Cavitation (biology)
In biology and medicine, cavitation generally means the formation of cavities in tissues and organs. In the disciplines of biology, the term is used for different processes.
botany
In botany, cavitation or embolism usually means the formation of gas bubbles in the xylem of plants, which impairs the transport of water. Cavitations are not uncommon in plants, as investigations with sensitive sound detectors have shown. The water flow is i. d. Usually diverted via neighboring vascular elements. Cavitations can be eliminated by changing the water potential and the associated excess pressure.
Medicine and zoology
In medicine, cavitation is the formation of atypical, often disease-related, cavities in an organ. Medical cavitation occurs primarily in the lungs as a result of tuberculosis .
In medicine, low-frequency, bundled can ultrasonic waves a physical cavitation trigger within the body as to cause harmful thermal or mechanical effects in the tissue to tissue destruction. In cosmetic surgery , this effect is used to reduce fat cells .
