All the white blood cells are able to move like an amoeba, and can migrate out of blood vessels into the surrounding tissues. Note-it is easy to confuse the different leucocytes in blood smears. To identify them, you need to look for the shape of the nucleus, and compare their size, relative to that of a red blood cell.
peri-. a prefix meaning âabout,â âaroundâ (perimeter; periscope), âenclosing,â âsurroundingâ (pericardium), ânearâ (perigee; perihelion).
The ROOT-WORD is the Prefix PERI meaning AROUND. As usual, every word opens not only one door, but many doors. This one PERI is no exception. On your list are words useful in medicine, anatomy, geology, mathematics, dentistry, publications, and, of course, space science. In the last, especially, I have been helped by the words PERI & AROUND and APO & AWAY. I used to be confused be PERIgee and APOgee.
