Please help me! Explain why oxygen molecules in the tissues of the lung go into the blood, and then in other tissues the oxygen molecules leave the blood.



Answer :

The oxygen in you lungs are of a higher concentration than it is in your blood This process is through the use of passive transport.Your blood is then returned to the heart and pumped throughout the body. Because your blood has more oxygen in it than your cells do the blood through the use of passive transport again give the oxygen to the cells.
