Blood -Characteristics & Properties

The chief difference between plasma and serum involves the

presence/absence of clotting proteins.

Blood is approximately ____ percent plasma by volume

37-54%

The average life-span of a red blood cell is about

4 months.

Hematocrit, which is measured as a percentage of whole blood, is _____ percent in men, while it is only 42% in women.

46%

Plasma proteins that are necessary for blood to maintain osmotic pressure are

Albumins.

is a condition in which the oxygen-carrying capacity of RBCS is reduced.

Anemia

The function of hemoglobin is to

Bind and transport Oxygen and Carbon dioxide

Anemia, resulting in decreased oxygen-carrying capacity, is caused by

Both hematocrit and hemoglobin.

During their formation, RBCS

Eject their nucleus and most of their organelles.

Release

The process of blood clotting is an example of which function of blood?
