The osmotic pressure of the plasma affects the mechanics of the circulation in several ways. An alteration of the osmotic pressure difference across the membrane of a blood cell causes a shift of water and a change of cell volume. The changes in shape and flexibility affect the mechanical properties of whole blood.
Weekly. Potatoes need one solid watering every week. Accounting for naturally occurring moisture is an important when judging how often to water. A light shower doesn't penetrate deeply enough into the soil, so you should still proceed with your weekly watering after receiving one.
