Digestive System

Secretes bicarbonate to make the acid alkaline

It takes around 62 hours for water to pass through, but if its a slightly thicker, liquid it takes around 46 hours.

(The thinner the substance, the longer it takes).

Once food passes out of the stomach, enzymes get to work on the nutrients in the small intestine, breaking them into smaller products. It is also in the small intestine where substances are absorbed into the bloodstream. This absorption takes place in tiny, finger-like structures called villi. These line the walls of the intestine, and are ideal for the diffusion and active transport of molecules.

NO!

the stucture of the circulatory system is to the circulatory - or cardiovascular - system carries blood that is low in oxygen away from the heart to the lungs via veins, where oxygen levels are restored through the air which we breath in; once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive.

It consists of the heart, which powers the whole process; the veins and arteries; and capillaries, which deliver oxgen to tissue at the cellular level.

The process is called peristalsis. It is the rhythmic contraction of smooth muscle cells in the lining walls of your gastrointestinal epithelium. It occurs when you are awake, asleep, etc. and is sped up or slowed down by your nervous and endocrine (hormones) systems. Basically, your internal organs give lots of little squeezes that makes food/what used to be food move along.

the bile duct

chemical digestion takes place in the small intestine large intestine,mouth and stomach. Nutrients are absorbed in the small intestine and minerals in the large intestine.

No. On some individuals, the appendix is very small or may be merged into the surrounding tissue during growth. In a rare condition known as situs inversus, the appendix may be on the left side rather than the right side of the abdomen.

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.

pepsin

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.
