Błagam musze przetłumaczyć ten tekst a jestem bardzo słaba z angielskiego, niech mi ktoś pomoże!!!!!!!Objectives: To understand that digested food in the gut is still outside the body. To know how the small intenstine is adapted to the function of absorption of digested food. To understand the part played by the live in the assimilation and distribution of absorbed foods. Absorption of the products of digestionEnzymes in the gut convert large, insoluble molecules to small, soluble molecules. These soluble molecules are transported across the lining of the gut into the bloodstream a process called absorption. They can then be distributed to the parts of the body where they will be used. Most absorption happens from the ileum the lower part of the small intenstine. The ileum is very well adapted to perform this task:-it is very long, about 6m in an adult human so food takes a long time to pass through it and there is enough time for absorption to occur,-the surface of the ileum is highly folded which gives a much larger surface area for absorption than a simple tube would.The lining of the ileum is folded into hundreds of thousands of tiny finger like structures the villi which project out into the liquid digested food. The structure of a villlus and its adaptations to increase absorption are shown in the diagram below.Fellowing absorption in the small intenstine the contents of the gut are little more than water and indigestible matter. Most of the water is reabsorbed into the bloodstream from the colon part of the large intenstine. Some minerals and vitamins are also absorbed here.
