HELL3 Blood Worksheet Assignment - Chapter 3

Vocabulary flashcards detailing blood composition, serum production, electrolyte types, collection tube colors, and the stages of hemostasis based on the Chapter 3 laboratory worksheet.

Plasma

The liquid portion of blood that makes up roughly $55\%$ of an average blood sample.

Formed Elements

The cellular portion of blood, including erythrocytes, leukocytes, and thrombocytes, making up roughly $45\%$ of an average blood sample.

Water (in Plasma)

The primary component of plasma, making up roughly $90\%$ of its volume.

Erythrocytes

A type of formed element found in blood cells, also known as red blood cells.

Leukocytes

A type of formed element found in blood cells, also known as white blood cells.

Thrombocytes

A type of formed element found in blood cells, also known as platelets.

Serum

A straw-colored liquid derived from plasma that does not contain fibrinogen; it contains albumin, antigens, antibodies, and globulins.

Fibrinogen

A clotting protein found in plasma but absent in serum.

Electrolytes

Minerals found in plasma and serum, including chloride, bicarbonate, phosphate, magnesium, calcium, potassium, and sodium.

Plasma Collection Tubes

Tubes used for collection include light green, light blue, dark green, pink, royal blue, lavender, gray, tan, and yellow.

Serum Collection Tubes

Tubes used for collection include gold, SST, tiger, red, orange, and royal blue.

Hemostasis

The process of blood clotting, which occurs in four main phases.

Vasoconstriction

The first phase of hemostasis where blood vessels contract to reduce blood flow in the injured area.

Platelet Plug Formation

The second phase of hemostasis where platelets clump together to form a primary plug.

Coagulation

The third phase of hemostasis where fibrin forms a mesh to create a stable clot.

Fibrinolysis

The final phase of hemostasis where the blood clot is dissolved after the vessel has healed.

Clotting Disorders

Conditions where blood clots excessively or insufficiently, increasing the risk of hematoma, prolonged bleeding, or bruising during phlebotomy.
