- formed elements : these blood cells account for 45% of blood volume.
- water : plasma contains 90-92% of this.

- erythrocytes : normally, in whole blood, there are 4-6 million of these cells that are made in the red bone marrow.
- hemoglobin : in every rbc, there are about 200 million of these quaternary proteins that contain 4 globular proteins + 4 heme molecules (with iron).
- oxygen : one hemoglobin molecule carries four of these molecules.
- reduced : this is what hemoglobin becomes when its globular portion binds to h+ions.
- nucleus : rbcs lack this, and only have a 120-day life span.
- leukocytes : these disease-fighting cells have irregularly-shaped nuclei & are fewer in number than rbcs, with 5000-10,000 cells per mm3.

- prothrombin : this inactive enzyme is a blood protein (globulin) produced by the liver and is activated by thromboplastin.
- thrombin : prothrombin is converted to this active enzyme by the enzyme thromboplastin and ca2+.
- fibrinogen : this inactive enzyme is a blood protein (globulin) produced by the liver and is activated by thrombin.
- fibrin : the enzyme thrombin catalyzes the reaction that converts fibrinogen into this insoluble protein made up of sticky, thin threads.
