Digestive System

Sperm only has a short life once it is released through the penis. It is kept fresh by the semen it travels in until it reaches the fallopian tubes. If released outside the body it soon dries out and dies quickly.

The terms that apply are "ingesting" and "eating" rather than tasting, which may not involve food, or biting, where the food may not require chewing. The broader term "consuming" has other meanings, but the process of consuming food is called "feeding."

Food moves the digestive system through the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. Solid food waste is expelled through the anus, at the end of the digestive tract.

Hydrochloric acid.

So nothing can go backwards and get stuck.

...

It also maintains the diffusion gradient if food is moving in one direction so the products of digestion are absorbed faster.

small intestine

Most people only have one bowel movement every day or so. Having more than one might be normal for you, but if it's very runny or odd colored or in any other way unusual, you probably should see a doctor to find out what's wrong.

Starch doesn't digest saliva. The enzyme in saliva digests starch.

It is broken into small pieces of food and digested by the digestive juices.

The food goes right through the digestive system from one end to the other, and is egested in the faeces.

The digestion of food starts in the mouth where it is masticated. Saliva is added to form a bolus. This is the start of chemical digestion. Salivary Amylase breaks downs carbs. Food then goes down oesophagus ito stomach where digestion continues. The stomach muscles churn the food with hydrochloric acid and lubricates it with mucus. This then forms a substance called chyme. The hydrochloric acid deactivates salivary amylase and neutralises bacteria. There is a lot more to it but just remember that it starts in the mouth.

The nutrients found in milk are digested by many different enzymes. Lipase acts on the fat molecules, while proteases break down protein. The main carbohydrate in milk is lactose, which is digested using the enzymes lactase.

There are two types of digestion: mechanical (such as chewing), and chemical (involving enzymes.) Enzymes are protein-based, biological catalysts that are specific to a particular molecule. Protease enzymes, for instance, break down proteins, while lipase enzymes digest lipids. Each enzyme has a region called the active site. It is the active site that makes enzymes specific to just one substrate, due to its unique shape. The molecules attach to the active aite, and are broken down. Once the nutrients are digested into their end products, they are small enough to be absorbed into the bloodstream.

It makes it hard to digest food when you are dehydrated.

They are mostly comprised of acidic things not unlike the acid in your stomach. The chemicals in the remedies help break down the food or help you excrete the food. Stay notorious and keep asking questions to make WikiAnswers the best it can be! :D >^

"What's the first step in digesting food? Believe it or not, the digestive process starts even before you put food in your mouth. It begins when you smell something irresistible or when you see a favorite food you know will taste good. Just by smelling that homemade apple pie or thinking about how delicious that ice cream sundae is going to taste, you begin to salivate — and the digestive process kicks in, preparing for that first scrumptious bite. If it's been a while since your last meal or if you even think about something tasty, you feel hungry. You eat until you're satisfied and then go about your business. But for the next 20 hours or so, your digestive system is doing its job as the food you ate travels through your body. Food is the body's fuel source. The nutrients in food give the body's cells the energy and other substances they need to operate. But before food can do any of these things, it has to be digested into small pieces the body can absorb and use. During the process of absorption, nutrients that come from the food (including carbohydrates, proteins, fats, vitamins, and minerals) pass through channels in the intestinal wall and into the bloodstream. The blood works to distribute these nutrients to the rest of the body. The waste parts of food that the body can't use are passed out of the body as feces."

gall bladder

The esophagus is the food passageway posterior to the larynx.

It could limit the amount of food you can eat at one time.

Regurgitation or vomiting is the return of solids and fluids from the stomach back to the mouth.

Most protein digestion occurs in the stomach. However, further digestion of proteins also occurs in the small intestine.

The job of the digestive system is to break your food down,physically and chemically using the good bits I.E vitamins,carbs and stuff to help your body and excrete the bits it doesn't need.
