Sincerely Your, SURF3DMORE INFORMATION ABOUT 3D MODELS :LUNGS ARE THE PRIMARY ORGANS OF THE RESPIRATORY SYSTEM WHICH HELP IN THE EXCHANGE OF GASSES. THE OTHER MAIN PARTS OF THIS SYSTEM INCLUDE A SERIES OF AIRWAYS FOR AIR PASSAGES, BLOOD VESSELS AND THE MUSCLES THAT FACILITATE BREATHING.

THE LUNGS ARE THE PRIMARY ORGANS OF THE RESPIRATORY SYSTEM IN HUMANS AND MOST ANIMALS INCLUDING A FEW FISH, AND SOME SNAILS. IN MAMMALS AND MOST OTHER VERTEBRATES, TWO LUNGS ARE LOCATED NEAR THE BACKBONE ON EITHER SIDE OF THE HEART. THEIR FUNCTION IN THE RESPIRATORY SYSTEM IS TO EXTRACT OXYGEN FROM THE AIR AND TRANSFER IT INTO THE BLOODSTREAM, AND TO RELEASE CARBON DIOXIDE FROM THE BLOODSTREAM INTO THE ATMOSPHERE, IN A PROCESS OF GAS EXCHANGE. RESPIRATION IS DRIVEN BY DIFFERENT MUSCULAR SYSTEMS IN DIFFERENT SPECIES.

The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.
