Oxygen enters the blood stream through the air sacs in you lungs.
Nutrients enter the blood primarily through the small intestine. After food is broken down in the stomach, nutrients are absorbed through the lining of the small intestine and into the bloodstream. From there, the blood carries these nutrients to different parts of the body where they are used for energy and growth.
The small intestine
Nutrients leave the gut and enter the bloodstream through the lining of the small intestine.
Blood low in oxygen enters the right atrium of the heart through the superior and inferior vena cava.
In air breathing animals, oxygen enters the blood stream through the alveoli, tiny sacs in the lungs. In water breathing animals oxygen enters the blood stream through the gills.
no...the only thing that absorbs through the stomach is alcohol. everything else absorbs in the intestinal tract.
The nutrients of food are absorbed at the intestine from where they reach the organs and tissues through the circulatory system.
