what are the properties of blood cells.

Since this is not my area of expertise, I searched Google under the key words "blood cells" to get these possible sources:

http://www.fi.edu/biosci/blood/white.html
http://en.wikipedia.org/wiki/White_blood_cell
http://en.wikipedia.org/wiki/Red_blood_cell

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.
