What are the longitudinal muscle bands in the large intestine?
they are a band of longitudinal layers has been reduced to the muscular bands of the taeniae coli. It helps for mixing and propulsive contractions
Where do haustral contractions occur in the GI system?
In the Colon of Large Intestine
What muscle is located between the small intestine and the large intestine?
Ileocecal valve
Is the large intestine a muscle?
Yup definately :)
WhichOrgan located between the stomach and the large intestine?
The sphincter muscle, or ileocecal valve is located at the junction of the small and large intestine.
What is perstalsis?
Food is pushed down the oesophagus by a series of contractions. The part of the oesophagus just above the ball of food contracts and pushes it down. then it relaxes and the next part of the oesophagus contracts. this wavelike movement, controlled by muscles, is called peristalsis. It occurs all the way down the alimentary canal.
What is a haustration?
Haustration is the mixing of feces to expose it to the surface of intestine to absorb water. they are sac like structures foldings in large intestine. At each of these constrictions, about 2.5 centimeters of the circular muscle contracts, sometimes constricting the lumen of the colon almost to occlusion. At the same time, the longitudinal muscle of the colon, which is aggregated into three longitudinal strips called the teniae coli, contracts. These combined contractions of the circular and longitudinal strips of muscle cause the unstimulated portion of the large intestine to bulge outward into baglike sacs called haustrations.
Why Have contracion for 10 hours but the las hours are more at your lowerarea you feel like haven a period an feelin to go defecation?
As baby falls lower its weight presses more on large intestine which holds your stool (bowel movements). The period like feelings are the contractions of the muscle of the uterus which holds the baby, and the muscle is trying to push the baby out. These contractions hurt.
Which is the only digestive structure with three muscle layers?
Large Intestine
What structure is found at the junction of the small and large intestine?
The sphincter muscle, or ileocecal valve is located at the junction of the small and large intestine
Where does the involuntary contraction of the muscles that push food forward?
Where does it occur? Throughout your entire GI (digestive) tract! Lets start from the top: Esophagus: Your esophagus is a long tube that goes from your throat to your stomach. It has two types of involuntary muscle contractions. One is vertical, so it pushes the food down, and the other is a circular wave that knocks all the food off of the walls of the esophagus to ensure that all the food makes it to the stomach. Stomach: Your stomach's three involuntary muscle contractions are the most interesting. Two of its contractions are the same as the esophagus, vertical and horizontal. It has a third, interesting type though. Once the food gets pushed to the bottom of the stomach, a contraction occurs that literally throws the food back into the digestive juices to continue breaking it down. This process occurs until the food is fully broken down. Then it makes its way to the small and large intestine. Small/Large intestine: The muscle contractions of your small and large intestine are very slow to allow absorption of all the nutrients in your food. Once food reaches the large intestine, a muscle contraction that lasts about a minute each time occurs about every 20 minutes to move the food further and further down. This is why it takes a day or two for food to make its way out of the body. Hope this answered your question! -Jennifer D.
What structures controls the passage of materials from the small intestine to the large intestine?
The iliocecal sphincterThe ileum is the last (and longest) portion of small intestine. It empties into into the cecum (the first part of the "large intestine") at the iliocecal junction. The iliocecal sphincter is a ring of invountary smooth muscle at this junction, controlling the passage of digestive contents from the small intestine to the large intestine.
