Blood


A post I did sometime back regarding the BO blood type was actually from this blood. However, what I didn't mention there was what the pathogen fighters in the blood streams were: white blood cells (Leukocytes or Leucocytes).




As seen in the video and the chart, there are actually a variety of white blood cells! For example, the white blood cell in the video with multiple spots surrounding it is seen as a basophil! Each white blood cell has different functions and appearances.

Five of the most important white blood cells and their functions are: 
1. Neutrophils: They are the most abundant and they use phagocytosis to destroy pathogens (engulfing of the pathogens).
2. Lymphocytes: Second most abundant and has B cells, which create antibodies that destroy pathogens targeting immune system cells, and T cells which aid in recognition of attacking germs.
3. Monocytes: Largest type of white blood cell and has receptors that detect chemical signals that indicate whether or not there is an infection or inflammation.
4. Eosinophils: 1-4% circulate in the bloodstream and are significant for fighting parasitic infections such as those that may cause malaria.
5. Basophils: Least common white blood cells that have surface receptors capable of binding a type of antibody responsible for allergic reactions,
