Osmosis And Diffusion Lab Report

In order for the human body to be in equilibrium we need diffusion and osmosis to regulate the movement of substances. This not only occurs in plants and animals but in humans too. Diffusion is a form of passive transport since it does not require energy, and since osmosis is a specific type of this dispersion it does not require cellular energy as well. Yet it still needs kinetic energy. As small as these two mechanisms are they occur in our body on a daily basis.
Diffusion is an extended way of transportation, in which a substance flows from high concentration to a low concentration area. In other words, it means when something is too full or concentrated it needs to get rid of that excess substance, so it moves to a lower consolidation. …show more content…
Instead it is the movement of water from a low to high concentration. In this situation the process varies due to an alteration in conditions. These might include membrane size, pressure, etc. Water being the solvent moves in between a semi-permeable membrane in one direction always from the less concentrated area to a high. The semi-permeable passage is the major reason osmosis only deals with water, as its properties only allow certain components to flow through. The membrane contains small holes in which small molecules such as water can pass through. During this movement weather the water is moving in or out of the membrane the tonicity chances. It can either be hypertonic where the concentration is higher outside the cell and water moves out, or hypotonic where its lower outside the cell and water moves in. It will always be one of the two depending on the movement of …show more content…
Osmosis needs to keep water balance in tact as a person adds diuretic substances into the body. A diuretic is an inhibited element which causes the kidneys to allow a surplus of water loss. Creating an imbalance. Diuretics are very common, and people drink them often which keeps osmosis working at a constant rate. A particular type of this substance is caffeine, generally found in coffee and soda. Since these two refreshments are usually consumed by people causing too much water in the lungs osmosis comes in and regulates the amount of water in the lungs. It does this by sending a message to the kidneys telling them to absorb more water, moving from low to high concentrations. This prevents dehydration in the
