where does the gas exchange happen in the body

alveoli

what takes the blood from the right side of the heart to the lungs

pulmonary artery

what is the only artery that carries deoxygenated blood

pulmonary

how many pulmonary veins are there and what do they carry

4

carry oxygenated blood from lungs to left side of heart

what are the lungs made of

parenchyma
