"Within 75 seconds, the number of circulating red blood cells doubles."

The medical term for low levels of circulating red blood cells is anemia.

Plasma is needed to circulate red blood cells that deliver oxygen throughout the body.

Lymphocytes normally represent 20 to 40% of circulating white blood cells.

Neutrophils usually make up 50-70% of circulating white blood cells and serve as the primary defense against infections.

However, circulating infected blood cells are destroyed in the spleen.

People with this disorder also have a reduced number of circulating red blood cells (erythrocytes).

Not only were objective responses observed after 60 days, but a decrease in levels of circulating endothelial cells was also found.

The results suggest that IL-2 exerts a broad range of effects on circulating cells.

The cell is released from the bone marrow after Stage 7, and so of circulating red blood cells there are 1% reticulocytes.
