Short-term regulation of feeding involves signals coming from the liver and GI tract. Stretch receptors send afferent signals through the vagal nerve fibers to the chemoreceptors in the stomach and proximal small intestine,
Short-term regulation food intake is primarily regulated by food signals resulting from both their preabsorptive action in the gut and their postabsorptive metabolism, as opposed to long-term food intake, which is regulated by adiposity signals. The first process, commonly referred to as short-term regulation, tries to consume enough energy to counteract what is being used up. It is typically believed that this short-term mechanism controls both the interval between meals and the amount of the meals.

The immune cells such as antibodies possess cell surface receptors which detect the foreign objects or antigens. When the cell surface receptors detect any antigen they immediately recognize that a foreign particle has invaded the body and they then identify it and start to generate response.
