Typically it is dried blood from a small capillary. They are found at the center of the wart.
The real answer is wart
It is the root and hopefully it will fall off soon
Most can be distinguished by appearance. However, there are always exceptions. Warts have a very typical appearance (google image search) with a rough surface and often little black dots inside (thrombosed or clotted capillaries). If it falls off, it was probably a wart, but since warts can last years, that's not a good rule of thumb. If in doubt, show your doctor. The safest answer if he/she isn't sure is to do a biopsy!
As a pathologist, I've seen the term used for lesions that appear wart-like, but do not have all of the features needed for a definitive diagnosis of a wart. The histological differential diagnosis includes verruca vulgaris (wart), seborrheic keratosis, prurigo nodularis, and lichen simplex chronicus. The important thing to keep in mind is that these lesions are all benign.

A family physician or podiatrist may scrape skin off what seems to be a callus, but may actually be a wart. If the lesion is a wart, it will bleed. A callus will not bleed, but will reveal another layer of dead skin.
apply some wart or boil cream and you should be sweet, but depending on how bad it is I suggest its give or take
Total number of casualties, both wounded and dead, is 37 million.
