Hematology Flashcards

Front

Hematology

Back

The study of the blood and blood-forming organs

Front

Plasma

Back

An extracellular and liquid portion of blood

Front

Formed elements

Back

The cellular components of blood, specifically red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes)

Front

Serum

Back

The clear liquid part of the blood that remains after blood cells and clotting proteins have been removed

Front

Hematocrit

Back

The volume percentage of red blood cells (RBCs) in a sample of whole blood

Front

Osmolarity

Back

The concentration of solutes in a solution, specifically the number of osmoles (molal concentration) per liter of solution

Front

Colloid osmotic pressure

Back

The pressure exerted by colloids (large molecules, primarily proteins like albumin) in a fluid, specifically blood plasma, that prevents water from leaving the bloodstream and encourages its return

Front

Albumin

Back

The most abundant circulating protein found in plasma

Front

Hemolysis

Back

The breakdown and destruction of red blood cells (RBCs), leading to the release of hemoglobin into the bloodstream

Front

Bile pigments

Back

Colored compounds, primarily bilirubin and biliverdin, produced as waste products from the breakdown of heme, particularly from red blood cells
