Term
Characteristics of Blood
Definition
temp. 100.4 f ph:7.35-7.45 func. trans port nutrients/wastes through out the body comp. erythrocytes (red boold cells), leukocytes (white blood cells) thrombocytes (plateletes) and plasma (matrix)
Term
Blood comp
Definition
45% blood cells 55% plasma
Term
Erythrocytes
Definition
Characteristics red blood cells, biconcave disks, 1/3 is hemoglobin, mature erthrocytes discard their nuclei
Func carry o2
Term
oxyhemoglobin
Definition
when o2 combines w/ hemoglobin, bright red
Term
deoxyhemoglobin
Definition
when o2 is released from hemoglobin, dark red
Term
o2-carrying capacity
Definition
the# of erythrocytes is a ,measure of the bloods o2carrying capacity males have more erythrocyte per cubic millimeter
Term
Erythrocyte production
Definition
in embryo and fetus yolk sac liver and spleen, after red bone marrow through erythropoieses
Term
Erythrocite production
Definition
in embryo and fetus yolk sac liver and spleen, after red bone marrow through erythropoieses
Term
erythrocyte regulation
Definition
negative feed back system using the hormone released from the kidneys, erthropotientin; dietary factors vitamin b 12, iron and folic acid a deficiency in rbc or or hemoglobin results in in anemia
Term
Lifecycle of Erythrocyte Step 1
Definition
1. Nutrients from rood are absorbed in the intestine
Term
Lifecycle of Erythrocyte Step 2
Definition
2. Vitamin B12, folic acid, and iron are transported via blood to red bone marrow
Term
Lifecycle of Erythrocyte Step 3
Definition
3. Erythrocyte production occurs in the red bone marrow
Term
Lifecycle of Erythrocyte step 4
Definition
4. Erythrocyte mature, lose their nuclei, and circulated for about 120 days
Term
Lifecycle of Erythrocyte Step 5
Definition
5. With age, erythrocytes becomes fragile and damaged from passing through capillaries
Term
Lifecycle of Erythrocyte Step 6
Definition
6. Macrophages in the liver and spleen phagocytizes damaged erythrocytes
Term
Recycling and excretion of hemoglobin
Definition
globin (protein); heme (iron and biliverdin) iron is transported back to red bone marrow to be store and recycled, some of the biliverdin are converted in to bilirubin to be excreted in bile
Term
Leukocytes Characteristics
Definition
func. Fight against infections and diseases, inflamations; formed from hemocytoblasts; posses nuclei but do not contain hemoglobin; leukocyte count: 5,000-10,000 per cubic millimeterl; different white blood cell count lists % of the types of leukocytes
Term
Leukocytosis
Definition
excess leukocytes, signals infection;
Term
Leukopenia
Definition
deficiency in leukocyte
5 types of leukocytes distinguished by size, granular appearance of the cytoplasm and shape of nuclei
Term
Neutrophils
Definition
comprise of 54-62% fo the total leukocytes, multi-lobed nucleus
Term
Granulocytes
Definition
contain granuoles in the cytoplasm
Term
Eosinophils
Definition
comprise of 1-3% of total leukocytes, course granules that stain red, 1&1/2- 2x bigger than erythrocytes
Term
Basophils
Definition
comprise of less than 1% of total leukoctes, granules stain blue, 1&1/2-2x bigger than erythroctes
Term
Agranulocytes
Definition
can’t see granules
Term
Monocytes
Definition
3-9% of total leukocytes; largest blood cells; nuclei has variable sapes
Term
Lymphocytes
Definition
25-33% of total leukocytes; long lived; round nucleus with small rim of cytoplasm visible, approximately the same size as erythrocytes
Term
Diapedesis
Definition
the ability for leukocytes to leave circulation by squeezing through blood vessel walls to attack bacteria and clean debris
Term
Neutrophil
Definition
phagocytize small particles
Term
Monocyte
Definition
phagocytize larger particles (monocytes can become macrophages- fixed phagocytic cells in a paricular organ tissue)
Term
Eosinophil
Definition
moderate allergic reactions and defend against parasitic worm infections
Term
Basophil
Definition
release histamine to promote inflammation and release heparin to inhibit blood clotting
Term
Lymphocyte
Definition
immunity and produces antibodies
Term
Blood Plasma Character
Definition
clear, straw-colored fluid portion of blood,
Term
Blood Plasma Function
Definition
: transport nutrients and gasses, regulate fluid and electrolyte balance, maintain pH
Term
Components of Plasma; Gases
Definition
o2 and co2
Term
Components of Plasma; Nutrients
Definition
amino acids, monosacchrides, nucleotides, lipids
Term
Components of Plasma; Proteins; Albumins
Definition
helps maintain osmotice pressure of the blood
Term
Components of Plasma; Proteins; Globulins
Definition
alpha and beta globulins transport lipids and fat souluable vitamins, Gamma gobulins form antibodies
Term
Components of Plasma; Proteins; Fibrinogen
Definition
blood coagulation
Term
Components of Plasma; Lipoproteins; high-density
Definition
: high in protein, low in lipid
Term
Components of Plasma; Lipoprotein; Low-Density
Definition
: high in cholestrol, low in protein
Term
Components of Plasma; Lipoprotein; Very Low-Density
Definition
high in triglycerides
Term
Components of Plasma; Lipoprotein; Chylomicrons
Definition
very high in triglycerides
Term
Components of Plasma; Nitrogenous substances
Definition
urea and uric acid (products of protein and nucleic acid catabolism)
Term
Components of Plasma; Electrolytes
Definition
sodium, potassium, chloride, phosphate, bicarbonate, sulfate
Term
Thrombocytes
Definition
blood platelets from megakaryocytes normal count 130,000 to 360,000 platelets pre cubic mm3 function repair damaged blood vessels (clotting)
Term
Hemostasis
Definition
stoppage of bleeding not the same thing as clotting clotting is one step
Term
Hemostasis Step 1
Definition
Blood vessel spasm
Term
Hemostasis Step 2
Definition
Platelet plug formation
Term
Hemostasis Step 3
Definition
Blood coagulation (blood clotting)
Term
blood clotting; thromnoplastin
Definition

Term
blood clotting; prothrombin activator
Definition
to prothrombin
Term
blood clotting; prothrombin

Thrombus
Definition
abnormal clot does not move until it becomes an emolus
Term
emolus
Definition
dislodges thrombus so that it moves around
Term
Agglutination
Definition
= interaction of proteins on the surfaces of erythrocytes (antigens) with certain antibodies carried in the plasma, agglutination occurs when there is an incompatible transfusion of blood surface protein on a cell
