Osmotic pressure is related to the amount of fluid in the human body. In the context of osmotic pressure, it is worth mentioning osmosis, which is also an important criterion for the water balance. Osmosis is the transport of solvent particles through a semi-permeable membrane that separates the solution and the solvent. Due to the osmotic processes, the amount of ions inside the organisms is appropriate. The osmotic pressure is related to the temperature, concentration and type of substance.
Osmotic pressure and blood
Our blood is determined by properties such as: color, viscosity, taste, smell, pH and osmotic pressure. The value of the last of these characteristics should be around 6,5 atmospheres (300 mOsmol / l). If the level osmotic pressure changes, this could mean, among other things, that the food we had eaten had too much salt. Hesitation pressure it is also associated with excessive fluid consumption, but also with the loss of more water through our skin, kidneys, digestive tract and respiratory system. In height osmotic pressure in the blood is affected by the level of electrolytes. Interestingly, the level pressure affects erythrocytes. If osmotic pressure adequate and durable, red blood cells can retain their shape and membrane structure. In a situation where pressure is decreased, haemolysis may occur. It is the breakdown of red blood cells by breaking their cell membranes.
Osmotic pressure of body fluids
In the case of osmotic pressure body fluids, its value should also be the same. It is worth noting that the function of body fluids is based on maintaining the immunity of cells. Body fluids include lymph which travels in the lymphatic system, consisting of the bone marrow, thymus, spleen, lymph nodes, tonsils and Peyer’s tuft. These segments ensure that microbes do not enter the body. It should not be forgotten that blood is also a body fluid that is part of our circulatory system. Its tasks include guaranteeing resilience, supporting it osmotic pressure, pH and temperature. The circulatory system is also the phenomenon of blood clotting or the transport of carbon dioxide, as well as cleansing the body of harmful metabolic products.
Irregularities in the water and electrolyte balance may appear during physical exertion. Excessive sweating during activity results in the loss of body fluids and water. Then, there may appear: faulty regulation of the body’s temperature and metabolic processes, increased temperature, muscle cramps, and reduced physical endurance. It may even be fatal. Therefore, you should replenish your fluids. If we want to provide them to the body after physical exertion, we can reach for isotonic drinks. It is also important that the work of our kidneys has a huge impact on the stabilization of the amount of fluids. When there are even slight changes in value osmotic pressure and the concentration of electrolytes, our kidneys take up work to stop or eliminate a specific amount of water.
How to calculate osmotic pressure?
Taking up the subject of calculation osmotic pressure, it makes sense to start with the pattern that comes with it. Osmotic pressure is represented by Π = iMRT. The first symbol means osmotic pressure. The next one is the Van’t Hoff factor of the oil. M is the symbol for molar concentration, R represents the universal gas constant and the letter T represents the absolute temperature.
Height osmotic pressurecaused by the movement of water through the cell membrane is related to the solute concentration and temperature. Osmosis also affects how a solute behaves in water. It is worth recalling the Van’t Hoff principle, which shows how intensely the temperature affects the rate of reaction. As we know, this is an element needed for the calculation osmotic pressure.
Osmotic pressure and oncotic pressure
It’s good to know that oncotic pressure is a kind osmotic pressure. In oncotic pressure is affected by a colloidal solution of proteins that are found in the blood plasma. Oncotic pressure is higher than osmotic pressure within tissue fluids. This is due to the fact that the concentration of proteins in the blood plasma is higher than that found in the intercellular fluid. Thanks to this, it is impossible to seep water with electrolytes from the blood plasma into the tissues. For regulations oncotic pressure albumin is mainly responsible. These are proteins that are produced in our liver. During disease states such as malnutrition or proteinuria, which is accompanied by a decrease in the level of proteins in the plasma, decreased oncotic pressuree may provoke the appearance of edema. This signal is one of the first symptoms of liver failure. It’s also worth knowing that oncotic pressure is indicated by the symbol π.
