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.
absorption - nutrients are passed or absorbed from the small intestine to the hepatic portal circulation to be processed by the liver.
it's absorption :))
absorption
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.
It increases the surface area of the inside of the intestine, this allows for more area where nutrients can be absorbed.
Circulatory system
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
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
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.
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.
Pepsin breaks apart proteins to form smaller particles called peptides. Peptides are more easily digestible by the smaller intestine
