Filled with grains |
|
Name the two agranulocytes |
Lymphocytes and monocytes |
There's no grains in sight |
|
These phagocytic wbcs have 3 to 6 bulges or lobes on the nucleus and are the most numerous of all wbcs making up 50 to 70% of them |
Neutrophils |
|
|
This type of WBC with a nucleus that is bi-lobed, is non phagocytic and attacks large worms and parasites by gathering around the parasite and releasing destructive enzymes from their granules on to the parasite |
Eosinophils |
|
|
This rarest of all wbcs which makes up less than 1% of all wbcs has a nucleus that is u or s shaped. It's granules contain histamine which causes Vasodilation during inflammation |
Basophil |
|
|
This WBC accounts for about 25% of all wbcs, has around nucleus, very little cytoplasm with no granules, the T version of this fights viruses and cancer cells. The B version forms antibodies |
lymphocytes |
|
|
This type of WBC is the largest of all wbcs and has a kidney-shaped nucleus. It is referred to as a macrophage when it migrates out of the bloodstream. Are known for attacking viruses , intracellular parasites, and chronic infections such as TB |
