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.

Why is the esophagus flexible?
The esophagus is so long because it needs time for food to digest before more food comes in.
How is diffusion important in the process of digestion?
Diffusion is important to the process of digestion, because it allows certain nutrients to enter the blood stream. Glucose and amino acid are able to enter our blood through diffusion after the food has been broken down in the intestine.
How do the respiratory and digestive system remove waste?
the respiratory system doesnt really "remove" waste. instead it uses mucus to catch dust particles and other possible things like pollen.
the digestive system removes waste by "releaseing" it into the world :P
in other words by pooping
Which digestive system organ is the target of gastrin?
Parietal cells in the stomach, which secrete HCl
What are the three enzymes os digestion?
Only 2 enzymes affect the digestion in stomach: 1. Pepsin 2. Rennin the third one is HCl acid which is required for activation of propepsin or pepsinogen which is the inactive form of pepsin and killing of germs that enter along with the food. Also rennin is present only in young ones and is utilized for breakdown milk protein.in adults, this is achieved by pepsin itself. there are not only 3 but many more enzymes involved in digestion.
What is a digestive system with only one opening called?
A digestive system with only one opening is called an incomplete digestive tract. Organisms with this type of digestive system ingest food and eject waste through their mouth.
The process of breaking down large droplets of fat into small droplets of fat is called?
Homogenisation
Right answer is Bile Emulsification that causes breakdown of f at globules.
A substance that increases the solubility of fats to facilitate their digestion and absorption is?
Bile
Like any and every food, if you eat to much of it, then yes, you will gain weight. But if you have toast for breakfast, that's not going to hurt.
What do pepsin and amzlase break down?
Pepsin breaks down the proteins with the help of HCL. Pepsin works quicker nd better when the food is acidic, HCl makes the food acidic and helps pepsin break down Protein in food.
3 ways to keep the digestive system healthy?
extercise, drink lots of water, and eat foods with lots of fiber
In terms of the digestive system and diet, there are many many ways, but three of these would be: Proper intake of water, intake of fibre to ease digestive transit, and monitor salt intake.
Why do people need an appendix?
You don't need appendix. It is a vestigial structure that only might get in your way if it becomes inflamed.
However, recent research shows that it creates helpful bacteria.
- Researchers at Duke University Medical Center say that the function of the frequently discarded appendix, an organ often credited with little importance and often dismissed as having no significant function, does it all;the appendix produces and protects good germs for the gut by "rebooting" the digestive system.
- However the researchers say sometimes the bacteria die off or are purged from the intestines as in diseases such as cholera or dysentery. According to the researchers, the appendix's job is to "reboot" the digestive system when that happens with the bacteria safely harbored in the appendix.
- It was once believed that when the human passed gas it caused the appendix to twist and release bacteria ... but that rumor was dissmissed
- Many doctors believe the appendix is a vestigial organ with no function and is no more than a blind ended tube connected to the cecum, from which it develops embryologically.he cecum is a pouch-like structure of the colon and the appendix is near the junction of the small intestine and the large intestine and has abundant infection-fighting lymphoid cells, which suggests it plays a role in the immune system.
- The most common diseases of the appendix (in humans) are appendicitis and carcinoid tumors. Appendix cancer accounts for about 1 in 200 of all gastrointestinal malignancies.Appendicitis is a condition where the the appendix becomes inflamed and in almost all cases it is removed either by laparotomy or laparoscopy; left untreated, the appendix will rupture, leading to peritonitis, then shock, and, if continued untreated, death. The appendix is routinely removed without any notable ill effects or side effects and the scientists stress that even though the appendix seems to have a function, people should still have them removed when they are inflamed because since leaving it untreated could be fatal.
- Dr. Bill Parker, a professor of surgery and one of the scientists responsible for establishing its status as a useful organ, says the function of the appendix seems related to the massive amount of bacteria that populates the human digestive system and where it is located just below the normal one-way flow of food and germs in the large intestine, helps support that theory.
The study appears in the online edition of the Journal of Theoretical Biology.
Large Intestine
Why is the digestion of food and subsequent absorption into the bloodstream important?
The two primary roles of the digestive process are absorption and secretion. The role of absorption in the digestive system is vital to the body because without it, the vitamins, minerals, carbohydrates and other nutrients we consume could not be used. Absorption is the process by which the nutrients in food are passed on to the blood. The majority of absorption occurs in the small intestine, the digestive tract's primary organ.
After food passes through the stomach to the small intestines, it is turned into energy for the body to use. Absorption is made possible by the villi, small bristle-like protrusions in the mucosa. The mucosa is the moist tissue lining certain parts of the body's passages and organs. The villi act as channels through which the nutrients derived from digested foods can pass into the bloodstream and be carried to the rest of the body. The actual absorptionprocess is slightly different for each type of nutrient.
Do the muscles in the gullet help to push the food down to the stomach?
The mouth chew the food first, a muscle at the back of the mouth forces the food down your gullet and the gullet's muscle forces it down into your stomach.
Yes, all dairy products can. Also spicy foods may trigger acid reflux, as well as chocolate. Stop milk for a while and see if your acid reflux goes down. You may want to ask your doctor about Prevacid it works really well. 35mg-75mg.
What causes food to get stuck in the esophagus?
Food stuck in the esophagus is blocking your airway. If your airway is blocked, no air can get into your lung, thus causing breathing difficulties.
What help the immune system work properly?
Everything helps the organs in the body. Water, food, blood, oxygen and more. Without all of this, the organs wouldn't be healthy.
What attaches to the small intestine and absorbs water?
The small intestines absorb the nutrients out of your food. The stomach leads to the small intestine and the small intestine leads to the large intestine. The large intestine absorbs water, and then the food goes to the rectum.
