Absorption is the process that allows food to move from the small intestine to the blood stream. Absorption is critical because it allows the nutrients to be used by cells throughout the body.
An organ called the blood, circulated by the circulatory system.
The hole that allows food from the stomach into the small intestine is called the pylorus. It is a muscular valve located at the lower end of the stomach. When it relaxes, it allows the partially digested food (chyme) to pass from the stomach into the small intestine.
The small projections lining the walls of the small intestine are called villi. They increase the surface area of the intestine, which allows for more efficient absorption of nutrients from food into the bloodstream. This helps improve the nutrient absorption process in the digestive system.
The normal name for that is, "Intestinal Juice".There is a scientific name,but it has not been posted on this question.
The constriction at the end of the stomach and beginning of the small intestine is the called the pylorus. Its significance is that it regulates the passage of large and undigested particles into the ileum. It also prevents the contents of the small intestine from entering the stomach.
The small intestine
The small intestine doesn't usually get sucked into the large intestine, but parts of the small intestine can telescope into itself. This is called intussusception.
The large intestine is called the colon, while enteron is a term for the intestine, both small and large.
food ingested is broken down into smaller pieces via mechanical and chemical digestion. this takes place in the mouth stomach and the intestine. it is then absorbed (taken in) by cells of the gut called enterocytes. these cells then transfer the nutrients into the capillaries supplying the gut. in this way nutrients from your diet enter the circulatory system to transfer them to other tissues
In a frog the first part of the small intestine is called duodenum. The second part is called the ileum. The small intestine leads to the large intestine.
the small intestine is called so because of its thickness not length . therefore the large intestine is called so because it is fat.
The finger-like projections found on the walls of the small intestine are called villi. They increase the surface area of the small intestine, which allows for better absorption of nutrients from digested food into the bloodstream.
