Ch.29 Alterations of Erythrocyte, Platelet, and Hemostatic Function

These flashcards cover key terms related to anemia, erythrocyte function, platelet disorders, and hemostatic mechanisms, facilitating a review of essential concepts.

Anemia

A condition characterized by a deficiency in red blood cells or hemoglobin, leading to decreased oxygen transport in the body.

Erythropoiesis

The process by which new red blood cells (RBCs) are produced from precursor cells in the bone marrow.

Hypersplenism

A condition where the spleen is overactive, resulting in the premature destruction of blood cells.

Microcytic Hypochromic Anemia

A type of anemia characterized by abnormally small red blood cells that contain insufficient hemoglobin.

Megaloblastic Anemias

Anemias resulting from impaired DNA synthesis, leading to larger than normal red blood cells.

Pernicious Anemia

A type of macrocytic anemia caused by a deficiency of intrinsic factor, which is necessary for vitamin B12 absorption.

Thrombocytopenia

A condition characterized by a low platelet count, increasing the risk of bleeding.

Disseminated Intravascular Coagulation (DIC)

A complex disorder that involves the simultaneous occurrence of clotting and bleeding.

Thromboembolism

A condition where a blood clot (thrombus) forms and then travels to block blood flow in a distant site.

Virchow's Triad

A clinical model that describes the three factors that contribute to thrombosis: endothelial injury, stasis of blood flow, and hypercoagulability.
