Question

Relate the function of small intestine to its unique structure

Answer 1

hey mate...

here is your answer...

Microvilli are hairs that aid in absorption of nutrients. In the small intestine, these cells contain microvilli, which are tiny hair-like projections that increase nutrient absorption. These projections increase the surface area of the small intestine allowing more area for nutrients to be absorbed.

hope it helps...

Answer 2

The blood vessels in the intestine's walls absorb the food that has been digested.

Functions of the small intestine:

• The duodenum, jejunum, and ileum are the three sections of the small intestine.
• It aids in the further digestion of stomach-born meals.
• It takes in water, vitamins, minerals, carbs, lipids, and proteins from food so that the body can utilize them.
• The digestive system includes the small intestine.
• In humans, it is the location of full digestion.
• Complete digestion of the meal is absorbed.
• The digestive juice is secreted.
• It receives pancreatic juice from the pancreas and bile juice from the liver.

Structure of small intestine:

• The small intestine has a wall made up of serosa, smooth muscle with inner circular and outer longitudinal layers, submucosa, and mucosa with simple columnar epithelium. This structure is similar to that of the digestive tract as a whole.
• The small intestine's surface area is greatly increased by the finger-like extensions called villi, allowing for higher absorption of the food that has been digested.
• The blood transports the ingested dietary components to various bodily regions.
