When recorcing blood pressures systolic is the pressure exerted on the arterial walls of the blood vessels when blood is leaving the heart to be pumped around the heart. Diastolic is the pressure...
it is higher up on Mount Everest so it has less pressure than at sea level
hydrostatic pressure - drives fluid out osmotic/oncotic pressure - solute/protein concentration that draws fluid in
It is different in that the seas don't have air pressure. No air; no air pressure.
yes because different gases have different mass and they will exert more of less pressure according to their mass
