Blood Cell Morphology Flashcards
How does the blood maintain homeostasis ?
- acting as a buffer
- participating in coagulation
- thermoregulation
What are the 3 main proteins that are part of the blood plasma ?
- albumins
- globulins
- fibrinogen
What cells are granulocyte leukocytes and what makes them granulocytes ?
- Neutrophils, eosinophils and basophils
- Cytoplasm packed with granules
- Nucleus has 2 or more lobes
What cells are agranulocyte leukocytes and what makes them agranulocytes?
- Lymphocytes and monocytes
- Cytoplasm have few or no granules
- Mononuclear
What is the quickest RBC to respond ? (For example whenever you get and inflammation or a bacterial infection)
Neutrophils (BOLT OF CELLS)
Neutrophils and eosinophils work on the basis of chemotaxis. What do this mean?
They can detect the chemical releases (cytokines) from e.g and infection or inflammation and they will trap the origin of that chemical release to the site
When they are at the site they are also phagocytic
What can the granules in eosinophils release and what is this important for ?
Histamine
Allergic response
What is the main role of eosinophils ?
Killing parasitic worms or parasitic infections
What WBC is bilobed ?
Eosinophils
What can the granules in basophils secrete and what are they needed for ?
Heparin (anti-coagulant)
Histamine (vasodilator) - allergic reaction
What type of nucleus do monocytes have?
Kidney / U-shaped
When monocytes migrate into the tissue, what do they differentiate into
Phagocytic Macrophages
Where is a kupffer cell?
A macrophage found in the liver
List the WBC in relative abundance.
Neutrophils Lymphocytes Monocytes Eosinophils Basophils
How are thrombocytes formed?
The megakaryocytes stick an arm into blood vessels in the bone marrow and the flow of blood breaks off fragments of the megakaryocyte
