   We get the oxygen to our cells with the respiratory system and by breathing. Breathing In. We breathe in using a muscle called the diaphragm. It flattens out making our lungs expand and fill with air. When we breathe in, air gets forced through our nose or mouth, down our windpipe, and into bronchi tubes in our lungs.

   Gas exchange system - The human gas exchange system is a group of organs that work together to enable us to breathe. Pressure - The molecules of a gas in a container collide with the walls of the container and this creates pressure. Volume - The volume of a gas is the amount of 3D space it fills. Inhalation - Breathing in is called inhalation.

   What type of respiration does a human body use?

   • Human bodies use both types of respiration. Humans do aerobic respiration unless they are short of oxygen when they switch to anaerobic respiration. Tiny parts of cells floating in the cytoplasm where energy is released from glucose. The glucose comes from food. The liquid that makes up most of the cell in which chemical reactions happen.
