What is the purpose of the pyloric valve?
It serves to regulate the movement of food out of the stomach and prevents bile in the small intestine from moving back into the stomach.
What chemical and mechanical digestion take place in the stomach?
Stomach acid serves to slightly sterilize the contents of the stomach. The fluid contents of the stomach serve to hydrate the consumed foods. The stomach's motions serves to break the food down physically into slightly smaller size.
How does esophagus work?
it serves as a passage of food and water from the mouth to the stomach
Where is the lacteal located?
The lacteal is found in the small intestine. It serves the purpose of absorbing fats from the gut into the bloodstream.
What bone serves as a brace between the sternum and the scapula?
Clavicle.
What controls the passage of food from the stomach to the small intestine?
There are structural (anatomical) and functional (physiological) ways the digestive system regulates how food is passed from the stomach to the small intestine. The major anatomical regulators are the pyloric sphincter (a muscular band that acts like a valve to open and close the connection between the stomach and small intestine) and the pyloric antrum (the part of the stomach commonly associated with stomach motility, mixing, and propulsion of stored foodstuffs into the small intestine). When the pyloric sphincter is relaxed and the antrum is active, food is propelled into the small intestine; when the sphincter is constricted and the antrum is relaxed, food is stored in the stomach. A number of physiological factors exist that regulate the activity of the pyloric sphincter and antrum. The principal regulators are nerves and hormones involved in the digestive process. The vagus nerve is an example of a nerve with major regulatory effects on motility of the stomach and small intestine. Gastrin and cholecystokinin (CCK) are gut hormones also involved in stomach motility. Gastrin is secreted in response to food (particularly amino acids, the building blocks of proteins) in the stomach and stimulates antral motility that serves to mix food. Strong antral contractions cause opening of the pyloric sphincter and the movement of food into the small intestine. CCK is released in response to foodstuffs (particularly fats) in the small intestine and inhibits antral motility of the stomach.

Where is the cecum is located?
The cecum is located in the first part of the large intestine. This serves as a connection between the ileum to the ascending colon and a part of the intestine that moves the waste to be excreted.
Can you breath though your butt?
No. The anus only serves as an exit for waste. There are often large obstructions in the large intestine, in addition to impassable sphincters separating the large and small intestine and the small intestine and the stomach, and the presence of lots of liquids in the small intestine and the stomach. You can breath through your mouth, your nose, or (in the case of some smokers) a small recessed hole in the neck directly connected to the windpipe.
How does the function of the stomach differ from that of the small intestine?
The stomach serves first as a receptacle for swallowed food. Second, it begins the chemical digestion of the food by bathing the food in acid, turning it into kind of mush. The small intestine is where the nutrients are absorbed from the food. Anything that is not absorbed into the bloodstream is considered waste and fiber. This is passed on to the large intestine where is is eventually eliminated.
Why do birds eat their own feathers?
Grebes swallow their own feathers, which accumulate in the region between the gizzard and the intestine following it. This feather-clogged zone then serves as a filter for sharp fish bones that somehow make it past the stomach.
How does the large intestine differ from the smaller one?
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.
What does a perch's pyloric caeca do?
The Pyloric Caeca is a finger-like out-pocketing of the intestine where it meets the end of the stomach (pylorus). Also spelled cecum (ceca). Serves to aid digestion. It is basically where digestion occurs, as it aids the stomach in digestion.
How and why does bile neutralise stomach acid entering the small intestine?
Bile salts and acids are transported in a fluid that contains water, sodium, chloride, and bicarbonates. This fluid is produced in the liver, and it serves to neutralize hydrochloric acid passed from the stomach into the small intestine.
What serves as an emulsifying agent in the small intestine?
bile
What is the purpose of bicarbonate in the small intestine?
Bicarbonate's main role is to help neutralize the very acidic contents coming out of the stomach and into the small intestine. This serves a protective role -- to help protect the lining of the small intestine from being eaten away -- as well as a functional one -- the digestive enzymes at work in the small intestine operate better at a higher pH (less acidic).
