The basic unit into which the lithosphere is broken is a plate.
According to the plate tectonics the Earth's lithosphere is broken into many pieces that move slowly over the asthenosphere (the soft, flexible layer of the mantle on which the tectonic plates move and float). These tectonic plates move at a rate of centimeters per year. Lithosphere is the chunk of crust and upper mantle that moves the Earth's surface. Therefore; one would say the tectonic plates, are the blocks, chunk or pieces of lithosphere that move around on the top of the asthenosphere.
It relates perfectly because the experts of respiratory therapy are usually dealing with patients that can’t breathe or are having <span>blockage in their lungs. The exmaple could be in an emergency room where a person cannot breathe and the therapists checks the volume of oxygen in the patient and his lungs to see if there is something blocking the airways</span>
I believe it is, || and |||
The intervertebral discs, which are between vertebrae, are the parts that prevent the vertebrae from grinding against one another.
The intervertebrals discs act as a cushion; they absorb the stress and shockw that occur during movement, preventing such grinding.
Well, the asthenosphere is located in the upper mantle. So that is how they are related.
