11. Blood Flashcards
Review
A type of connective tissue that consists of a liquid matrix
Blood
Functions of Blood
- Transport of gases, nutrients, and waste products.
- Transport of processed molecules.
- Transport of regulatory molecules.
- Regulation of pH and Osmosis
- Maintenance of body temp
- Protection against foreign substances
- Clot formation
Blood makes up __percent of our body weight
8%
The 8 percent is consist of 55% ___ and 45% ___
Plasma
Formed Elements
This is a pale yellow fluid that consist of about 91% water, 7% protein, and 2% others.
Plasma
This includes rbc, wbc, and platelets.
Formed Elements
This is the continuous process that produces formed elements. “Blood making”
Hematopoiesis
This is where all formed elements are derived
Stem Cells
Disk-shaped cells having thicker edges than the center.
RBC
Characteristics of RBC
- Biconcave Disk
- No nucleus
- Contains Hemoglobin
Transport O2 and CO2 from the lungs to the various tissues in the body.
Functions of RBC
Functions of RBC
- O2 enters RBC and bins to hemoglobin.
- Hemoglobin picks up O2 in the lungs and releases O2 in other tissues.
- CO2 is produced in tissues and transported in the blood to the lungs.
Spherical cells with a nucleus but lacks hemoglobin.
WBC
Larger than rbc and travel through ameboid movement.
WBC
Leukocytes
WBC
Functions of WBCs
- Protect the body against invading microorganisms and other pathogens.
- Remove dead cells and debris from the tissues by phagocytosis.
Types of WBCs
- Granulocytes
- Agranulocytes
Contains large cytoplasmic granules
Granulocytes
3 types of Granulocytes
- Neutrophil
- Basophil
- Eosinophil
Granulocyte:
A. Phagocytize microorganisms
B. Participates in inflammatory response.
C. Releases histamine and heparin
A. Neutrophil
B. Eosinophil
C. Basophil
2 types of Agranulocytes
- Lymphocyte
- Monocyte
This agranulocyte forms a ring around the nucleus.
- Lymphocyte
Becomes macrophages.
Monocyte
*Also called as Thrombocytes
*Produced from megakaryocytes
Platelets
3 Things to prevent blood loss
- Vascular Spasm
- Platelet Plug Formation
- Blood Clotting
Functions of Platelets
- Forms platelet plugs.
- Releases chemicals necessary for blood clotting.
Immediate but temporary constriction of a blood vessel.
Vascular Spasms
Platelet Plug Formation
Can seal up a small break
Formation of Platelet Plug
- Platelet Adhesion
- Platelet Release Reaction
- Platelet Aggression
Also called as coagulation
Blood Clotting
This is a network of threadlike protein fibers called fibron
Clot
Prevent clotting factors from forming clots under normal conditions.
Anticoagulations
Process wherein clot begins to condense
Clot Retraction
Process where clot is Dissolved
Fibrinolysis
Transfer of blood from one individual to another
Transfusion
Introduction of a fluid other than blood
Infusion
Clumping or rupture of blood cells and clotting within blood vessels
Transfusion Reaction
Molecules on the surface of rbc
Antigens
Proteins present in the plasma blood
Antibodies
Clumping of the cellz
Agglutination
Rupture of the rbc
Hemolysis
Used to categorize human blood
ABO Blood Group
An analysis of blood that provides information such as RBC count, WBC, count, hemoglobin, and hematocrit
CBC - Complete Blood Count
Reduced number of rbc or hemoglobin
Anemia
Lower than normal wbc
Leukopenia
Abnormally high WBC
Leukocytosis
Cancer of the red marrow
Leukemia
Prevents excessive bleeding when vessel is injured.
Clotting
