1.	Which internal organ needs deoxigenated blood of our body??
Answer» Because the deoxigenated blood returns back from all over the body to lungs for exchange of gasses. So,Lungs are the wright answer.... But its not wright Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.
