Why doesnt food enter the body until its absorbed into the blood?

First think of your digestive tract like a garden hose, if it worked like that you would get no nutrition.
In the real world there are things happening like chewing and saliva.
Saliva is a digestive juice almost as potent as stomach acid, it breaks down the food you chew prior to entering your stomach.
Your stomach pummels the food with digestive juices before it is allowed to enter the intestines.
Fluids are easily absorbed from your mouth as well as your entire digestive tract by capillary actions (you can get drunk from a alcohol enema).
Well this is my simple minded Idea of kinda what takes place.

What is the process in which hazardous materials travel through body tissues until they reach the bloodstream?
Unfortunately there are different ways that each different types of material does this and as there are many different types of hazardous materials, I don't have space here to list them.However here are a few:mercury vapor - inhaled to lungs and absorbed into the blood theremercury liquid - usually does not enter blood to detectable levelsradon gas - inhaled to lungs and decays to solid elements, deposits in lungs and does not enter bloodpesticides - generally absorbed through the skin then into the bloodgasoline, kerosene, etc. - generally not absorbed into blood, the hazard here is mostly firecarbon monoxide - inhaled to lungs and absorbed into the blood theresulphuric acid, nitric acid, lye, etc. - chemically burns tissues, does not get a chance to enter bloodcyanide - can enter body by many ways; inhalation, ingestion, skin contactmustard gas - blisters any tissue it contacts (e.g. skin, lungs, nose and throat, genitals) and usually does not enter blood to significant levelsnerve gasses - see pesticidesetc.
What organelle would be missing in a mature red blood cell?
Then the mature red blood cell becomes a useless cell without any knowledge on how to do its job. It will then float through your blood stream until it is absorbed.

Why does food not enter the body until it is abdorbed into the blood?
Food must be digested before it can be absorbed because it is necessary for our digestive enzymes to combine with the food. Once the enzymes combine with the food, our bodies can absorb the nutrients.

Where does the energy from the sun that is not used go to?
Most radiant energy is absorbed by Earth. The rest is reflected and bounces back and forth between Earth's surface and the clouds until absorbed.
How does diffusion take place in digestive systems?
In mammals diffusion occurs at 2 places in the respiratory system. The first place it occurs is in the lungs. The carbon dioxide from the blood diffuses into the lungs and the oxygen in the lungs diffuses into the blood. The second place where diffusion occurs is at the cell. Carbon dioxide diffuses out of the cell and into the blood whereas oxygen diffuses into the cell from the blood. Glucose is also diffused from the capillary to the respiratory cells, since they need energy to function properly. Remember that diffusion works in a certain way: Molecules in a highly concentrated area will naturally diffuse into an area with lower concentrations of that particular substance, until eventually all of the molecules of that substance are evenly spread out within that area.
