Osmosis in living organisms
Osmosis is the mechanism for transferring fluids and nutrients across membranes. It occurs in plants and animals and maintains the proper balance between extracellular and intracellular fluids. Although osmotic pressure is measured in the laboratory and has been referred to as a driving force for osmosis Osmotic pressure only occurs in laboratory experiments and calculations. …. Read More
Pressure
Vapor Pressure II As we noted previously, the osmosis process of molecular movement through a membrane is directly related to vapor pressure difference. This agrees with other models for fluid flow. Flow is directly related to pressure difference and flow proceeds from a high-pressure area to a low-pressure area. But, what is pressure? We introduce …. Read More
