As part of their science topic, Primary 4 were treated to a talk by Mrs Swinney and Mrs Purves on the respiratory and cardiovascular systems.  The children were able to ask lots of questions about the heart and lungs.  They also got the chance to look at a model heart, listen to their heartbeat with a stethescope and check their pulse with a monitor.  The children are enjoying their  journey in discovering more and more about the major organs of the human body.
