Operation Ouch!: Season 6, Episode 12

6 - 12: Tremendous Tears

Dr Chris makes Dr Xand cry to demonstrate how your body makes different types of tears to protect your eyes in different ways, and in Operation Takeover they discover just how dangerous it can be out at sea when they join the Lifeboat service. Dr Xand investigates how important our facial expressions are, and the hospital wards are bursting with more medical questions in Ouch and About on Call. Meanwhile over in Accident and Emergency one patient has cut her hand with a craft knife and another needs his gnashers fixing after falling at a skate park.
