Because the longer the length of the small intestine, the more surface area and more time there is for nutrients to be absorbed
A cat's intestine is typically around 3-4 times the length of its body, ranging from about 20-40 inches in length. This length is necessary for digesting and absorbing nutrients from their primarily carnivorous diet.
The large intestine differs from the small intestine in length, diameter, and function. The small intestine is longer than the large intestine, but has a smaller diameter. The small intestine is directly connected to the stomach. The primary function of the small intestine is to absorb nutrients from the food processed by the stomach and to transfer those nutrients to the blood stream. The large intestine comes after the small. Its primary function is to capture water from the waste materials that pass to it from the small intestine. It also serves as a place to store the waste solids until they can be eliminated from the body.
The small intestine is about 5 meters long; this provides a large surface area for the absorption of nutrients
In earthworm, typhlosole is a dorsal flap of the intestine that runs along most of its length. Its function is to increase intestine surface area for more efficient absorption of digested nutrients. In different earthworm families, the typhlosole appears to have multiple origins
the reason the small intestine is so long is because it abosorbs nutrient to keep u healty !!!!the small intestine is roughly 250 m long (the size of a tenis court)The nutrient the small intestine absorbes are; water,electrolytes,carbs(after digestion to monosaccharides) protein (if the stomach didnt get it all),lipids(fats),vitamins and minerals.
the lengthb increase the surface area so that it can better absorb nutrients
The human alimentary canal, or digestive tract, is approximately 30 feet in length and consists of the mouth, esophagus, stomach, small intestine, and large intestine. Its main function is to digest food, absorb nutrients, and eliminate waste from the body.
The colon is another name for the large intestine. The colon creates waste by absorbing water. The average colon is five feet long.
The intestine.
The Ileum is responsible for absorption of nutrients into the blood stream. Also the jejunum has the same functionThe Ileum is the last section of the small intestine (its about 12 feet/ 3.6m in length) and joins the large intestine at the ileocecal valve. The role of the small intestine as a whole is its the major digestive system of the body. Digestion is completed in the small intestine and virtually all absorption of nutrients occurs here.the ileum absorbs B12 and bile salts and whatever products of digestion that were not absorbed by the jejumType your a What is the function of the ileum?nswer here... the thing that yeah!
Because it takes time to absorb food.
The small intestine averages between 22 and 23 feet in length for the average person. Its length helps it perform its two main functions of digestion and absorption: because of the organ's length, food spends enough time in the small intestine to be fully broken down and for the nutrients to be absorbed.
