Chapter 19 (Cardiovascular) Flashcards
The branch of science that diagnoses and treats the diseases of blood forming tissue.
Hematology
Maintaining osmolarity
Albumin
Carry gases to & from the lungs
Erythrocytes (red blood cells)
True Cell (Body’s Immunity)
Leukocytes (White Blood Cells)
What type of formed element releases enzymes for clotting?
Platelets (thrombocytes)
The percentage of total blood volume occupied by RBCs.
HTC (hematocrit)
Significant drop in HCT (hematocrit).
Anemia
Abnormally high RBCs, (hematocrit may be 65% or higher).
Polycythemia
What cell forms all RBCs and all WBCs except lymphocytes?
Myeloid Cells
What cell forms lymphocytes?
Lymphoid Cells
What stimulates the specialization of hemocytoblasts into RBCs? (Produced in kidneys)
Erythropoietin (EPO)
What stimulates the production of thrombocytes (platelets)? (produced in the liver)
Thrombopoietin (TPO)
What stimulates the development of leukocytes? CSF (colony stimulating factor), and interleukins are types.
Cytokines
What carries the pigment hemoglobin, that binds to oxygen, creating the red color of this “cell”?
RBCs
specialize into fixed or wondering horseshoe shaped nucleus largest WBC
Monocytes
2-5 lobes in nucleus (polymorphonuclear)
Neutrophils
2 lobes in nucleus-contract allergic reactions, # increase during parasitic worm infections
Eosinophils
Neutrophils and eosinophils are both…
Granular Leukocytes
What are the characteristics of a Leukocyte (WBCs)?
These are true cells and are nucleated, have organelles, but do not have hemoglobin.
Macrophages detect cells with…
leaky CM and pull them from circulation in the Liver, spleen, and marrow.
Respond to allergic reactions creating signs & symptoms
Basophils
Extends from the surface of all nucleated cells -determines self vs non-self
Major Histocompatibility Complex (MHC)
What is the process called when WBCs crawl into circulation, to the site of the infection
Emigration (diapedesis)
Movement response to a chemical
Chemotaxis
They are the first to the site of a bacterial infection
Neutrophils
These release histaminase to combat the effects of histamines, and are also effective against parasitic worms.
Eosinophils
Release heparin, histamine, and serotonin, intensify inflammation, and allergic reactions.
Basophils
spend most of their time in marrow and lymph nodes.
Lymphocytes
These arrive in large numbers and phagocytize foreign material.
Monocytes
What is a clot in an unbroken vessel called?
Thrombosis
Produced by the normal flora of the intestine
Vitamin K
Dissolution of a clot
FibrinoLYSIS
Produced by mast cells- works by blocking thrombin
Heparin
What is the system that consists of blood, the heart and vessels?
Cardiovascular System
What is the connective tissue that has a liquid matrix (plasma)?
Blood
