In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication (chewing), a form of mechanical digestion, and the wetting contact of saliva. Saliva, a liquid secreted by the salivary glands, contains salivary amylase, an enzyme which starts the digestion of starch in the food; the saliva also contains mucus, which lubricates the food, and hydrogen carbonate, which provides the ideal conditions of pH (alkaline) for amylase to work. After undergoing mastication and starch digestion, the food will be in the form of a small, round slurry mass called a bolus. It will then travel down the esophagus and into the stomach by the action of peristalsis. Gastric juice in the stomach starts protein digestion. Gastric juice mainly contains hydrochloric acid and pepsin. In infants and toddlers gastric juice also contains rennin. As the first two chemicals may damage the stomach wall, mucus is secreted by the stomach, providing a slimy layer that acts as a shield against the damaging effects of the chemicals. At the same time protein digestion is occurring, mechanical mixing occurs by peristalsis, which is waves of muscular contractions that move along the stomach wall. This allows the mass of food to further mix with the digestive enzymes.

Let's be honest. The Internet is quite possibly one of the best and worst inventions to come around in a long long time. With it, you get the good and inevitably, you get the bad. It can help make you more productive in life and it can also cause you to be highly inefficient. Now, before we get off on a rant here I should clarify, this article is actually going to be about free colouring pages. How you may ask? Well, the way I see it, free colouring pages epitomize how the internet can help parents. And although it may sound like a stretch, I'll attempt to connect the proverbial dots that add up to my colouring pages conviction.

But most of all, you will provide your kids with a fun-filled, colorful period of time, which they will enjoy to the fullest extent possible. You will be able to see the sense of pride and achievement in their eyes, which they are bound to feel on the completion of each of these little projects. Coloring pages are a complete entertainment package for kids, especially if you find ones which depict their favorite character, season or theme. Some instances are Pokemon coloring pages and Disney coloring pages. And lastly, aside from all the great amount of happiness, education and satisfaction that these coloring pages will provide to your kids, you are sure to agree when I say that they will give you some amount of time to lay back and relax, instead of chasing your kid around the house for various reasons. They will also help maintain a great, friendly rapport between the two of you, and will be a fun activity altogether, whether on an individual basis, or a collective one.

She's a real icon for Disney and has appeared in many video games and is a regular sight at their many theme parks. Her mischievous ways and expressive face makes her an adorable little character. And what little girl wouldn't want to be a fairy, flying around and having fun? Maybe this is why she is so popular with girls of all ages. When it comes to Coloring Pages for girls, Tinkerbell is one of the most popular. Her well known yellow hair and green dress are very easy to color in and once you add some yellow twinkle dust everywhere, you are well on your way to being finished. Encourage your child to use their imagination and ask them what they think Tinkerbell is up to, or even get them to add in a background to the picture or maybe create a new pet for Tinkerbell. Creativity and use of imagination is one of the many benefits to Coloring Pages.
