Digestive System

Two questions:

Food is broken down in the stomach and small intestines.

Nutrients (plus other related stuff) is carried from the small intestines to the liver via the portal system.

Some nutrients pass directly from the liver to the veins (inferior vena cava),

then is carried by the blood to the rest of the body.

Other chemicals are modified by the liver into useful compounds, then are also dumped into the vena cava for distribution.

Human saliva is composed of 98% water, while the other 2% consists of other compounds such as electrolytes, mucus, antibacterial compounds, and various enzymes. As part of the initial process of food digestion, the enzymes in the saliva break down some of the starch and fat in the food at the molecular level. Saliva also breaks down food caught in the teeth, protecting them from bacteria that cause decay.

Yes bacteria produces enzymes used, in the fermentation process of making vitamins.

Also bacteria makes Vitamin K and two B vitamins, niacin and thiamine. NOW STOP BEING FRIKIN LAZY AND DO YOUR FRIKIN HW!!!!!!!!!!

well, females have two large intestines because one is for the growing child inside. however, Sim-biotic intestine systems in females are common in indigenous communities of northern uzbeckastan.

Lysosomes

The usual first step is to drain away any residue from the ruptured appendix, and treat with antibiotics to prevent infection. Then they will remove it.

They would remove it right away if it had not yet burst.

yes because every living thing eats and plants are living so they do digest.

After food gets absorbed and you get all of the nutrients you need from the food, the rest turns into waste and that`s where all of the number 1`s & 2`s come into play.

Indigestible Plant Parts Dietary fiber can be soluble, such as pectin, or insoluble, such as cellulose.

I think it is the Stomach, Salivary Glands, Pancreas, Small Intestine

yes, after food is digested excess water or leftover watre is reabsorbed by the large intestine. Certain types of vitamins are also synthesiszed here, people who do not go to the wash room after long periods of time tend to have constipation because water is reabsorbed from the feces.

The cell contains ribosomes which produce proteins, and the nucleus contains DNA which codes for proteins. They can work together to produce particular proteins called enzymes which are used to digest food.

Each cell also contains lysosomes which digest any microorganisms within the body. Lysosomes also destroy old organelles in the cell which are no longer needed.

When large molecules are broken down they actually turn into a different substance. Proteins break down into amino acids. Lipids break down into fatty acids. Carbohydrates break down into simple sugars. And those are just a few of them. Large molecules need to break down so that they can change into other substances so they can dissolve or help the body another way.

Food is digested in the stomach, and this digestion continues to some degree in the small intestine. But it is largely in the small intestine that the nutrients are absorbed from the stream of digested materials. Anything not absorbed continues on to the large intestine for water extraction and further on to excrement.

The small intestine.

The mouth mashes food with the teeth and mixes it with saliva which also includes some acid compounds.

Technically speaking, never, as long as you hold it. There are 2 types of muscles protecting you from urinating.

1. Smooth muscle that is involuntary. Excess or certain amount of urine present in your urinary bladder relaxes this muscle involuntarily.

2. Skeletal muscle that is voluntary. You can control this hence why you can hold the urine from coming out. However, you are consistently aware of this, because it is voluntary and you're voluntarily holding it. This muscle is absent in young children, hence the "accidental" urination. As you grow older, you also acquire some control of your bladder.

Problem is, when you hold your urine or feces too long, you might get really really sick. Examples are infections and kidney failures. These leads to death, especially in the case of kidney failure.

The mouth breaks the food into small fragments which lead tot the stomach which digests its, then passes the food down to the small intestine which turns it into leftovers, or commonly known as poop. (awks)

The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. Inside this tube is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food.

Two solid organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes. In addition, parts of other organ systems (for instance, nerves and blood) play a major role in the digestive system.

When undigested waste passes too quickly through the large intestine, not enough water is absorbed resulting in Diarrhea. Likewise, when too much water is absorbed the result is constipation. We just learned this in my 8th grade Science class. : )

Digestion is accomplished by physically breaking down, or chemically breaking down foods.

The pH level must rise

it contains enzyme amylase which digests starch,and a lubricant which makes food slippery and easy to swallow

The purpose of the digestive system is to break down food to make it absorbable into the bloodstream.

The liver breaks down subtances such as Alcohol, Drugs and any other waste material so that the kidney's can remove them. The liver also destroys old red blood cells.
