The term applied when water passes through a selectively permeable membrane from an area of high to low concentration is called osmosis. Osmotic pressure is defined as the amount of external pressure that is required to stop the net movement of the solution across the semi permeable membrane. In terms of biology, osmosis has great importance as most of the membranes in our body are semi permeable. Permeability depends on several factors such as charge, solubility, solute size and chemistry. Osmosis is the process that provides the primary means through which water travels in and out of the cells.
The organ which plays the primary role in prompting individuals to seek food is the brain. The brain is one of the most important organ of the nervous system. It is comparable to the CPU of a computer. It is repsonsible of processing information that it is receiving from all the senses and send the message back to the organs for a response.
