Chapter 9 Flashcards
red blood cells
erythrocytes
Connective tissue composed of a liquid medium in which solid components are suspended
plasma
white blood cells
leukocytes
platelets
thrrombocytes
embryonic
blastic
The development of blood cells to their mature form
hematopoiesis
hemotopoiesis
red cell development
erythropoiesis
A specialized iron-containing compound that gives red blood cells their red color
hemoglobin (Hb, Hgb)
Protective protein produced by B lymphocytes in response to the presence of a foreign substance called an antigen
antibody (Ab)
Substance, recognized as harmful to the host, that stimulates formation of antibodies in an immunocompetent individual
antigen
Substance derived from the breakdown of hemoglobin and excreted by the liver
bile pigment
Chemical substance produced by certain cells that initiates, inhibits, increases, or decreases activity in other cells
cytokine
Ability to develop an immune response or recognize antigens and respond to them
immunocompetent
Specialized lymphocytes that kill abnormal cells by releasing chemicals that destroy the cell membrane, causing its intercellular fluids to leak out
natural killer (NK) cells
WBCs migrate through endothelial walls of capillaries and venules, and enter tissue spaces by a process called
diapedesis
red acidic dye
eosin
alkaline
basic
_______ contain granules that stain a pale lilac color
Neutrophils
_________ contain granules that stain red because of their affinity for the red acid dye eosin
Eosinophils
_______ contain granules that stain dark purple because of their affinity for the purple alkaline (basic) dye
Basophils
The main function of basophils is to release _______ and ________ at sites of injury
histamines
heparin
_______ arise in the bone marrow from stem cells but mature in lymph tissue.
Agranulocytes
Unlike granulocytes that typically have lobed nuclei, agranulocytes have nuclei that do not form lobes. They are called
mononuclear leukocytes (MNLs)
Lymphocytes include
B cells, T cells, and natural killer (NK) cells
