VENTRICLES

• WHAT TYPE OF WALLS DO VENTRICLES HAVE?

  thicker muscular walls
• WHY DO VENTRICLES HAVE THICKER MUSCULAR WALLS?

  larger contractions to create higher blood pressure, so blood can flow longer distances (to lungs/ rest of body)
• WHICH VENTRICLE HAS THICKER WALLS?

  left
• WHERE DOES THE RIGHT VENTRICLE PUMP BLOOD TO?

  lungs
• WHAT PRESSURE MUST THE BLOOD IN THE RIGHT VENTRICLE BE?

  lower pressure
• WHY MUST THE BLOOD IN THE RIGHT VENTRICLE BE AT A LOWER PRESSURE?

  prevent capillary damage, slow blood flow, more time for gas exchange
• WHERE DOES THE LEFT VENTRICLE PUMP BLOOD TO?

  rest of body
• WHAT PRESSURE MUST THE BLOOD IN THE LEFT VENTRICLE BE?

  higher pressure to reach all cells, so larger contractions are required
