food enters the mouthand is chewed by the teeth by the process of mastication.

Tongue rolls the food into a ball before swallowing called a ...
The food enters the oesaphagus(a muscular tube which transports the food towards the stomach).What is the name of this muscular process?
once past the cardial sphincter(the valve which separates oesophagus from stomach) the food drops into the stomach where gastric acid and enzymes.what is the function of enzymes?
| to break down large insoluble molecules into small soluble ones (by ReRe) |
| to proivde the right enviroment for the food particles to act on (by nushi) |
| They act as catalysts in the breakdown of food into soluble pieces (by caz) |
| catalyse breakdown of large soluble food (by Anon) |
| to imulcify and catalyse the breakdown of large molecules into smaller ones (by Diana) |
| to act as a catlyst, speeding up thebreakdown of large molecules into smaller soluable ones. (by Diana) |
| Break down specific food molecules into smaller ones that can be absorbed into the blood (by Ben) |
| breakdown food (by anna) |
| to break down the food (by Anon) |
| to digest food (by Anon) |
which acid is in the stomach? (It breaks down large pieces of food into smaller pieces).
| protease (by ReRe) |
| hydrochrolic acid (by nushi) |
| amylase protease lipase (by tasha) |
| hydrochloric acid (by caz) |
| hydrochloric acid (by Anon) |
| hydrocloric acid (by Diana) |
| Hydrocloric acid (by Diana) |
| Hydrochloric Acid. It doesn't break down food though, it actually provides and optimum pH for the enzymes to work. And, if your thinking of bile, that is released into the small intestine via the bile duct from the gall bladder (by Ben) |
| gastric acid (by anna) |
| amino acids (by Anon) |
which enzyme is most common in the stomach and which type of food does it break down?
| protease breaks down proteins into amino acids (by ReRe) |
| protease and proteins. (by nushi) |
| protease (by caz) |
| protease (by Anon) |
| carbohydrase- catalyses the breakdown of carbohydrates into glucose (by Diana) |
| protease (by Diana) |
| Pepsin - protein (by Ben) |
| lipase breaks down fat (by Anon) |
| Carbohydrase, it breaks down carbohydrates (by Anon) |
the now smaller pieces of food now past through the pyloric sphincter into a small tube called what?
a special gland and an organ also secretes enzymes and a fluid into this tube.What are their names and what do they secrete?
| gall bladder? (by ReRe) |
| endocrine :S (by nushi) |
| pancreas and gall bladder. bile, protease, amylase and lactase (by caz) |
| pancreas which secretes, amylase,lipase, carbohydrase (by Diana) |
| Pancreas secrets, amylase, lipase protease, carbohydrase (by Diana) |
| Pancreas - secretes amylase, protease and lipase; and also some sodium hydrogencarbonate (weak alkali) - secreted via the pancreatic duct (by Ben) |
| pancreas secretes insulin (by Anon) |
what effect does the enzyme and the fluid do to the food?
| mash it up (by ReRe) |
| speeds up reaction (by nushi) |
| breaks it into soluble pieces ready for absorption in the intestine (by caz) |
| it breaks it down into smaller molecules (by Diana) |
| it imulcifies the particles (by Diana) |
| Breaks it down into smaller molecules for absorbtion (by Ben) |
| breaks the sugar down into glycose (by Anon) |
from this tube the food enters the small intestines where the broken down food is absorbed into the blood stream through billions of tiny little finger like structures called what?
which is the main blood vessel the nutrients are absorbed into ?
From the small intestines any unabsorbed food passes into the large intestines where mostly water and some salts are reabsorbed leaving a waste product called?
