||Abstract:"...reports on the frequencies and the absolute numbers of B and T lymphocyte subsets within various human tissues and fluids have been collected from a wide variety of journals and are briefly summarized here."
||Caption to fig. 2:"Comparison of the size of different lymphoid organs in a young adult drawn from data in [ref 58]. The number of lymphocytes within the different organs are indicated. The size of the rectangles corresponds to the number of lymphocytes contained by the respective organ. The circle represents the number of lymphocytes migrating through the blood each day [ref 40]. Although the blood contains only a very small number of lymphocytes, each day about 500×10^9 lymphocytes travel through it, which is approximately the same as the number of lymphocytes contained within the whole human body (the area of all rectangles equals that of the circle)" p.541 right column top paragraph:"The blood contains very few lymphocytes, only about 2% of the total lymphocyte pool." p.542 left column 2nd paragraph:"Although the blood contains only 2% of all
lymphocytes, in the human body it is the most
frequently used compartment for defining lymphocyte
subsets, probably because it is easily accessible."
