Plasma Proteins Flashcards
leukocytes =
white blood cells
erythrocyes =
red blood cells
fx of erythrocytes
oxygen and CO2 transport and H+ binding
fx of leukocytes (2)
1) phagocytosis and killing of microbes
2) cellular and humoral immunity
4 functions of plasma
1) transport of nutrients
2) transport of by-products and waste
3) transportation of cells
4) maintain homeostasis (pH, temp, etc.)
fx of platelets
hemostasis. Inflammation to a lesser extent. Have filopodia when activated
Which animals normally have colorless plasma?
dogs, cats, pigs and sheep
Which animals have the highest percentage blood volume as a percent of body weight? Lowest?
Highest –> “hot-blood horses”, animals with large spleens, very young animals
Lowest –> pigs (due to large fat content)Col
Which animals normally have straw-colored plasma? Why?
Horses and cattle. Bilirubin and carotenoids cause color change
What can happen to plasma appearance postprandial?
Become lipemic
Plasma vs. serum
Plasma –> fluid in which blood cells circulate
Serum –> fluid obtained following centrifugation if blood is collected without anticoagulant and allowed to clot
Plasma protein concentrations higher or lower at birth?
lower
Total dissolved solids present in solution is proportional to?
The bending (refraction) of light as it passes through the sample
2 main classes of plasma proteins
1) albumin
2) globulins (all others that are not albumin)
What cell has lowest concentration on blood?
white blood cells (except for dog
Order platelets, RBCs and WBCs by order of greatest number in blood
RBCs > # platelets > # WBCs
Most common plasma protein
albumin
3 types of globulins
alpha, beta, gamma
Most common type of white blood cell in blood?
neutrophils
Which blood cells are nucleated in mammals?
white blood cells only
Which blood cells are nucleated in non-mammals?
All blood cells (including RBCs, WBCs, platelets)
About what percentage of blood is plasma?
55%
Specific protein components of serum
Albumin, globulins
Specific protein components of plasma
Albumin, globulins, fibrinogen
