ie due to allergies) causes too many histamines released so need to take antihistamines
- important role in combatting parasitic & fungal infections
- elevated eosinophyls in blood are most likely caused by parasitic infection
-- example: pinworm
List 2 types of agranulocytes.
- largest WBC
- some are in lymphoctes, lymph nodes, blood stream
- are a macrophage -- play an important role in getting infection
-- get to infection first, if they can't get job done then neutrophyl comes later
Draw a picture showing how monocytes become macrophage.
the source of all specific immunity
Is the lymphatic system totally closed?
True or False
There are many places where the lymphatic system communicates directly with tissues.
syrum whose main function is to bathe tissues and wash away anything foreign (i.e. pollen, tar, bacteria) and move it to the lymph nodes
lymph node =
a collection point of WBC
major battles of immune system take place here
the condition of swollen, painful lymph nodes
results from lymph node swollen from WBC's fighting bacteria that is taken to it by lymph
name a condition that has lymphadenopathy
bubonic plague --> bubo = lymphadenopathy
How does lymph move in the lymphatic system?
lymph moves through muscle contractions
(lymph vessels have one way valves)
Name two examples of lymph nodes.
2. spleen is like a big lymph node
