Unformatted text preview: Be able to estimate roughly how many erythrocytes, leukocytes, and platelets are in a mm 3 of blood. [Editor’s note: just be able to give a ballpark figure for normal blood – no biggie] Know the five categories of leukocytes. Be able to describe their functions, anatomic characteristics, and be able to rank them in terms of most abundant to least abundant. Know the clinical ramifications if a particular leukocyte category where to be elevated in the blood (e.g. – what might an elevated neutrophil count mean?). Where do leukocytes carry out their business – i.e. – do they do their work in the blood? Know what a CBC (complete blood count) and differential (differential blood count) are – and why they are useful clinically....
