Test 2 Chapter 10 Flashcards
Achlorhydria
absence of hydrochloric acid in the gastric secretions. Associated with thiamine deficiency in the setting of bacterial overgrowth
Agglutination
the process that occurs if an antigen is mixed with its corresponding antibody
Ataxia
poor muscle control that causes clumsy voluntary movements.
Arteriosclerosis
the thickening and hardening of the walls of the arteries, occurring typically in old age.
Atherosclerosis
the buildup of fats, cholesterol and other substances in and on the artery walls.
Deoxyhemoglobin
The form of hemoglobin without oxygen, the predominant protein in red blood cells.
Diapedesis
the passage of blood cells through the intact walls of the capillaries, typically accompanying inflammation.
Dyscrasia
an abnormal or disordered state of the body or of a bodily part.
Dyspnea
difficult or labored breathing.
Ecchymoses
a discoloration of the skin resulting from bleeding underneath, typically caused by bruising.
Endarterectomy
a surgical procedure in which a doctor removes fatty deposits blocking one of the two carotid arteries
Erythrocytosis
having too many red blood cells (a solid part) in relation to plasma (the liquid part)
Erythropoietin
a hormone that is produced predominantly by specialized cells called interstitial cells in the kidney. Once it is made, it acts on red blood cells to protect them against destruction. At the same time it stimulates stem cells of the bone marrow to increase the production of red blood cells
Ferritin
a blood protein that contains iron
Gastrectomy
surgery to remove all or part of the stomach
Glossitis
a condition in which your tongue becomes inflamed and swollen
Hemarthrosis
Bleeding into a joint
Hematocrit
the percentage by volume of red cells in your blood
Hemolysis
destruction of red blood cells.
Hemosiderin
a form of storage iron derived chiefly from the breakdown of erythrocytes
Hemostasis
the stopping of a flow of blood.
Hemoptisis
the spitting of blood derived from the lungs or bronchial tubes as a result of pulmonary or bronchial hemorrhage
Hepatomegaly
abnormal enlargement of the liver.
Hypochromic
the red blood cells have less color than normal when examined under a microscope
Interleukin
One of a group of related proteins made by leukocytes (white blood cells) and other cells in the body
Leukocytosis
an increase in the number of white cells in the blood, especially during an infection.
Leukopenia
a condition where the body doesn’t have enough disease-fighting leukocytes in the blood
Leukopoiesis
Leukopoiesis is a form of hematopoiesis in which white blood cells are formed in bone marrow
Macrocytes
Macrocytes are enlarged RBCs
Macrophages
a large phagocytic cell found in stationary form in the tissues or as a mobile white blood cell, especially at sites of infection.
Malabsorption
difficulty in the digestion or absorption of nutrients from food.
Megaloblasts
large nucleated red blood cell precursors with noncondensed chromatin. The most common causes of megaloblastic, macrocytic anemia are deficiency or defective utilization of vitamin B12 or folate.
Microcytic
a descriptive term for red blood cell (RBC) size smaller than the normal range.
Myelodysplastic
A group of disorders caused when something disrupts the production of blood cells.
Myelotoxins
destructive to bone marrow or any of its elements.
Neutropenia
occurs when you have too few neutrophils
Oxyhemoglobin
a bright red substance formed by the combination of hemoglobin with oxygen, present in oxygenated blood.
Pancytopenia
A condition in which there is a lower-than-normal number of red and white blood cells and platelets in the blood
Phlebothrombosis
an inflammatory process that causes a blood clot to form and block one or more veins, usually in the legs
Pleuthoric
excessively full of bodily fluid, particularly blood.
Reticulocyte
red blood cells that are still developing
Splenomegaly
an enlargement of the spleen
Stomatitis
inflammation and redness of the oral mucosa that can lead to pain and difficulty talking, eating, and sleeping
Syncope
a loss of consciousness for a short period of time
Thrombocytopenia
a condition in which you have a low blood platelet count
Thrombophlebitis
an inflammatory process that causes a blood clot to form and block one or more veins, usually in the legs
Varicosities
twisted, enlarged veins
