To v\u0161e lze snadno pochopit.\t\u010casto se ov\u0161em zapom\u00edn\u00e1, \u017ee proti gravitaci bojuj\u00ed i rostliny, kter\u00e9 ke sv\u00e9mu \u017eivotu pot\u0159ebuj\u00ed dostat m\u00edzu do v\u0161ech sv\u00fdch \u010d\u00e1st\u00ed. Zaj\u00edmav\u00e9 je to nap\u0159\u00edklad u strom\u016f, kter\u00e9 jsou vysok\u00e9 i des\u00edtky metr\u016f. Lze si tedy p\u0159edstavit, co je pot\u0159eba k\u00a0tomu, aby se m\u00edza dok\u00e1zala dostat a\u017e nahoru do koruny. Je v\u0161ak pravdou, \u017ee syst\u00e9m, kter\u00fd to umo\u017e\u0148uje, zde rozhodn\u011b je.\tV\u00a0prvn\u00ed \u0159ad\u011b si mus\u00edme uv\u011bdomit, \u017ee gravita\u010dn\u00ed s\u00edla nen\u00ed nijak velk\u00e1. Pr\u00e1ce, kterou k\u00a0jej\u00edmu p\u0159ekon\u00e1n\u00ed mus\u00edme vykonat, tedy tak\u00e9 nen\u00ed nejv\u011bt\u0161\u00ed.

P\u0159esto n\u011bjakou vy\u017eaduje. Kde je tedy vezmeme?\tOdpov\u011bd\u00ed je vztlakov\u00e1 s\u00edla. V\u00a0m\u00edzn\u00edch kan\u00e1lc\u00edch je ur\u010dit\u00fd podtlak, d\u00edky kter\u00e9mu je tato tekutina v\u00a0podstat\u011b neust\u00e1le nas\u00e1v\u00e1na. Tak se pom\u011brn\u011b snadno dostane v\u0161ude, kde je pot\u0159eba. P\u0159i cest\u011b zp\u011bt pak nen\u00ed vyu\u017e\u00edv\u00e1n\u00ed speci\u00e1ln\u00edch technik nutn\u00e9. Zde se m\u016f\u017eeme pln\u011b spolehnout na starou dobrou gravitaci.\t\tA\u010dkoliv by se to nemuselo zd\u00e1t, uk\u00e1zalo se, \u017ee tento syst\u00e9m je mimo\u0159\u00e1dn\u011b efektivn\u00ed.
