Answer:
The air begins to enter the body through the mouth or nose, passing quickly to the tubular cavity (throat), through the speech organ (voice box), into the trachea, that branches into the left and right cartilaginous tube at intervals the lungs and divides into smaller and smaller branches referred to as bronchioles. littleest|the littlest|the tiniest} bronchioles find yourself in small sacs of air, referred to as alveoli, people who enter whereas respiration, and reduce throughout respiration.
The shift of gas is that the delivery of gas from the lungs into the blood, likewise because the elimination of greenhouse gas from the blood to the lungs. It takes place within the lungs between the alveoli and a network of little blood vessels referred to as capillaries, that square measure found on the walls of the alveoli.
The walls of the alveoli really share membranes and capillaries wherever gas and greenhouse gas move freely between the systema respiratorium and therefore the blood flow. gas molecules attach to the red blood cells, that travel back to the guts. At an equivalent time, the greenhouse gas molecules within the alveoli explode out of the body through subsequent breath.
