ATS GCSE Biology - Structure of the heart & circulation Key words Diagram

• pulmonary artery


  blood vessel that takes deoxygenated blood heart right ventricle to the lungs

  
• vena cava


  large vein that brings deoxygenated blood body into heart (right atrium)

  
• left hand cardiac muscle

  thicker than the right hand sideto pump blood to the entire body

  
• right hand cardiac muscle

  thinner than left hand side

  
• simple circulation


  heart, lungs, heart, rest of body

  
• circulation

  vena cava, right atruim, right ventricle, pulmonary artery, lungs, pulmonary vein, left atrium, left ventricle, aorta, organs, vena cava

  
• ventricles


  chambers of the heart that contract to force blood out of the heart

  
• atria


  the upper chambers of the heart

  
• double circulatory system

  the right ventricle pumps blood to the lungs where gas exchange takes placethe left ventricle pumps blood around the rest of the body

  
• heart


  an organ that pumps blood around the body in a double circulatory system
