An embolus is a particle that moves about in our blood vessels, either in the veins or arteries. Most emboli are composed of clotted blood cells. A blood clot is called a thrombus and a moving blood clot is called a thromboembolus. As an embolus moves through the body's blood vessels, it's likely to come to a passage it can't fit through. It lodges there, backing up blood behind it. The cells that normally get their blood supply via this passage are starved of oxygen (ischemia) and die. This condition is called an embolism.
Answers.comÂ® is making the world better one answer at a time. Growth that is due to an increase in cell number results from an increased rate of mitotic cell division and is termed hyperplasia. Consequently, growth of a tissue or organ due to an increase in cell size is termed hypertrophy.
The cell growth can be detected by a variety of methods. The cell size growth can be visualized by microscopy, using suitable stains. But the increase of cells number is usually more significant. cell is unable to get too small because the later cell cycle events, such as S, G2, and M, are delayed until mass increases sufficiently to begin S phase. Many of the signal molecules that convey information to cells during the control of cellular differentiation or growth are called growth factors.
