Blood Study Guide Flashcards
What is the percentage range of Neutrophils in the blood?
50-70%
Neutrophils are the most abundant type of white blood cells.
Describe Neutrophils.
A type of granulocyte with multi-lobed nuclei; light, violet-colored cytosol with granules that do not take up either the acidic or basic stain; heavily involved in the phagocytosis of bacteria.
Neutrophils play a critical role in the immune response.
What is the percentage range of Eosinophils in the blood?
2-4%
Eosinophils are less common compared to Neutrophils.
Describe Eosinophils.
bilobed nuclei and red-stained granules that are involved in allergy responses and fighting parasitic infections.
Eosinophils are important in combating multicellular parasites.
What is the percentage of Basophils in the blood?
1%
Basophils are the least common type of granulocyte.
Describe Basophils.
bilobed nuclei and dark purple-stained granules that are involved in mediating inflammation.
Basophils release histamine and play a role in allergic reactions.
What is the physical description of a lymphocyte?
Large spherical nuclei, light blue-purple
Lymphocytes are a type of white blood cell involved in the immune response.
What percentage of leukocytes do lymphocytes comprise?
20-25%
Lymphocytes play a critical role in the immune system by producing antibodies and fighting cancer.
What is the primary function of lymphocytes?
Produce antibodies, fights cancer
Lymphocytes are essential for adaptive immunity.
What is the physical description of a monocyte?
Horseshoe-shaped, light blue or light purple
Monocytes are a type of white blood cell that can differentiate into macrophages.
What percentage of leukocytes do monocytes comprise?
3-8%
Monocytes are crucial for the immune response and can mature into macrophages.
What is the primary function of monocytes?
Matures into macrophages for phagocytosis
They are important for engulfing and digesting cellular debris and pathogens.
What is the physical description of a platelet?
Lack nuclei, colorless
Platelets are cell fragments involved in hemostasis.
What percentage of leukocytes do platelets comprise?
Less than 1%
Platelets are essential for blood clotting and wound healing.
What is the primary function of platelets?
Involved in clotting
They help prevent bleeding by forming clots at injury sites.
