Digestive System

Digestive System is the category for questions regarding the breakdown and absorption of food-stuffs in our alimentary canal. Questions about the stomach and intestines can be included in this category.

What are chewing and churning types of?

Chewing and churning are types of mechanical digestion. The other type of digestion is chemical digestion, which involves the breaking down of foods via enzymes.

What cause your body to dump food after you eat?

Something called the gastrocolic reflex causes your intestines to move everything forward a bit when the stomach is stretched.

If you eat tomato and after digestion tomato skin remains undigested will this cause disease?

Not at all. Undigested tomato skin will pass harmlessly through the digestive system, and causes no disease.

Since your stomach contains hydrochloric acid will your esophagus and mouth get corroded when you vomit?

No, unless there is chronic emesis as associated with anorexia or bulimia. Because it is acidic, there is a good Chance you will experience irritation or burning.

How do individual cells digest food?

specialized organelles called lysosomes digest food in the cell...

What is the medical term meaning outpouching through the muscular layer of the intestine often associated with the sigmoid colon?

A diverticulum (plural diverticuli) is an outpunching through the muscular layer of the intestine. The condition of having diverticuli is diverticulosis, and inflammation of one or more of the outpouchings is diverticulitis.An abdominal, ventral, or inguinal hernia, in contrast, is the abnormal outpouching of the intestine or other organ through a weakness of the abdominal wall.

Benefits of eating meat?

Healthy lean meats are a great source of protein, iron (red meat), and other essential micro nutrients. The amino acids from meat differ from the amino acids available in vegetable proteins.

Meat gets a bad reputation from eating lots of fatty cuts too often.

Like everything else moderation is the key.

A wide variety of macro and micro nutrients from all the food groups is the key to good health and health issues

What are the types of digestion?

Chemical digestion and mechanical digestion

What must occur so food can pass though the wall of the alimentary canal?

For food to properly pass through the alimentary canal, digestion must first occur. The process of moving food through the alimentary canal is called propulsion.

How does food passes through the digestive system?

how food travels through your digestive system is first it goes through your esophagus second it goes through your stomach third it goes through your small intestine then last it goes to your large intestine

What happens if your digestive system stops?

Digestive system consists of many organs; both large and small. Different organs have different functions and hence, play their part when necessary.

Now if the digestive system was to stop working, then the organs taking part in the digestion process should stop working as well. Here are the list of organs along with their major functions during in digestion:

> Mouth [chewing],

> Salivary glands [lubrication of food],

> Oesophagus [transportation of bolus from mouth to stomach],

> Lungs [metabolism; oxygen from lungs helps in the breakdown of food materials/ bolus],

> Stomach [major digestion point],

> Liver [produce digestive juices],

> Pancreas [produce enzymes],

> Gall Bladder [bile production],

> Small Intestine [major food absorption],

> Large Intestine [water absorption and excretion of solid waste materials],

> Rectum [let the person know about the evacuation of stool and holding it till evacuation],

> Anus [control of stool evacuation with the help of sphincter muscles]

So basically, if the digestive system was to stop working, then the above given organs along with some other (unmentioned) organs have to stop as well. The result might be horrifying.

But a logical result will be choking, hormones deficiency, loss of weight, thirst, imbalance in immune system, etc and maybe more graver conditions.

In the digestive system where are stools formed?

Formed stools are made as the digested food waste travels through your intestines. They take the shape of your bowels and colon through which they pass. As the liquids are absorbed into your body and peristalsis compacts the waste, the shape is formed.

What is the difference between intracellular and extracellular digestion?

Intracellular = inside the cell.

Extracellular = outside the cell.

Digestion = chemical breakdown of matter into components that the body can use.
.
- Intracellular- food is broken down when it is in the cell (engulfed by phagocytosis), nutrients are absorbed.
Done by sponges
- Extracellular- food is broken down (with help of enzymes?) before nutrients are absorbed by/into cells.
Done by most mammals, simple animals (such as flat worms) have a gastrovascular cavity, more complex mammals (such as humans) have an alimentary canal.
In humans is takes place in different compartments (stomach, small intestine).
Extracellular dig. allows mammals to consume larger prey.

Is the planaria digestive tract complete or incomplete?

Mammals have a complete digestive tract, it starts from mouth to anus. Although each species have some different type and length of tract, they have esophagus, ventriculus, intestinum which function to support a complete food metabolism. Besides, some digestive glands also support this function.

What are five ways that you could prevent a chemical change in food?

I know three if that helps. You could refrigerate or freeze it. You could add salt to it. Or you could use antioxidants.

What causes white foamy throw up?

If it's foamy like shaving cream and all white, it might be rabies unless you haven't been bitten by anything strange, but that happened to me too. I ate an egg and it was 1 week old, i didn't feel good for about 2 hours, then i threw up white slimy transparent "goo" that looked like saliva.

Why is it good to have digestive glands attached to intestines?

So that the intestines can digest the food more easily and more quickly than usual. I am 100% sure that this answer is right because I got it out of my science book, called Science Fusion book 2. I hope that this will be helpful for you! (:

Is it true that in the stomach proteins and fats are first digested?

Proteins are the last to be digested. Fats and sugars are among the first.

carbohydrates get digested in the mouth by saliva

then the proteins in the stomach by an enzyme called pepsin

then fats in the very beginning of the small intestine by an enzyme created by the liver and stored in the gall bladder that enzyme is called bile
