Blood Flashcards
(52 cards)
blood is a specialized type of connective tissue consisting of formed elements
or cells suspended in a circulating fluid known as
plasma
Plasma consists of plasma
proteins like fibrinogens, globulins, and albumins, and a ground substance called ___
serum
These are anucleate, biconcave, discoid cells filled w/ a reddish protein known as haemoglobin that transports oxygen and carbon dioxide
red blood cells
Reddish protein
haemoglobin
These are loosely related category of all cell types dedicated to protecting their host from infection and injury
- white blood cells
White blood cells are also known as
- leukocytes
WBCs are transported in the blood from their source, usually ______ or _____, to their tissue or body cavity destination
- bone marrow; lymphoid tissue
They are called segmenters bcs of their multi lobed nuclei connected by thin chromatin filaments
- neutrophils
Neutrophils are called _____ bcs of their multi lobed nuclei connected by thin chromatin filaments
- segmenters
Platelet cells comes from the cytoplasm of megakaryocyte thru the process known as
- thrombopoiesis
the dissolved components are mostly plasma proteins, but they also include nutrients, respiratory gases, nitrogenous waste products, hormones, and inorganic ions, collectively known as
- electrolytes
the most abundant plasma protein, is made in the liver and serves primarily to maintain the osmotic pressure of blood
Albumin
made by the liver and other cells, include transferrin and other transport factors; fibronectin; prothrombin and other coagulation factors; lipoproteins and other proteins entering blood from tissue
⍺-Globulins and β-Globulins
which are immunoglobulins (antibodies) secreted by plasma cells in many locations
ɣ-Globulins
the larges plasma protein, also made in the liver, which, during clotting polymerize as insoluble, cross-linked fibers of fibrin that block blood loss from small vessels
Fibrinogen
a system of factors important in inflammation and destruction of microorganisms
Complement proteins
Many blood stains are available, but _____ and ____ stains are superior for differentiating blood cell types with oil immersion objective lens.
- Giemsa; Wright
In stained blood films, erythrocytes are typically______, and nuclei of leukocytes, with an affinity for basic dyes, stain ____
- orange-red to pink; blue
They function only within the bloodstream to bind oxygen for delivery to the tissues and, in exchange, bind carbon dioxide for removal from the tissues.
Erythrocytes
The life span of erythrocytes is approximately
- 120 days
In blood smears, erythrocytes are usually 7 to 8 um in diameter. Since their size is relatively consistent in fixed tissues, they can be used to estimate the size of other cells and structures in tissue sections; in this role, erythrocytes are appropriately termed as “______.”
histologic ruler
______ are extremely deformable. They pass easily through the narrowest capillaries by folding over on themselves. They stain uniformly with eosin
Erythrocytes
The shape of the erythrocyte is maintained by a specialized _____ that provides the mechanical stability and flexibility important to withstand forces experienced during circulation
Cytoskeleton
______ represent most of the proteins in the lipid bilayer.
Integral membrane proteins
