What is the difference between the ileum and the duodenum?

The major difference is that, Duodenum is responsible for absorption of hard particles like iron particles in contrast to the function of jejunum in which absorption of fully digested carbohydrates and fully digested protein take place. However, in ileum absorption of remaining non-absorbed particles take place.

Is ileum a tissue or a cell?

The ileum is entirely covered by serosa from the outside. It is made up of simple squamous epithelium and a connective tissue layer underneath (lamina propria serosae). A characteristic feature of the ileum is the Peyer’s patches lying in the mucosa. It is an important part of the GALT (gut-associated lymphoid tissue). One patch is around 2 to 5 centimeters long and consists of about 300 aggregated lymphoid follicles and the parafollicular lymphoid tissue.
