Is peristalsis chemical digestion or mechanical?
It's mechanical. Peristalsis includes muscles moving material through the digestive system.
Yes
How would non secretion of saliva affect the digestion of food?
The non secretion of saliva would affect the digestion of food because the salivary glands secrete more than just saliva.. they secrete enzymes like salivary amylase which breaks down starch into sugar.. and the saliva also holds he food together and makes it easier for the food to move down the food pipe.
IF ANY OF THE MT PPL ARE LOOKING AT THIS.. THIS IS SOMEONE FROM XVAC..:)
How much time does it takes to digest Maggie?
The time it takes to digest instant noodles, like Maggi, typically ranges from 2 to 3 hours in the stomach, but the complete digestion process can take longer, around 24 to 72 hours, depending on individual factors such as metabolism and overall diet. Instant noodles are low in fiber and nutrients, which can slow down the digestive process compared to whole foods. Individual variations, such as hydration levels and digestive health, also play a significant role in digestion time.
You don't. It makes a substance that helps carry oxygen through your body.
Glad 2 Help :)
What is the tongue used for in the digestive system?
The tongue pushes down food (already moistened by saliva) into the Oesophagus.
How does saliva change food in the mouth?
saliva softens the food so it is eazier for you to break down into small peices
What system works with the digestive system?
It works with the circulatory system because nutriants , vitamins, and food follow through our blood
What parts of the body are responsible for mechanical digestion?
The teeth (in the mouth) - for chewing, and the muscles around the gut - for peristalsis.

What organ absorbs the digested food into the blood?
The small intestine absorbs digested food into the blood.
Small intestine is where 90% of nutrients are absorbed.
Which body system is primarily responsible for extracting nutrient from the food you eat?
the metabolism extracts energy from food
What digestive system structure has villi?
Villi belong primarily to the small intestine of the gut.
It is here that most of the food needs to be absorbed into the body proper for use by it. However, absorption best occurs across a very large surface area where food molecules are in direct contact with the walls of the lining through which they must pass for the body's use.
Villi are countless long projections of the intestinal wall [somewhat like thick hairs, but made of body tissue itself] projecting into the intestine itself that effectively create a surface area of the intestinal wall that is many times greater than it would otherwise be if the wall was sheer and the projecting villi did not exist.
In this way, nutrients find their way far more efficiently into the body proper for use.

Why does it take so long to digest soda?
because of all the things in it. Like caffeine the sugar and preservatives etc. your body has to take out all of the "waste" and that's why it takes forever unlike water which normally goes right through you if you're not dehydrated.
Soda takes very little time to go through your digestive system because it has very little substance to it. It is almost completely water, sugar (carbohydrates), and flavorings and color.
What statement best describes extracellular digestion?
large insoluble molecules are converted to small soluble molecules outside the cell
What are the five organs that are used digestion?
I think they are the stomach, the oesophagus, large intestine, small intestine and mouth?
last 1 I'm not sure about (oesophagus is the tube it goes down)
In which abdominopelvic quadrant would the pain of appendicitis most likely be felt?
You mean "pain in your appendix," but that's okay.
In most people, the appendix is in the lower right portion of the abdomen, but this is not 100%... it can instead be on the left in some individuals, though this is rare.
Which part of digestive system largely absorb water?
The large intestine, also called the colon. It is possible to live without it, going through 3 surgeries (you also have the option to only get the first surgery) and having an ileostomy/colostomy. When you don't have a colon, it is a good idea to drink at least 64 oz. of water each day, to keep from dehydration, as it is very easy to get dehydrated without a colon.
Which system helps produce voluntary movement circulate blood and move food?
The various types of muscles which belong to the muscular system.
I don't know if its the MOST difficult but, sweetcorn has to be up there. I've done a lot of work down the sewers and the amount of sweetcorn that is down there is unbelievable.
What type of chemical reaction takes place during digestion of food?
- digestion of food starts in buccal cavity. saliva contain an enzyme "salivary amylase" or "phylin" which digest 30% carbohydrates into sugar.
- no digestion takes place in pharynx and oesophagus. food reaches into the stomach where gastric juice is secreted which consist of mucus, HCL and pepsin. pepsin break down protein into peptones.
- now the food enters into small intestine. here three juices are secreted - 1. bile juice - contains no enzyme for digestion but its bile salt play an important role in emulsification of fat. 2. pancreatic juice - it contains - pancreatic amylase - remaining carbohydrate gets digested into sugar , lipase - for digestion of fat into fatty acids and glycerol , trypsin - for digestion of peptones into amino acids. 3. intestinal juice - contains intestinal amylase for complete digestion of carbohydrates into glucose.
- the unabsorbed food is sent to large intestine where villi absorb water from the undigested food. the undigested food is then removed from the body via anus.
How long is the food in the digestive system?
It depends on the type of food you are eating and what is in it. Carbohydrates are processed fairly quickly but fats and proteins can take several hours to be digested.
That is a reason people feel that when trying to lose weight, you should eat less carbohydrate foods (bread, cakes, cookies, fruits, pulpy vegetables) and eat more food with fat and protein such as fish, chicken,meats)
Is the major role of the stomach digestion?
No. The stomach absorbs no food, but rather breaks it down into smaller pieces via mechanical digestion and chemical digestion. Long story short, once it travels into the jejunum and the ileum (aka the small intestine) then nutrients are absorbed.
