Could chemical digestion take place if mechanical digestion did not occur?
Mechanical digestion, i.e. your body breaking up the food into smaller pieces, is largely meant to speed chemical digestion up. We know that the rate at which the chemical reaction takes place is dependent on four things: the physical state of the reactants involved in the reaction, the temperature at which the reaction takes place, the concentration of the reactants, and the presence of a catalyst. Each influences the rate of reaction in different ways. Mechanical digestion breaks the food into smaller pieces, i.e. changes the physical state. With the larger pieces broken into smaller ones, more surface area is exposed. With greater surface area exposure, chemical digestion can take place much more rapidly. However, if for some reason you could get just huge chunks of food down your throat without chewing it, your stomach still churns (mechanical digestion) and the contractions in your intestines also help to break up food. So technically yes, chemical digestion would take place, but at a much slower and inefficient manner.
What other location other than the mouth is responsible for majority of mechanical digestion?
The intestines do most of the digestion: if too much of the intestines are removed the person dies.
Is the epiglottis a chemical digestion or a mechanical digestion?
None, because it does not digest anything. It just makes swallowing (w/ saliva) and eating much easier for us, so we do not have the choke everytime.
Where does maximum digestion of food takes place in a vertebrate alimentary canal?
In the small intestine for many mammals, though it's much more complicated in ruminants and hindgut fermenters such as rabbits.
How does mechanical digestion in the small intestine occur?
Mechanical digestion involves breaking down food molecules without changing the chemical nature of the molecules in the food. No chemical bonds are broken in mechanical digestion. Tearing forces (e.g. teeth) or muscular movements (e.g. the stomach) can assist mechanical digestion. Chemical digestion, which requires enzymes, involves breaking the bonds within food molecules and thereby producing products that are chemically different from the substrate (reactant). The smooth muscle layers of the small intestine are not set up for mechanical digestion. There are only two layers of smooth muscle in the muscularis externa of the small intestine: an inner circular layer and an outer longitudinal layer. These two muscles are ideal for peristalsis. In the stomach, however, there is an additional third layer in the muscularis externa (an oblique layer). These three layers can move the contents in the stomach around in many different directions. The stomach, therefore, is much better suited for mechanical digestion.
What organ is the major site of chemical digestion of food?
The digestion (and indeed absorption) of all nutrients occurs in the small intestine. To be precise, it is the duodenum where much of the breaking down takes place. It is here where enzymes from the pancreas, as well as bile from the liver, and secreted, to aid the process of digestion.
Much of the digestion that occurs in the large intestine is caused by?
The digestion that occurs in the large intestine is mainly caused by the action of gut bacteria. These bacteria help break down and ferment undigested food particles, producing essential nutrients and gases like methane and hydrogen. This process also plays a role in the absorption of water and electrolytes.
What take place in the stomach?
Your stomach performs both mechanical and chemical digestion. The stomach is a muscular sac that physically squeezes food about three times per minute. It also secetes enzymes and acid that chemically digest food particles.

How communication takes place?
In cellphones, communications takes place via radio waves to a satellite, or via an underground cable network.
What is the power output of the human heart?
The mechanical power of the human heart is ~1.3 watts. It takes a much higher rate of energy turnover (~13 watts) to provide this mechanical power, since the mechanical efficiency of the heart is very low (less than 10%).
What is the advantage of extracellular digestion over intracellular digestion?
extracellular digestion enables and animal to digest much larger prey then intracellulary digestion allows.
