Need help on my biology homework.
Hi, Ryan :)
This is a very common question in both Biology and Immunology!
The bottom line is this:
ALL White Blood Cells (WBCs) are knows as LEUOKOCYTES. (P.S> Essentially "cytes" just means "cells" )
There are two different branches of LEUOKOCYTES (again, WBCs)
The first ones are GRANULOCYTES~ as their name implies, they have GRANULES in their cytoplasm when they are stained :
These are :
- BASOPHILS ` low amount , usually for inflammation
- EOSINOPHILS ` low amount , usually parasite infections
- NEUTROPHILS ` MOST ABUNDANT, FIRST RESPONSE to INFECTION or INFLAMMATION (also called PMNs..or polymorphonuclear lymphocytes!)
These are all a part of our INNATE (or INSTINCTIVE ) immunity...this means it happens right off, doesn't last long and is the first line of defense!
The second branch is the AGRANULOCYTES...you guessed it! NO GRANULES in their cytoplasm when stained!
Two primary groups:
- Lymphocytes ` these are the T cells and B cells (T cells are attack cells, B cells produce antibodies to infections!) These are part of our ADAPTIVE IMMUNITY..this means that our body adapts to the foreign materials, or pathogens, and finds a way to get rid of them. (It also gives us immunity)
- Monocytes.. the second AGRANULOCYTE, .can become activated Macrophages, which EAT and destroy the pathogens! This is part of the INNATE immunity. These are REALLY big..I tell students to call them the "MAC ATTACK"
This may be more than you needed, but good luck!
