A typical cell mass is 1 nanogram, but all cells are different sizes and masses. For example, the largest known cell is that of an unfertilized ostrich egg cell. The smallest knwon independent cell is that of Nanoarchaeum equitans.
Blood accounts for about 8% of the human body weight. The average adult has a blood volume of about 5 liters (1.3 gallons).
Brain cells of the cerebral cortex (the grey matter) are with you from birth.

The surface area to volume ratio is how big the cell's membrane's area is compared to the volume of everything inside the cell. If the volume becomes too large, the cell will not be able to release waste or receive necessary nutrients as easily. Plus, the cell's DNA can't keep up with the cell.
The answer depends on what aspect of the human white blood cell you are referring to: their number in an average person, their mass, radius, volume, etc.

There are a number of contenders for the position of smallest cell in the human body. The head of the sperm is on average 5 to 6 micro meters. The flagellum is up to 50 micrometers long. Also some says Granule Cell of the Cerebellum is the smallest cell of the human body it is approximately 4um to 4.5um in size. The size of the RBC also found as around 5 micrometers. In terms of volume most of the scientists suggest that sperm is the smallest cell.
The size of a typical bacterial cell is 0.5-5.0 micrometers, a average human cell is 10 micrometers.
A childs mouth can hold 37.5ml of liquid.
An average human muscle contains around 750-1000 mitochondria per cell.
An average adult has a blood volume of 170 fluid ounces.Females tend to have less blood volume than males.
