Anemia is most simply characterized by reduced numbers of erythrocytes and/or decreased erythrocyte hemoglobin content.
Hematopoiesis is the production of new blood cells such as white blood cells (WBC), red blood cells (RBC) and platelets. Although in utero a number of organs are hematopoietically active, including the liver and the spleen, from birth onwards hematopoiesis is centered almost exclusively in the bone marrow.
Normal body temperature in the dog and cat ranges from approximately 100 F to 103 F. Not all animals that have a temperature above this range, however, necessarily have a fever.
Immune-mediated thrombocytopenia (IMT) is a relatively common cause of bleeding in small animals, particularly the dog. Many differing disease processes may initiate IMT.
Albumin is the major determinant of oncotic or colloidal osmotic pressure, the force that holds fluids within the vascular compartment. Most of the important osmotically-active particles in the bloodstream (such as sodium, urea and glucose) are relatively small, and pass freely between the vascular and interstitial compartments, the bodys two major extracellular fluid compartments.
The most common immune-mediated blood disorders in small animal patients are immune-mediated thrombocytopenia (IMT) and immune-mediated hemolytic anemia (IMHA).
