Q

Name the three type of granulocytes

A

Neutrophils- are about twice the size of red blood cells and have nuclei with many lobes. They are most numerous type of white blood cell in a healthy individual 2) eosinophils - are about the same size as neutrophil. Their granule Stan orange/pink because they take up the red stain eosin. They have bi lobed nuclei. (3). Basophils - are smaller than the other two their granules take up a very dark blue basic stain

Q

Describe lymphocytes

A

Are about the same size as basophils but lymphocytes can be distinguished from basophils because it’s nucleus takes up nearly the whole cytoplasm-of the cell leaving a clear blue halo of cytoplasm around it.

Q

Hi why would low sodium level be a problem

A

Low sodium level may result in the lack of iron that is needed for nerve conduction and muscle contraction
