Answer:
In Gastrointestinal system:
When we eat food or drink water, it travels from our mouth, down our oesophagus and into our stomach. In the stomach, the food is broken into tiny pieces that are mixed with stomach liquids. This mush of food and stomach liquids is called chyme. The chyme travels into the small intestine. This is where osmosis takes place.
In our Kidneys:
Our kidneys keep blood and tissue fluid (internal environment) 'clean' by removing urea, excess water and other wastes and excreting them. This controls the amounts of dissolved substances in blood and tissue fluid, a process called osmoregulation. If tissue fluid becomes too concentrated, cells will lose water by osmosis and become dehydrated and if it becomes too dilute, cells will take in excess water by osmosis.
