Answers
Answer:
2) Your small intestine also breaks down food using enzymes made in your pancreas and bile from your liver. The small intestine is the "work horse"' of digestion -- while food is there, nutrients are absorbed through the walls and into your bloodstream.
3) During digestion, your pancreas makes pancreatic juices called enzymes. These enzymes break down sugars, fats, and starches. Your pancreas also helps your digestive system by making hormones. These are chemical messengers that travel through your blood.
4) Ruminants (e.g. cows, deer, goats, antelope, bison, buffalo, moose, giraffe, elk) have a specialized stomach for fermentation, which requires that they chew, regurgitate and chew their food (cud) again. We humans don't do this (thankfully!). (By the way, our digestive differences start in the mouth.
5) The teeth that are behind the bicuspids are called molars. There are three molars: the first molar, the second molar, and the wisdom tooth. These are the teeth that grind food so that it can be swallowed. Your teeth also start the digestive process with help from saliva and your tongue.
