The stomach functions to Group of answer choices dehydrate materials prior to sending them to the next segment of the tract. store food material for later use, as fat. absorb most of the nutrients from foods. primarily break down foods by mechanical means. do all of the above.

The main function of stomach is to serve as a temporary storage chamber and primarily breaks down food by  mechanical means.

Explanation:

The stomach is a muscular organ located on the left side of the upper abdomen.It secretes acid and enzymes that digest food.The stomach muscles contract periodically, churning food to enhance digestion (breaking down of food by mechanical means). The stomach is made up of several layers of tissues

The mucosa (mucous membrane) is the inner lining of the stomach.

Next is the sub mucosa.

The muscularis propria (or muscularis externa) is the next layer that covers the submucosa. It is the main muscle of the stomach and is made up of 3 layers of muscle.

The serosa is the fibrous membrane that covers the outside of the stomach.

The stomach has 3 main functions:

1.temporary storage for food, which passes from the esophagus to the stomach where it is held for 2 hours or longer

2.mixing and breakdown of food by contraction and relaxation of the muscle layers in the stomach

3.digestion of food

The stomach secretes various secretions containing enzymes which breaks down food chemically and the muscles mechanically break down the food.Food is broken down into a thick, acidic, soupy mixture called chyme, which enters the intestine.

primarily break down foods by mechanical means

Explanation:

The stomach carries out both mechanical and chemical digestion of food substances.

it walls are made up of  three layers of muscles fibres; the inner oblique , the middle circular  and the outermost  longitudinal. which collectively are known as the muscularis externa, and the muscularis mucosa  where mucous is secreted, and glands for enzymes. it is guided by two sphincters which prevent food regurgitation into the oesophagus(oesophageal  sphincter), and outlets into the duodenum(pyloric sphincter).

Basically the inner oblique layer   is the actual muscle that conduct mechanical breakdown of food, by churning (stir, shake)the partially breakdown  food substances  arriving  from the mouth. The mucous  softening  the foods substance,  chemical breakdown  by enzymatic process in the stomach  further breakdown the food materials.

Thus when the digesting food leaves the stomach, it has become partially digested, and it is called Chyme. It passes through the pyloric sphincter to reach  the duodenum.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
