Pressure and solute concentration are the two physical factors that affect water potential. Pressure increases water potential, while solute concentration decreases water potential.
Oxygen, water and nutrients are delivered by the blood. Hormones also travel in it.
Distilled water would have a higher water potential than a red blood cell because the formula for obtaining water potential is -iCRT, where i=ionization constant, C=molar concentration, R=pressure constant--usually 0.0831 liter bars/mole K, and T=temperature in Kelvins. Since distilled has a molar concentration of 0, the water potential would be 0. And a red blood cell would have a negative water potential because it does have some sort of molar concentration. Thus, distilled water would have a higher water potential because 0 is greater than a negative number. As a note, water always flows from areas of higher water potential to areas of lower water potential. Therefore, it is easy to imagine that water flows toward more concentrated solutions, meaning it would flow to the red blood cell. If distilled water flows to the red blood cell, then it must have a higher water potential than the red blood cell.

Steroid hormones are "lipophilic" (they are fatty molecules which do not dissolve in water.) They would not normally dissolve very well in blood. Proteins are "hydrophilic" and do dissolve in water. Transport proteins bind to steroid hormones and allow dissolution in blood; they also serve to keep most of the hormone molecules inactive until needed.
When water potential in the blood decreases, the body may release antidiuretic hormone (ADH) to retain more water and decrease urine production. This helps to maintain blood volume and pressure. However, if water potential continues to decrease, it can lead to dehydration and an imbalance in electrolyte levels.
Pregnancy can affect the eyes and eyesight. The thickness and curvature of the cornea can be caused by water retention. The changes of blood circulation, metabolism, hormones, and fluid retention are all affects during pregnancy.
Some factors which influence water potential include gravity, pressure, and solute concentration. Adding solute lowers the water potential. An increase of pressure will increase the water potential.
Hormones that are not soluble in blood are typically steroid hormones and thyroid hormones. These hormones are lipophilic, meaning they are fat-soluble and require transport proteins to travel through the bloodstream. Examples include cortisol, estrogen, and thyroid hormones like thyroxine (T4). Because they are not water-soluble, they can easily pass through cell membranes to exert their effects on target cells.
