This page contains an online biology worksheet on the human respiratory system diagram for children to review. This system is responsible for taking in the oxygen we need and expelling carbon dioxide that has been rejected by the body. Breathing in and out carries air to the lungs which get into contact with a surface of cells that absorb it and circulate in it the blood. The main unit in the respiratory system are the lungs. That is why if you are sick of pneumonia from Covid 19, your lungs get affected and you die from suffocation. The latter is caused by the inability for the alveoli to capture the oxygen that gets into the blood.
Due to the rise of air pollution and some bad habits like smoking that some people pick up along the way, our lungs are beginning to suffer from a lot of damage. It is important to live healthy lifestyles to maintain our lungs healthy too.
The lungs play a vital role in the respiratory system and generally speaking, without our lungs, we cannot survive. To learn the anatomy of the lungs easily, play this game until you get all the position of the labels right. This game can be used in the classroom to review this skill or at home to teach children. The human respiratory system quiz, respiratory system diagram and more. Teach children biology in 2nd, 3rd, 4th, 5th, 6th, and 7th grade.
