Blood Chap 10 Anaphy

Vocabulary flashcards for reviewing blood components and functions.

Plasma

Pale yellow fluid consisting of about 91% water, 7% proteins, and 2% other solutes.

Formed Elements

Includes red blood cells, white blood cells, and platelets.

Red Blood Cells

Biconcave disks that transport oxygen and carbon dioxide; contain hemoglobin.

White Blood Cells

Spherical cells that protect the body against invading microorganisms and remove dead cells.

Platelets

Cell fragments that play an important role in preventing blood loss.

Hematopoiesis

The process that produces formed elements of blood, derived from stem cells.

Hemoglobin

The protein responsible for the red color of red blood cells; transports oxygen.

Granulocytes

White blood cells containing large cytoplasmic granules (neutrophils, basophils, eosinophils).

Agranulocytes

White blood cells with very small granules not easily seen with a light microscope (lymphocytes, monocytes).

Neutrophils

Most common type of white blood cell; phagocytizes microorganisms.

Basophils

Least common white blood cell; releases histamine and heparin.

Eosinophils

Involved in inflammatory responses associated with allergies and asthma; attacks worm parasites.

Lymphocytes

Smallest of the white blood cells; produce antibodies and regulate the immune system.

Monocytes

Largest of the white blood cells; become macrophages and phagocytize debris in tissues.

Megakaryocytes

Large cells in the red bone marrow that produce platelets.

Vascular Spasm

Immediate constriction of a blood vessel to minimize blood loss.

Platelet Plug Formation

Platelets adhere to the damaged vessel and to each other to reduce blood loss.

Blood Clotting

A complex series of chemical reactions resulting in the conversion of fibrinogen to fibrin.

Agglutination

Clumping of red blood cells due to antibody-antigen interactions.

Hemolysis

Destruction of red blood cells.

Erythropoietin

Hormone released by the kidneys that stimulates red blood cell production.
