Most endocrine hormones are circulating hormones, they pass from the secretory cells that make them into interstitial fluid and then into the blood. circulating hormones are carried through the bloodstream to act on distant target cells. Paracrines act as neighboring cells, and autocrines act on the same cells that produced them.
No, it cannot divide since mature red blood cells have no nucleus. there are no chromosomes to replicate.
red blood cells gradually become filled with hemoglobin, their nuclei and other organelles are forced out. Thus, mature red blood cells do not have nuclei.

Mostly hemoglobin, which give blood its red color. The red blood cells also help carry oxygen throughout the body.
An abnormal increase in the number of circulating red blood cells.
Yes, mature erythrocytes are still cells and are still living. In most mammals the circulating red blood cells do not have nuclei, so they are unable to repair themselves when damaged and eventually die due to the accumulated damage.
No. Mature red blood cells have neither a nucleus nor chromosomes.
The circulating blood
An embolus is a foreign object, such as a blood clot or bit of tissue or tumor, that is circulating in the blood.
red blood cells
It is actually the other way around - mature red blood cells lack a nucleus.
In blood
Red cells, at one time contained nuclei; however, when circulating in your blood stream, they do not.
