What is an immature blood cell called? |
Reticulocyte |
|
|
Charged with delivering oxygen and removing carbon dioxide would be a...? |
Erythrocyte |
|
|
Most abundant of the white blood cells |
Neutrophil |
|
|
Involved when you have an allergic reaction |
Eosinophil |
|
|
Produces fragments that form platelets |
Megakaryocyte |
|
|
Responsible for long term immunity |
Lymphocyte |
|
|
Classification of white blood cell that includes lymphocytes and monocytes |
Granulocyte |
|
|
Which cell secretes heparin which prevents clotting |
Basophil |
|
|
A phagocytic cell that migrates into the tissue |
Monocyte |
|
|
Which component of blood plasma plays a role in blood clotting that regulates fluid volume |
Proteins (albumin helps move fluid out of tissues and cells in patients that can be given too much fluid) |
|
|
Two types of hematopoietic tissue found in the body are located where? |
Red bone marrow & lymphatic tissue |
|
|
An immature erythrocyte is called a |
Reticulocyte |
|
|
In an adult, where can red bone marrow be found? |
Ends of long bones& flat and irregular bones (modular cavity in children) |
|
|
The stimulus for the production of new red blood cells is what? |
Decreased oxygen- oxygen levels decline, kills some red blood cells, those dead red blood cells are moved from circulation. This triggers the process of new red blood cell production |
|
|
What is Erythropoietin (EPO) and how is it secreted? |
EPO is a hormone secreted by the kidneys when oxygen levels start to decline to stimulate production of new red blood cells |
|
|
An increased number of Reticulocyte in lab work could be the result of what? |
A move to a higher altitude |
|
|
What is the normal life span of a red blood cell? |
120 days |
|
|
During hemoglobin recycling, hem is initially broken down into what? |
Iron and bilirubin |
|
|
During hemoglobin recycling, the iron portion is?... |
Is transported to the bone marrow and is used to create new hemoglobin- iron is not used in an production of new proteins |
|
|
What is the most numerous form element in the blood |
Red blood cells |
|
|
A patients lab results comes back and shows a high number of eosinophils, what could be happening? |
Allergic reaction |
|
|
What is the first stage of hemostasis (healing)? |
Spasm of the blood vessel |
|
|
What causes platelets to become sticky platelets? |
Collagen fibers |
|
|
The extrinsic clotting pathway is triggered when what happens? |
The damage to the vessel and surrounding tissue releases clotting factor |
|
|
What is the role of prothrombin activator in the clotting process? |
Prothrombin--> thrombin--> fibrinogen--> fine threads of fiber |
|
|
What is the final step before a blood clot forms? |
Final step in a blood clot forming is thrombin transforms fibrinogen into fine threads of insoluble fibrin, fibrin threads then form a Web at the site of injury in which passing blood cells become entraped |
|
|
Which vitamin is necessary for synthesis of clotting? |
Vitamin K |
|
|
A person had ABO blood type, what does that mean? |
The ABO system identify a type of antigen on the red blood cell |
|
|
A person with O blood |
A type O blood has neither A or Brad antigen and both anti A & B antibodies |
|
|
Which of the following statements about RH- (negative) blood is true RH |
RH negative blood lacks the RH antigen |
|
|
Clear extracellular matrix is called what |
Plasma |
|
|
If blood is spun out it turns into what? |
Plasma, Buffy coat, formed elements (red blood cells) |
|
|
The percentage of red blood cells in a sample of blood is called the what? |
Hematocrit |
|
|
What term is used to discuss thickness and stickiness of blood |
Viscosity |
|
|
The production of blood is called what? |
Hematophoesis |
|
|
All blood cells can trace their beginnings to a specific type of bone marrow cell called a..? |
Stem cell |
|
|
The red pigment filling the interior part of the red blood cell is called what? |
Hemoglobin |
|
|
On hemoglobin a molecule a molecule can bind with it, what molecule is that? |
Oxygen (4) |
|
|
The fewest of the formed elements in the blood are what? |
White blood cells, leukocytes |
|
|
The process of clot dissolving is called what? |
Fibrinolysis |
|
|
Each red blood cell carries a protein called a...? |
Antigen |
