You could explain to them the simple principle of 'If you don't use it, you lose it.' The body likes to conserve resources. So, if some part is not used, the body sends it less nourishment and does not clean out the waste products. In effect, reducing the circulation of blood in that area. Any kind of movement, whether it is passive or active, will encourage the body to provide more circulation to the area and even build up the muscle tone. It is not a substitute for exercise, but it can be considered along the same lines as the benefits of exercise to the body.
he or she passively submits to fate
That is the correct spelling of "passively" (in an indirect way, or in a deferential manner).

water passively follows salt
The root word of "passively" is "passive." "Passive" comes from the Latin word "passivus," which means "capable of feeling or suffering."
Osmosis.
Water is not removed by active transport in the renal tubules. It is primarily reabsorbed passively through osmosis following the movement of solutes like sodium and glucose.
Small, non-polar molecules like oxygen, carbon dioxide, and water can passively diffuse through cell membranes and be absorbed into the blood. Lipid-soluble molecules and small uncharged molecules can also passively cross cell membranes to enter the bloodstream.
IDS
A high level of salt in a cell would cause water molecules to move passively into the cell.
Passively, via diffusion.
