How does the mouth helps to digest food?
One part of your body that many people forget are your teeth. They are very important to your health. Many people use chemical products to support their teeth because they believe that these chemical ingredients are some sort of instant teeth whitener. The best solution for healthy teeth is to use plant-based, natural products. They are ecologically made and give the best, natural needs to your teeth for amazing dental health.

What is the job of the tongue in the digestive system?
The teeth break down the food into smaller pieces for easier digestion.
The tongue mixes the food with saliva to break it down further, and also pushes the food down your throat so it can travel down the esophagus.
In chemical digestion are foods physically broken down into smaller pieces by chewing?
Chemical digestion is the process of enzymes and acids breaking the bonds that make up the food. Proteins are broken down into their chemical components by enzymes. Chewing is the mechanical process, aka as mastication, which cuts and grinds the food into smaller particles that are mixed with saliva to form a ball-shaped mass or bolus. The saliva contains an enzyme analaise, which starts the first stage of chemical digestion. This enzyme breaks the long carbon chemical chains that make up starches into simpler compounds called sugars.
The "slimy" bolus then travels down the esophagus through the pyloric valve into the stomach. Here, the strong muscular stomach, together with the hydrochloric acid churns the chyme, mixing it with the acid and the bolus is further reduced in size and chemical complexity. The resulting food-stuff is now called chyme.
What product of digestion is not normally released directly into the bloodstream?
The product of digestion is not normally released directly into the bloodstream is fats. Fats have to be broken down by the liver.
The products of digestion that is not normally released directly into the bloodstream is fats. On the other hand, carbohydrates, minerals and vitamin C are digested and released directly into the bloodstream.

Whats wrong bleeding from rectum with back and abdominal cramps?
Not a pregnancy symptom, go to the doctor
The muscular system uses the bones for their action. Without bones muscles would be useless at distance. Bones act like lever arms to increase the force produced by muscles. The digestive system gives nutrients to the muscles.
Enzymes inside lysosomes digest what?
Lysosomal digestion is the use of lysosomes (enzymes contained in vesicles) to break down substances that enter a cell by endocytosis. Usually the substances they break down are harmful to the cell.
In which organ of the digestive system does bile work on fats?
Bile is an emulsifier, which means that it breaks lumps of fat up into droplets. This increases the overall surface area of the fats, so there is more room for enzymes to work on breaking it down into smaller products.
How do the esophagus work with other organs?
The esophagus works with other organs by bringing the food down to the throat and to the stomach. From the stomach to the intestine's, and through the Colan and thats the process! I hope it helped.
Thick soupy food mixture in the digestive system?
The mixture of partially digested food and gastric juices is called chyme.
Can appendix be located on left side?
The appendix is located on the left hand side for children under three.
You breathe in air through your lungs. This air travels to the alveoli in your lungs. There are capillaries in your alveoli. The oxygen in the air gets absorbed by the body while the waste product (CO2), gets expelled from your body. The digestive system breaks your food down into a substance small enough to be absorbed by the body. Glucose which is one substance the food is broken down into travels, as well as the oxygen, through the circulatory system to the cells. The oxygen and glucose react in the cells to make energy.
That is how they all work together.
------------------------------------------------
Just to reword that answer:
When you breathe in air (inhale) you are also breathing in oxygen. That oxygen travels down into your lungs and into small air sacs called alveoli. These small air sacs are surrounded by capillaries carrying oxygen-poor blood. This blood has carbon dioxide in it which is a waste product produced during cell activities.
Now, when this oxygen is in your alveoli the oxygen diffuses through the thin membranes of the alveoli into the surrounding capillaries. Then the carbon dioxide from the blood in the capillaries diffuses into the alveoli. When you exhale the carbon dioxide in the alveoli are released into the air. That was the respiratory part--now the circulatory system comes into play.
That blood which is now oxygen-rich needs to be circulated throughout the body because your body cells need the oxygen to perform its cell activities. And so, blood is transported through the capillaries to the many cells in your body. These capillaries do not only circulate oxygen rich blood-it also circulates glucose. After cells use this oxygen and glucose and carbon dioxide is released as a waste product into the blood. That blood is brought to the lungs through the superior and inferior vena cava, into the right atrium, through the right ventricle, through the semi-lunar valves, and into the lungs. It is here where the oxygen-poor blood full of carbon dioxide becomes oxygen-rich with the help of the alveoli and such.
Here we come to a full close between the respiratory and circulatory system.

Where does the greatest amount of nutrients absorbed take place?
Even though some digestion takes place in the mouth (starch) and the stomach (protein), it is actually the small intestine where most of the food we eat is broken down, and also where virtually all the absorption occurs.
Does the protein digestion begin in the stomach and is it completed in the small intestine?
Yes. The digestion of protein begins in the stomach with the enzyme pepsin and ends in the small intestine using enzymes secreted by the pancreas. Once the enzymes have broken the proteins into their amino acids, they can then be absorbed by the epithelial tissue lining the small intestine.
How long does it take for your stomach to break down food?
It depends if you eat a lot in a little amount of time, normally 20 to 25 minutes if you eat a lot, but 10 to 15 if you don't eat too many snacks in one amount of time.

How long does it take for a mushroom to digest?
Our bodies have trouble digesting cellulose also known as dietary fiber, which is a major component of mushrooms. In some instances mushrooms are not fully digested.
How long do you have to wait after eating to shower?
Digestion requires good blood flow and digestion generates heat. If one takes a warm shower, does exercise or goes for a swim, the blood needs to be diverted to the skin surface for cooling purposes. This interferes with digestive process and you can end up having a stomach ache, can faint or even have a heart failure if you are weak.
Though most people would see no ill effects having showered right after a meal, but weak or old people can have a different reaction. So a healthy habit is to wait for about 30 mins after a meal before taking a shower.
The reason someone would faint would be because there is not enough blood flowing to the brain. Digestion requires a high percentage of blood and when you take a warm shower the blood vessels dilate in order to cool down the body by releasing the heat from blood to the skin. More blood flows through those vessels and since so much blood is being used elsewhere the brain may be lacking blood and the bodys reaction to this is to faint because fainting will keep the body level and the blood will flow evenly. This may not affect a lot of people but people with health concerns and also people with bad circulation may have problems.
What acid is involved in human digestion?
One role of acid in the process of digestion is to neutralize enzymes. Pepsin and hydrochloric acid are released into the partially digested food which helps to break it down even further before moving into the intestines.
Does the pancreas manufacture enzymes to digest all energy-yielding nutrients in the diet?
Yes. It also produces nucleases and proteases.
What cell contains digestive enzymes for breaking down things?
i think u mean the process of catabolism wherethe cells are broken down from complecated (forgot the word) to a simple (same word as the one forget)usualy realesing energy im tacking this stuf in 9th grade igcse and wasent in the mood to check my copybook trust me i got a 22 out of 25
