How much blood does a human have?

What is the compositon of Blood?
5 Liters

Cellular Elements suspended in fluid, Plasma
What percentage of blood volume is Plasma?
50% - 60%
What is Plasma?
A complex solution in which blood cells are suspended. It contains sodium, chloride, amino acids, oxygen, hormones, and vitamins.
What percentage of plasma is water?
How does the quality control in hematology differ from quality control in other lab departments?
Standards are not available, and is not possible with blood cells since it is a living tissue.
What is the only substance measured in Hematology?
Hemoglobin. The hematology lab must rely on commercial control solutions.
Define the following:


Excess of RBC also Polychthemia

Increase of WBC above normal

Abnormal increase in the number of platelets in the blood
What are the cellular elements of blood?
Erythrocytes - RBC

Leukocytes - WBC

Thrombocytes - Platelets
How long does Erythrocytes live?
120 days.
Conditions that cause hematological diseases are:
Anemia - RBC too low

Leukemia - WBC production out of control

Thrombocytopenia - Low platelet count
Describe inherited hematological diseases:
Hemophilia - Bleeding problems due to the bloods inability to clot; the coagulation factor is missing.

Sickle Cell Anemia - abnormal hemoglobin function causes by structure.
Compare accuracy and precision of manual and automated blood cell counting methods.
Manual Counts coefficient of 10%...Automated is 1-3%
Name the Five types of Leukocytes.
Never Let Monkeys Eat Bananas
Neutrophils 60%
Lymphocytes 30% Immunity
Monocytes 6%
Eosinophils 3% Allergy Attack
Basophils 1% Histamine
A type of white blood cell responsible for engulfing and digesting micro-organisms. Granulocytes consist of three types of phagocytic, or cell-eating, cells: basophils, eosinophils and neutrophils
A type of white blood cell; monocytes and lymphocytes are agranulocytes
Define Platelet
Platelets are irregularly-shaped, colorless bodies that are present in blood. Their sticky surface lets them, along with other substances, form clots to stop bleeding
What is the function of platelets?
When bleeding from a wound suddenly occurs, the platelets gather at the wound and attempt to block the blood flow. The mineral calcium, vitamin K, and a protein called fibrinogen help the platelets form a clot.
What does plasma contain?
The plasma contains salts and various kinds of proteins, hormones, Sodium Na+
Potassium K+
Calcium Ca
Chloride Cl-
Hydrogen Carbonate HCO3-
What is serum
The clear, thin and sticky fluid portion of the blood that remains after coagulation. Serum contains no blood cells, platelets or fibrinogen
Plasma contains?
Clotting agents such as fibrinogen
What color tube for Serum?

What color tube plasma
Red Top Tube

Light Blue/EDTA
What six things are in a CBC?
White blood cell (WBC) Incease means Bacterial, and decrease is viral.

White blood cell differential looks at the types of white blood cells present.
Red blood cell (RBC) count is a count of the actual number of red blood cells per volume of blood.

Hemoglobin measures the amount of oxygen-carrying protein in the blood.

Hematocrit measures the amount of space red blood cells take up in the blood.

The platelet count is the number of platelets in a given volume of blood. Both increases and decreases can point to abnormal conditions of excess bleeding or clotting

RBC Morphology = Anemai types
