Factors Affecting the Natural Frequency. The actual frequency at which an object will vibrate at is determined by a variety of factors. Each of these factors will either affect the wavelength or the speed of the object. an alteration in either speed or wavelength will result in an alteration of the natural frequency.
Eight vital organs can be donated: heart, kidneys (2), pancreas, lungs (2), liver, and intestines. Hands and faces have also recently been added to the list. Tissue: cornea, skin, heart valves, bone, blood vessels, and connective tissue.
In these very limited cases (approximately 20,000 per year), organ donation occurs when mechanical support (i.e., ventilators) can continue the viability of the organs for a short period of time after the death of the patient. Organs (heart, liver, kidney, etc.) must be carefully matched to waiting recipients.
