Not really "why" answers, but: # food, nutrients, oxygen (or compounds from which oxygen is harvested), and to expell wastes... to permit life. # some organisms transmit nuclear material as part of sexual reproduction. # Diseases organisms such as virus and fungus will also pass through (or chew through) the cell membrane.

How does the intestins work?
Bile and pancreatic enzymes act upon chyme in the duodenum to break food up into there respective monomers. Those are then absorbed through the lining of the small intestine. The nutrients that can be absorbed are absorbed by the end of the small intestine. The large intestine primarily reabsorbs water and forms feces.
What membrane connects the small part of the intestine?
Mesentery.
Does assimilation occur through the small or large intestine?
Through the small intestine
What is the membrane that holds coils of small intestine together in a frog?
The mesentery.
How does the immune system tie in with the small intestine?

The small intestine hold bacteria From the you eat and exiles it through the large intestine, rectum, and anus.

What type of tissue lines the peritoneal cavity of the small intestine?
The visceral peritoneum, a serious membrane, lines the outside of the small intestine where it meets the peritoneal cavity.
What multiplies the surface area of the small intestine?
The folding of the mucosal membrane increases the surface area of your small intestine, thus allowing more nutrients to be absorbed.
How does the villi help the small intestine to absorb sugars quickly?
Surface Area and DiffusionThe small intestine is all about maximizing surface area. The immense amount of folding enables it to be very long meaning more surface area. The villi further increases surface area. They are projections that provide even more membrane surface area that food, while passing through the small intestine, will come in contact with. This contact with the membrane of the small intestine is how absorption occurs. Nutrients that are used in the body will diffuse across the intestinal membrane into the blood stream because the concentration will be high inside the intestine and low in the blood plasma. This difference in concentration is what "drives" diffusion across the membrane.
Primary site for absorption of nutrients?
The Duodenum and Illeum (both parts of the small intestine) through chemical digestion
The main site of alcohol absorption is in the?
small intestine. Alcohol is primarily absorbed into the bloodstream through the walls of the small intestine after it is consumed.
What job does small intestine do?
The job That the small intestine does is absorbs small food particles through micro villi
