Science homework (The Gas Exchange System)
By 16leighk, Updated
Homework for science Friday session 1.
Air particles (in this case Jackson) enters our body through your mouth or nose when you breath in.
Jackson then travels down the trachea/ windpipe and decides which lung to go down... It's a hard decision!! Next, Jackson needs to move down the bronchus (which is any of the major air passages of the lung). He moves through the bronchioles after this, into an alveolus (an air sac).
The oxygen from Jackson then diffuses into the blood, running all around the body to keep you going! Then you breath back out the waste, the carbon dioxide.
