Its different for every person, and what that person eats. If you eat a food with a lot of fiber, it won't be there to long. Meat and bread take longer. As for the person difference, it depends on your metabolism, if you are a heavier or larger person, it will take longer to get through, a more fit person takes less time. So Anywhere from a few hours to a day or two.

What happens to a cheese sandwich that was eaten for lunch from the time it enters the mouth until it leaves the body at the anus?

the cheese sandwich first undergoes mechanical (chewing) and chemical (break down of starch by salivary amylase) digestion, then is made into a bolus (ball of food) and swallowed. The bolus then travels down the oesophagus into the stomach, where more chemical digestion occurs. From here, it is transported into the small intestine, where soluable substances are absorbed into the bloodstream, then what is left travels into the large intestine, where all water is absorbed into the bloodstream. What is left then is excreted out of the body through the anus as faeces.


Does cheese fall from trees?

No, cheese does not fall from trees. Cheese is made from milk and goes through a process of fermentation and aging to develop its texture and flavor.


How is rennet obtained and what is its role in the cheese-making process?

Rennet is obtained from the stomach lining of young calves or through microbial sources. Its role in cheese-making is to coagulate milk proteins, separating them into curds and whey. This process is essential for forming the solid structure of cheese.


What happens in the digestion when you eat a cheese sandwich?

When you chew a cheese sandwich the teeth grind down the cheese and the bread, the saliva breaks down the carbohydrates, using an enzyme called amaylase, in the bread, reducing them to maltose, as well as lubricating the food making its transtion down the throat easier. When the food reaches the stomach(lumen) it is churned in the stomach acid, and the cheese is digested by an enzyme called pepsin. When the pepsin has broken down the cheese in to poly-peptides the remainder of the food is passed down to the duodenum (also classed as the lumen), i think its under the stomach. Then in the duodenum the pancreas egests some more amaylase to breakdown the remainder of the carbohydrates, protases to breakdown the polypeptides into tripeptides and dipeptides, peptidases for the tripeptides and dipeptides into amino acids, and lipase for the butter to break it down into monogylcerides and fatty acids. Then its passed to the intestines where the remaining sugars from the carbohydrates are broken down into glucose. then all the nutrients and stuff are absorbed and the waste comes outta ya.


How do rats in a maze navigate their way to find the cheese?

Rats in a maze navigate their way to find the cheese by using their sense of smell and memory to remember the path they took to reach the cheese. They rely on their ability to learn and remember the layout of the maze to find the cheese efficiently.
