Chapter 8 Notes: Blood and Lymphatic System
Blood Function:
o __________________________________________________________________________________________ to body cells
o Carry ___________________________________________________, such as carbon dioxide, away from cells
Components of blood:o Plasma 55%o Various types of blood cells 45%
______________________________________________________
______________________________________________________
______________________________________________________
Plasma:o Yellowish, liquid portion of bloodo Contains electrolytes, vitamins, nutrients, hormones, clotting factors and antibodies
Platelets:o ________________________________________________
____________________________________________________ They bind/clot together in a process called _____________________________________ to seal a wound and
prevent a loss of blood.
Erythrocyte:
o ___________________________________________________o Transports oxygen and carbon dioxide in the bloodstream
Leukocyte:o ___________________________________________________
o Protects body from harmful substances called______________________________________
Anatomical terms and abbreviations associated with components of the blood:
o __________________________________________________________________________________ Compound in RBC’s that contains iron (Fe) to aid in the binding and transport of
oxygen and carbon dioxide (CO2) in the blood
o __________________________________________________________________________________ Percentage of packed RBC in the blood
Females: 40% Males: 45%
o __________________________________________________________________________________ Type of WBC that fights off infections by “swallowing” bacteria
Blood Disorders
___________________________________________________________________________________oReduction in the number of RBC in the body, or its ability to carry oxygen
____________________________________________________________________________________oType of leukemia in which cancerous cells replace healthy bone marrow cells
_____________________________________________________________________________________oBleeding disorder characterized by a decrease in platelet cells (and thus clotting factors)
Lymphatic System Function:
oProtects the body by ____________________________________________________________________________________ from the lymph
oHelps maintain body’s internal fluid environmentoCarries fats away from digestive system
Components of the lymphatic system:o Vessels o Glandso Ductso Capillaries
o _______________________
o _______________________
Lymph Structureso Spleen
Filters out __________________________________________________________________________ Removes cellular debris
o Nodes/glands Located in lymph vessels Contain a large amount of ___________________________ Depository for cellular debris and pathogens so that they can be phagocytized
o Thymus gland Changes lymphocytes to T-cells, which give you immunity to pathogens
Immunityo Process of __________________________________________________ induced by exposure to an antigen
___________________________________________: substance that, when introduced to the body, causes formation of antibodies against it
___________________________________________: substance produced by the body that binds and destroys antigens
Abbreviations associated with the Lymphatic System
o __________________________________________________________________________________________________ Antibodies that help protect the body from pathogens
o __________________________________________________________________________________________________ Caused by HIV (human immunodeficiency virus) HIV infects and destroys T-cells, preventing an immune response Referred to as AIDS during advanced stages of the disease
Diagnostic Tests and Procedures Associated with Blood and Lymphatic System
o ____________________________________________________________________________ Most common lab blood test performed to check the levels of RBC, WBC, HGB and HCT
o ____________________________________________________________________________ Test performed to find the average volume of a RBC If RBC is small it indicates the presence of anemia
o ____________________________________________________________________________ Test performed to find the average weight of hemoglobin in a RBC If hemoglobin weight is below normal it indicated presence of anemia
o ____________________________________________________________________________ Test performed to find the average amount of hemoglobin in each RBC If hemoglobin levels are low it indicates presences of anemia
o _____________________________________________________________________________ Test performed to determine the level of thrombocytes in the blood
o _____________________________________________________________________________ Test to measure the amount of inflammation in the body
o _____________________________________________________________________________ Test performed to determine coagulation defects such as platelet disorders
o _____________________________________________________________________________ Measures the activity of the clotting protein prothrombin Low prothrombin levels indicate a clotting disorder
o _____________________________________________________________________________ Full body x-ray used to detect tumors and cancers such as lymphoma
o _____________________________________________________________________________ Body scan used to measure the body’s response to radiation therapy
o _____________________________________________________________________________ Blood test performed to measure kidney function
o _____________________________________________________________________________ Blood test performed to measure liver function
o _____________________________________________________________________________ Blood test performed to measure liver function
