Human Body Systems - Coggle Diagram

- - - - Functions: has tiny hairs that trap dirt and dust from inhaled air; the part where air enters and leaves the body
    - - Function: connects the nose to the lungs
    - - Function: site of gaseous exchange; oxygen is absorbed into the blood while blood is removed from the blood into the lungs
    - - Function: increase the surface area of the lungs for gaseous exchange between the air in the lungs and the blood to take place more quickly
  - - - A chemical process whereby digested food is broken down in the presence of oxygen to release energy to be used by cells for supporting life processes
      - Occurs in all living cells
      - chemical equation
        
        glucose + oxgen --> energy + water + carbon dioxide
    - - A physical process whereby air is taken into the body (inhalation) and air is removed from the body (exhalation)
      - Occurs at the nose
      - Process
        
        Inhalation
        
        Ribcage moves upwards and outwards
        
        Diaphragm contracts and moves downwards
        
        Size of chest cavity increases
        
        Air from the surroundings enter the lungs through the nose
        
        Exhalation
        
        1.Ribcage moves downwards and inwards
        
        Diaphragm relates and moves upwards
        
        Size of chest cavity decreases
        
        Air in the lungs is forced out of the lungs through the nose
      - Differences between inhaled air and exhaled air
        
        Inhaled air is warmer than exhaled air and vice versa
        
        Inhaled air contains more dust particles than exhaled air and vice versa (some dust particles are trapped in tiny hairs of the nose)
        
        Inhaled air contains more oxygen than exhaled air and vice versa
        
        Inhaled air contains less water vapour than exhaled air and vice versa
        
        Inhaled air contains less carbon dioxide than exhaled air and vice versa
        
        Inhaled air contains the same amount of nitrogen as exhaled air
    - - A physical process whereby oxygen is absorbed into the blood and carbon dioxide is removed from the blood
      - Occurs at the lungs
