Chap 11 Blood Flashcards
What are the three main types of “formed elements” of blood?
Red blood cells or erythrocytesWhite blood cells or leukocytes Platelets or thrombocytes
What are the subtypes of white blood cells or leukocytes?
Granular leukocytes - neutrophils, eosinophils, and basophilsNongranular - lymphocytes and monocytes
What is the difference between blood plasma and blood serum?
Plasma is the liquid (extracellular) part of blood.Serum is plasma minus it’s clotting factors, still contains antibodies.
What protein in blood cells carries oxygen?
Hemoglobin
Can you give a broad definition of anemia?
Deficient number of red blood cells or deficient hemoglobin.
In general, what function do the WBC’s perform?
They defend the body from cancer cells that firm inside our tissues and from micro organisms that have succeeded in invading our body.
What is the role of fibrin in blood clotting?
Fibrin looks like a tangle of fine threads with RBCs caught in the tangle. This mesh work is the blood clot that forms a more long-term seal of the damaged blood vessel. The clotting mechanism contains clues for ways to stop bleeding by speeding up blood clotting.
What is the antigen in blood typing?
An antigen is a substance that can activate the immune system to make certain responses, including the production of antibodies.
What is meant when a person’s blood is described as “Rh negative”?
The Rh antigen is not present on their red cells.
Oxygen and Carbon Dioxide transport
Erythrocyte
Immune defense (phagocytosis)
Neutrophil
Defense against parasites
Eosinophil
Inflammatory response
Basophil
Antibody production
B lymphocyte
Cellular immune response; destroys virally infected cells and cancer cells
T lymphocyte
Immune defenses (phagocytosis)
Monocyte
Blood clotting
Platelet
Anti-bodies causing antigens to clump or stick together
Agglutinate
One of several types of proteins normally found in blood plasma;help stick in the blood
Albumin
Deficient number of red blood cells or deficient hemoglobin
Anemia
Substance produced by the body that destroys or inactivates a specific substance (antigen) that has entered the body
Anti-body
Blood disorder characterized by low red blood cell count; caused by destruction of myeloid tissue in the bone marrow
Aplastic anemia
White blood cell that stains readily with basic dyes
Basophil
Thin layer of white blood cells (WBCs) and platelets located between red blood cells (RBCs) and plasma in a centrifuged sample of blood
Buffy coat
The compound formed by the union of carbon dioxide with hemoglobin
Carbaminohemoglobin
Proportion of each type of WBC reported as a percentage of the total WBC count
Differential WBC count
