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)

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?
