They filter out the food that we eat some keeps the nutrients we eat out of the food and the others get rid of what we don't need.
The mouth.
The oral cavity, most commonly known as the mouth, is surrounded by the lips - which are at the anterior of the mouth, the throat which opens into the pharynx - this is named the posterior of the mouth, the cheeks - these are the lateral borders of the mouth, and finally, the palate, which is located at the top of the mouth. The lower part of the mouth is composed mainly of the tongue and the muscles that surround this, and aid its movement. The tongue is covered with specialised cells, which are named taste buds. They are named as such because of their sensitivity to tastes that enter the mouth.
Surrounding the palate, on the top of the mouth and the tongue below are the teeth. These are set into the gums which are made up of tissue. An adult's mouth should normally consist of thirty-two permanent/secondary, fully developed teeth, whereas a child's mouth would contain a set of 'milk teeth' which the secondary teeth replace.
When food enters the mouth, the muscles of the lips, cheeks and tongue - which form a ring - help to keep the food in the mouth and act as a barrier. The mouth is also lined by a mucous membrane. This membrane is lubricated by the mouth's production of saliva, produced by three saliva glands.
The tongue is a very important part of the mouth. It's a large muscular organ which is attached to the oral cavity at the posterior, the anterior of the tongue remaining free. The thin fold of tissue attaching the tongue to the floor of the mouth is named the frenulum.
Functions of the mouth:
The particular, crucial functions of the mouth are listed below:
· Ingestion and taste: Through the mouth, liquids and foods are taken in to begin the process of digestion - ingestion. During this process the taste buds in the tongue are stimulated by the production of saliva during the following process
· Mastication, commonly named chewing: This is the movement and action of the muscles around the mouth and, perhaps more vitally, the movement of the (lower) jaw which forces the upper and lower sets of teeth to firmly press together. This action makes the food in the mouth break down into very small and easy to swallow pieces which aid in further digestion.
· Digestion: digestion is able to begin to take place in the mouth as of the presence of amylase, the enzyme that breaks down starch, or carbohydrates.
· Swallowing: The tongue's muscular action, that is caused by the will to swallow, forces and shapes the chewed food into a ball, named 'bolus', and also pushes the bolus into the pharynx to be guided on to further digestion.
· Protection: Lubrication of the mouth is provided by the mucin and water contained in the saliva. Also contained in the saliva is the enzyme named 'lysozyme' which kills and destroys harmful microorganisms.
And they help us to eat
Mouth - mechanical and chemical digestion (salivary amylase)
Oropharynx/laryngopharynx/esophagus - none
Stomach - mechanical and chemical digestion (HCL, pepsin)
Duodendum - chemical digestion (bile, trypsin, chymotrypsin, pancreatic lipase)
Jejunum/ileum - absorption
Large Intestine - dehydration and defecation
1.Mouth-to digest food
2. Esophagus-tube that connect mouth to stomach
3.Stomach-gastric juices break down solid food into liquid
4.Large Intestine-undigested material from small intestine moves here before it leaves your body
5. Small Intestine-food is further digested and absorbed here
the function of organs in the digestive system is to break down food
An organ is a collection of tissues working together as a unit. An organ system is a collection of organs performing a common function and working as a unit.
organs are interdependent because they must work together to function, otherwise, we won't work properly. they cannot work alone. organs work together and organ systems work with another to function.
yes
It is hard to state the number of different 'Systems'. Each organ system performs a unique function.
The tissues work together to create an organ. Everything builds from each other. Multiple cells work together to create tissue. Tissues work together to form an organ. Organs work together to create an organ system such as the digestive system. the one who wrote this is a liar
Answer Is an Organ. Such as the Heart or Lungs. Is an organ system.
organ means:a collection of tissues that work together e.g. the heart An organ system is a chain of different organs which each do different things for one purpose. e.g. the digestive system or the respiratory system
cardiovascular - heartdigestive - stomachnervous - brain
An organ is one specific part of your body, it doesn't have to have just one purpose but usually has one main purpose. An organ system is a chain of different organs which each do different things for one purpose. e.g. the digestive system or the respiratory system
Organ system level
what does each part do in the digestive system
No. The collection of organs is organ system.
