Blood Plasma

What is average temperature of blood?

38 degrees Celsius (100.4 degrees Fahrenheit)

What are the three main groups of plasma proteins and their percentages?

Albumins (groups of proteins): 54%, Globulins (groups of proteins): 38%, and fibrinogen (a single type of protein): 7% Of note: albumins and globulins are transport proteins and fibrinogen is involved in clotting

How does blood provide protection?

Blood clotting, WBCs to protect against disease

What homeostatic variables are regulated by blood?

Body temperature, pH, osmotic pressure (water content of cells)

What percentage of blood plasma are other solutes?

1.5 to 2%

What percentage of blood plasma are proteins?

7% (these are the proteins only found in blood plasma)

Normal pH range

7.35 to 7.45

What percentage of plasma is water?

91.5%

Formed element

Erythrocytes, Leukocytes, and Platelets that make up 45% of whole blood

What is the single biggest factor affecting viscosity?

Hematocrit

Where are these plasma proteins synthesized?

Liver

Volume of blood in adults

Male: 5 to 6 liters Female: 4 to 5 liters

Osmolarity

Measure of total number of dissolved particles per liter of solution (amount of solute in a solution)

Substances transported by blood

Oxygen, carbon dioxide, nutrients, hormones, heat, and waste products; electrolytes such as potassium, calcium, sodium, magnesium, chloride

What is the single biggest effect of osmolarity of blood?

Plasma proteins

Plasma proteins

Proteins confined to blood; constitutes most of blood plasma that is not water or formed elements

Which non-protein solute in blood has a big effect on both water content and osmolarity?

Sodium which is most abundant solute after plasma proteins

Plasma

Straw-colored liquid that does not contain any formed elements which makes up 55% of whole blood
