Molecules that can pass through the wall of the small intestines are products that are broken down from starch, lipids and protiens.
Starch breaks down into maltose which is then further broken down into glucose, which is absorbed by the intestine.
Lipids break down into glycerol and fatty acids, which are absorbed by the intestines.
Protiens break down into amino acids, which are absorbed by the intestines.
Vitamins are minerals are alos absorbed by the intestines.
Water is also absrobed by the small intestines, but is also absrobed by the large intestines.

Does intestinal bacteria have a cell wall?
no
What must the molecules in a capillary enter before they enter the cell?
Molecules traveling within the bloodstream pass through the capillary cell wall via osmotic pressure and diffuse through the interstitial fluid before encountering the tissue cell wall.
Why do sugar molecules not diffuse through a plant cell membrane?
The membrane is semi-permeable. Sugar molecules are too large to diffuse through.
Why cant big molecules pass through wall guts?
The cell walls of the intestinal cells do not allow the passage of large molecules through them; in addition, the tight junctions between the cells blocks the transfer of large molecules through the interstitial space.
In Osmosis does salt diffuse through a membrane?
Yes
What lymphatic organ prevents bacteria from breaching the intestinal wall?
Bacteria are prevented from crossing the intestinal wall by the integrity of the intestinal cells, particularly the tight junctions, as well as the mucus lining of the intestines. If bacteria make it into the interstitial space in the intestinal wall, there is a strong diffuse immune system presence in the form of the GALT (gut associated lymphatic tissue) that can quickly move to eliminate trans-locating bacteria. However, there is no specific lymphatic organ, just a collected of lymph nodes and lymph tissues.
How do monosaccharides exit the intestinal cell wall into the capillaries?
Injested carbohydrates are broken down through saliva and the stomach into smaller fragments called mono saccharides, or simple sugars. These sugars are transported to the absorptive cells in the lining of the stomach, where they are in, exit, then passively diffuse into the adjoining capillaries.
How do you resive oxygen and remove carbon dioxide?
Oxygen and carbon dioxide are moved to and from body tissues via the circulatory system. These materials diffuse through the cell membrane, and then diffuse through the capillary wall into or out of the bloodstream.
How does a hookworm effect a human?
Hookworms live in the intestines and suck blood from the human host through the intestinal wall.
Does intestinal bacteria have a cell wall?
no
Which group of fats are absorbed pass through the intestinal cells and diffuse into capillaries and thus directly into the blood stream?
Water-soluble glycerol and short and medium chain fatty acids.
What is a roundworm's food?
blood from the intestinal wall
What is the abnormal dilation in the intestinal wall?
Diverticulosis
Projection on the intestinal wall are called?
villi villi
What kind of reflection does a brick wall cause?
Diffuse reflection
What substance will diffuse through a membrane?
The three substances that can diffuse through a cell membrane are CO2, O2, AND H2O.
If a beam of light falls on a smooth wall will you observe regular reflection or diffuse reflection?
It will be diffuse reflection. No matter how smooth the wall looks it is rough on a microscopic scale and will scatter the light.
