Define blood.
|
A connective tissue made up of a fluid matrix called plasma, and cells called formed elements.
|
|
What are the three types of formed elements?
|
Erythrocytes(RBCs), Leukocytes(WBCs), Platelets.
|
|
What is Erythrocyte's unique shape, its function and shape of nucleus?
|
Shape: Biconcave disc, anucleate.
Fxn: Transports hb that binds O2 and CO2. |
|
What is Platelet's unique shape, its function and shape of nucleus?
|
Shape: Oval biconvex disc, anucleate.
Fxn in homeostasis: it promotes blood clotting. |
|
How is leukocyte generally categorized as?
|
Granulocytes and Agranulocytes
|
|
What are the types of granulocytes?
|
Neutrophil, Eosinophil, Basophil
|
|
What are the types of agranulocytes?
|
Monocytes, Lymphocyte
|
|
Explain Neutrophil's shape, function and shape of nucleus.
|
Cytoplasm: pale, finely granular, evenly dispersed
Nucleus: segmented, 3-5 lobes fxn: Phagocytosis |
|
Explain Eosinophill's shape, function and shape of nucleus.
|
Cytoplasm: large homogeneous red granules
Nucleus: bilobed, densely stained fxn: Phagocytosis |
|
Explain Basophil's shape, function and shape of nucleus.
|
Cytoplasm: large blue specific granules, therefore, often obscure nucleus
Nucleus: bilobed or segmented |
|
Explain Monocytel's shape, function and shape of nucleus.
|
Cytoplasm: Agranular, pale blue cytoplasm with lysosomes
Nucleus: Kidney shaped, lightly stained fxn: Motile, macrophages |
|
Explain Lymphocyte's shape, function and shape of nucleus.
|
Cytoplasm: Agranular, faintly basophilic
Nucleus: Small, round, darkly stained |
|
How were two types of Leukocytes named?
|
It comes from their appearance after staining. granular leukocytes have abundant stained granules.
|
|
Define leukocytosis.
|
Excessive numbers of WBCs.
|
|
Define Keukemia.
|
Inadequate numbers of WBCs.
|
|
Define Leukopenia.
|
Inadequate numbers of WBCs.
|
|
Define Leukemia.
|
Over production of immature and abnormal WBCs.
|
|
Define polycythemia.
|
Abnormal increase in blood cells (HBCs) due to excess production of the cells by the bone marrow.
