Answer:
3)The number of times a person breaths in a minute is called breathing rate.
4)The respiratory system is the network of organs and tissues that help you breathe.
5)The major function of mucus is to protect the lung through mucociliary clearance against foreign particles and chemicals entering the lung.
6)Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water).
7)Inspiration is the process of taking in of the air and expiration is the breathing out of the air.
8)The air that we breathe in enters the nose or mouth, flows through the throat (pharynx) and voice box (larynx) and enters the windpipe (trachea).
9)The left lung is a little smaller than the right lung because it shares space in the left side of the chest with the heart.
10)The fine hair present in the nasal cavity trap dust and other particles in the air you inhale and sweep it out again.
