Albumins primary functions?

Answer 6

• Maintains osmotic pressure BETWEEN BLOOD AND body tissue.
• Major transport carrier of
  other molecules

Question 7

Albumin deficiency can promote what?

Answer 7

• Edema, due to fluid retention in the interstitial space.

Question 8

Four types of globulin proteins

Answer 11

Alpha 1
Alpha 2
Beta 1
Immunoglobulins

Question 12

Fibrinogen

Answer 12

• Inactive form of fibrin
• clotting protein that stabilizes
  the platelet plug
• Protein with highest affinity
  for extracorporeal surfaces.

Question 13

Hypofibrinogenemia

Answer 13

100 mg/dl

Question 14

Hypoproteinemia

Answer 14

Decreased plasma protein
concentration due to:
– Malnutrition
- malabsorption
- excretion
- hemodilution
-  (cirrhosis)

Question 15

Hyperproteinemia

Answer 15

Increased plasma protein
concentration due to:
- Dehydration 
- Multiple Myeloma (production 
  of paraproteins)
- Hyperviscosity = clotting in 
  microvasculature.

Complement System

Answer 21

* is part of the innate
  immune reaction
* 25-30 inactive soluble 
  proteins.
* Vasoactive molecules that take a part in the inflammatory response.

Question 22

Complement function

Answer 22

• Antigen destruction

  tissue injury; Increase
  vascular permeability
• Immune protection until
  antibody can reach full force
  7-14 days.
• Opsonization
• Lysis

Question 28

Anaphyoltoxin:

Answer 28

Active components that
don’t end up stuck to a cell may have strong
inflammatory influence.
– C3a, C4a, C5a

Question 29

Membrane attack complex

Answer 29

- Group of 5 Complement
proteins (C5, C6, C7, C8,
