a) It never needs batteries.
b) It's designed for extremely active patients.
c) It's specifically designed for long-term use.
d) An LVAD only supports a failing left ventricle.
Answer:
d) An LVAD only supports a failing left ventricle.
Explanation:
When both halves (R.&L Ventricles) of the heart failed to pump blood, together with the failure of the valves to regulate blood flow as in biventricular failure, <em>a device can planted in the patient to replace the failed right or let ventricles and to control the directional flow of blood to the vascular system. This device is called TAH.</em>
However when the left ventricle is faulty so that blood pump into the systemic circulation is affected in case of a patient who is <u>waiting for heart transplants not old enough for transplants;</u> <u>who needs to sustain heart function after surgery</u>; or <u>patients who could not find a heart donor and therefore need to survive</u>, <em>a mechanical pump is implanted below the diaphragm and power by battery cell in a wearable outside. This miniature mechanical pump is called Left venticular assist device(LVAD).It only correct left ventricle anomaly</em> .
Thus the major difference between the two is that LVAD, is only for the faulty left Ventricle correction.
The tropical rainforest is one of the world’s most threatened biomes, despite being home to some of the most diverse and unique species on the planet. Many of the world’s most colorful creatures reside in rainforests, and animals from tiny organisms to large wild cats find homes amongst the range of plant life.
For many years tropical rain forests were safe from the presence of man, other than native tribal individuals who lived harmoniously with the land, but the problem of man’s encroachment on rain forests for lumber, agriculture, and development is having serious effects on the long-term survival of these regions.
This is Adaptation !
An adaptation is when an animal adapts or evolves to it's environment.
^ There are more uses for the word Adaptation but in this example this is correct. Hope this helps !!!
