WBC Flashcards
Functions of Blood (3)
- Transportation
- Defense
- Homeostasis
Diapedesis def
When leukocytes squeeze through cell walls in blood vessels.
Granular (3)
- Neutrophil
- Eosinophil
- Basophil
Granular (2)
Monocytes, Lymphocytes
Neutrophil Function
- Rapid response to infection
2. phagocytosis towards bacteria
Eosinohilis function
Phagocytic to antibody bound targets
Basophil function
Intensifies inflammatory response
Natural Killer Cells
Recognize non-self cells and cancer cells
B cells
produce antibodies that bind to foreign or abnormal plasma membranes
T cells
Physically attack foreign/diseased cells
Monocytes function
release defense and chemicals that attract other leukocytes
Leukopenia
abnormally low WBC count
Leukocytosis
abnormally high WBC count
Leukemia
Cancerous condition involving abnormal overproduction of leukocytes
lymphoma
malignant T or B cells collect in lymph-node, spleen, liver or other tissue
Platelets
Formed in bone marrow
critical growth and repair of tissue
Thrombocytosis
too many platelets
thrombocytopenia
low platelet number
thrombus
clot in unbroken vessel (blood clot can cause blockage in vessels)
Embolus
thrombus in blood stream
Hemophilia
lack of clotting factor (bad for injuries)
