Can the oxygen diffuse from the blood stream into the intestine through the villus?

Question

then how do we get enough oxygen if all the oxygen is diffuse into the intestine?

Please explain why?

Answer 1

All of the oxygen does not diffused into the intestine-it is wrong.Through the gaseous exchange in the lungs oxigen is atrracted by the haemoglobin and then carried to the various parts of body.The food absobed in the body through the intestine requires oxigen to break down the glucose into water,carbon dioxide and ATP(molecules of energy).Thus,only some amount of o2 is taken by the intesine for its survival.

Answer 2

Um, I think you're a bit confused. Oxygen is taken in from the lungs' alveoli by the red blood cells. Oxygen doesn't travel in the bloodstream on its own. There is no way that oxygen can diffuse into the intestines, because red blood cells cannot go through the villus. The villi is a one-way street. Nutrients go in.

Carbon dioxide, however, travels through in the blood stream as carbonic acid, and is converted into CO2 as it reaches the alveoli so that it can be removed from the body.
