why are muscles needed in the intestines?

Question

for my science homework [im in year 9] thankkss :D

Answer 1

To push food through your intestines.

Search Yahoo for peristaltic motion. It should help you understand why.

Answer 2

The entire small intestine is lined with intricate sets of muscles which are never at complete rest. One group produces a swaying motion that churns together food and digestive juices. Another set of muscles produces a wavelike action; the waves push the contents along a few inches, then die out. These muscular contractions cause a ripple-like movement that carries the contents down the small intestine - somewhat like a conveyor belt.

Answer 3

You need muscles in the intestines to continue the peristalsis through the digestive tract. Just like the muscles in your esophagus move a food bolus to the stomach, the muscles in your intestines move the bolus out of the body. Without muscles, the food would sit there until it either was pushed out by other food or burst the intestine. Yikes!

Answer 4

The muscles in your digestive system, smooth muscles to be specific, create peristaltic waves that push food throughout your intestines in one direction to get the nutrients to where they need to be and to facilitate waste removal.

Answer 5

Again, to move your intestines to get the food passing thru to your lower colon and out your anus. If your muscles have problems you can develop problems such as Graves Disease.

Answer 6

How else would you poop or move food throughout your digestive tract to be absorbed and broken down better??
