The blood gets the nutrients and the gases from the capillaries in the small intestine.
It will drop of oxygen and pick up carbon dioxide from the cells that make up the tissues of the intestines. Simple sugars, amino acid and some salts and vitamins are also picked up. Some of these are transported to the liver and some through the lymphatic system. Both systems will drop off these to the blood for transport into the entire body.
It shouldn't. The cells are to close together so the blood shouldn't fit through....if it does, it can mean something is wrong
Digestion is completed and absorbed into the bloodstream
Probably what happens in every other part of the body, due to osmosis and dispersion, the oxogen goes out of the blood and nourishes the cells. Meanwhile the Carbon dioxide attaches to the hemoglobin and is carried back to the lung to be exhaled.
the unabsorbed food in the small intestine passes through the ileocecal valve to the large intestine where, after the last few nutrients and fluids are reabsorbed, it is defecated.
Blood passes through the capillaries, which provide a passage way for the blood from the arteries to the veins. The tiny, thin walled capillaries also allow for the exchange of gases through the tissue. You can read more about capillaries at fi.edu
Blood passes through capillaries as a means of either passing products to the cells or picking up things from the cells. The small intestine is where most digestion takes place so the capillaries pick up digested material to take to the liver via the portal system. The digested fat is picked up by the lymph capillaries, lacteals, which returns to the blood when the lymph connects to the right and left subclavians.
When the food is in the large intestine, the majority of the remaining water is absorbed into the blood stream. It then passes into the rectum and anal canal, where it is excreted through the anus.
Oxygen passes from the blood into organs through the wall of capillaries.
It goes into the large intestine and then into the excetory system
There is an exchange with oxygen, nutrients, and carbon dioxide and water vapor.
