Question

role of the following organs in digestion of food and stomach liver pancreas small intestine large intestine Villi rectum

Answer 1

The small intestine is lined with finger-like projections, called villi, which provide a very large surface area facilitating the absorption of nutrients, including carbohydrates, proteins and fats, into the bloodstream. The small intestine also plays a key role in regulating blood glucose levels.

Answer 2

hi mate,

==>Large Intestine. ... The wall of the large intestine has the same types of tissue that are found in other parts of the digestive tract but there are some distinguishing characteristics. The mucosa has a large number of goblet cells but does not have any villi.

==> The longitudinal muscle layer, although present, is incomplete.

Intestinal villi (singular: villus) are small, finger-like projections that extend into the lumen of the small intestine.

==>... Villi increase the internal surface area of the intestinal walls making available a greater surface area for absorption.

==>The rectum is a chamber that begins at the end of the large intestine, immediately following the sigmoid colon, and ends at the anus (see also Overview of the Anus and Rectum).

==>Ordinarily, the rectum is empty because stool is stored higher in the descending colon.

==>Functions of the Villi

We've already stated that the small

intestine's main job is to absorb nutrients from the food you eat and that your villi help by increasing the surface area the intestine has for absorption.

i hope it helps you.
