Functions of Plasma proteins Flashcards
Which plasma protein maintains the colloid osmotic pressure in capillaries or blood vessels?
Albumin
Which plasma protein(s) contributes to blood viscosity?
Fibrinogen and globulins
Due ro their asymmetrical shape.
What is the significance of blood viscosity in circulation?
Helps maintain blood pressure by providing resistance to flow of blood in vessels.
Which plasma protein primarily plays a role in blood coagulation?
Fibrinogen
Also, prothrombin etc
Gamma globulins are primarily known for which function in the body?
Defense and immune system role. By producing antibodies against microorganisms
What percentage of buffering capacity is attributed to plasma proteins?
About 15%
Which cation that often binds proteins in the blood at normal PH?
Sodium
Give examples of transport plasma proteins and what they transport.
Hb.—— CO2 transport
Thyroxine—–transported by an alpha globulin called thyroxine binding protein.
Cortisol—-transported by transcortin….which is a mucoprotein.
Vitamin ADEK….transported by Lipoproteins.
What is the function of transcobalamin in the plasma?
Transport of Vitamin B12.
Bilirubin is transported by which plasma protein?
Albumin
Which plasma protein transports free HB in the plasma?
Haptoglobin
How is 50% calcium transported in the plasma?
It is bound to a plasma protein….albumin
What are the major functions of plasma proteins in plasma?
- They exert osmotic pressure
- They contribute to blood viscosity
- They play vital role in blood viscosity
- They are significant role in defense/immune mechanism of the body.
- They play a crucial role in maintaining the acid-base balance of the body.
- They play a significant role in transporting materials/substances in the plasma
- They also serves as protein reserves, which can be utilized by the body under certain conditions such as fasting, inadequate protein intake etc.
- Role in suspension stability of RBCs
- Fibrinolytic function
- Role in nourishing tissue cells.
What does “suspension stability” mean?
Ability of RBCs to remain uniformly suspended on the plasma(blood)
Which plasma proteins accelerate the plasma’ s ability for suspension stability of RBCs?
Globulins and Fibrinogen
Which two cells are necessary for tissue nourishment and how are they achieved?
Leukocytes uses plasma proteins to produce the substances.
They are
Trrphones or Carrel
