Digestive System

The teeth (in the mouth) - for chewing, and the muscles around the gut - for peristalsis.

Saliva is a liquid which comes into your mouth from the salivary glands in each cheek. Its main purpose is not to taste something, but it does alter the taste of foods, particularly starches which are turned into sugars. When we chew our food the saliva is mixed in with it, and this makes the food mixture soft enough to be swallowed. Saliva acts as a lubricant.

the steps of digestion:

1. the food enter through your mouth as the mechanical muscles(teeth and tongue) break down the food into smaller bits while the chemical(saliva or spit) breaks it down so it is easier to chew and swallow

2.next the food gets sent down to the esophagus where it uses muscles contractions to break down your food

3.it gets sent to your stomach where it takes about 10 for water to pass and about 3-4 hours for fatty foods to pass

4. next it gets sent down to the small intestine where the nutrients is taken out and pushed to the liver where it is kept and released

5.goes down to large intestine where your bowel movement is made and you will then release your feces once it hits ur rectum and exits from the body

Diarrhea is a disorder characterized by frequent, watery stools caused by irritation of the intestinal lining. This creates hyperactivity of muscle contractions (peristalsis), causing a rushing of the watery contents in the small intestine through the large intestine. This rushing does not allow the large intestine the time needed to reabsorb the water which equates to diarrhea.

the respiratory system and the digestive system share the Pharynx. The Respiratory system contains the eppiglottis, which keeps food going down the esophogus instead of the trachea

The muscular movement of the intestinal canal is called peristalsis.

Digestion of some fats can begin in the mouth where lingual lipase breaks down some short chain lipids into diglycerides. However fats are mainly digested in the small intestine. The presence of fat in the small intestine produces hormones that stimulate the release of pancreatic lipase from the pancreas and bile from the liver which helps in the emulsification of fats for absorption fatty acids.

The digestive system does not have as one of its functions the need for nutrients, apart form them needed to keep it healthy and functioning. It is more appropriate to ask, what nutrients do the cells of the body need? And how can the digestive system function optimally in order to accomplish that goal?

The purpose of the digestive system is to break down foods in order to supply nourishment to the cells of the body. So, ultimately, it is what we choose to ingest that will provide the nutrients that our body needs. The digestive system is just an avenue for good nutrition to be supplied to the body.

So, to answer your question more technically: All nutrients are involved in the digestive system because that is how the nutrients gain access to all the cells in the body.

Those things that you eat that are made of cellulose help clean your colons because cellulose is one of those things that the human body can't completely break down.

It distributes bile and pancreatic acids to help break down food

Because of all the fat and carbs an average of 4 to 6 hours depending on your age and exercise

More than 50% must be removed before there is a significant reduction in capability

Duodenum and jejunum can perform each other's roles in digestion and absorption

Digesting food is a very good example of a chemical change. However, it is also a common example of a physical change with the body.

Plain cooked chicken is probably one of the best foods to give your cat in the case of an upset stomach. Chicken is very bland and easy to digest.

Additionally, you could give your cat a malt paste called Pro-Kolin. It helps promote a healthy digestive system and thus helps settle an upset stomach. Most cats like the taste of this, too.

the three organs in your digestive system are the intestines, stomach, and liver

It needs finger like protection as it is used for digestion. So it needs to be curvy.

Mouth(that produces saliva), stomach, gallbladder, pancreas, liver, bowels.

Abdominal pain is ache and discomfort that occurs in your abdomen. Your abdomen area includes the stomach, tummy, gut and belly can. These area can experience pain from time to time. There can be many causes of abdominal pain; lead poisoning, cystitis, appendicitis, aortic aneurysm, pregnancy or many others. Your pain may be mild or severe. If your pain is severe and your pain lasts over a week, contact a doctor immediately.

Epiglottis

some examples of the sphincter muscle are, the anus (not even joking, if we didn't have one there, we would poop our pants without controlling it lol), the intestines, stomach, bile duct, and uterus.

it depends on the nutrients and their size. some nutrients absorb via diffusion, others is facilitated diffusion (needs a carrier protein and no energy), and others are via active transport (needs energy and a protein channel).

The digestive tract (a.k.a: gastrointestinal tract) (a.k.a: alimentary canal) is approximately 20 feet (6.5 meters) in a normal human adult male.

Saliva in the mouth moistens the food, while mastication (chewing) breaks the food into pieces. These enter the esophagus where gravity, the circular action of sliding against smooth muscle, and slight peristalsis moves the food into the stomach. Peristalsis is similar to gentle waves within the muscle walls of the esophagus. Peristalsis only and always moves in one direction: downward. Peristalsis in the intestines is stronger.
gravity my friend. gravity.

When digestive juices and foods are mixed, they form a semi-liquid substance known as chyme. This mixture occurs in the stomach, where gastric juices break down food into smaller particles, facilitating digestion. Chyme then moves into the small intestine, where further digestion and nutrient absorption take place.
