Breaths of Life

Synopsis: Animals have evolved many different methods for obtaining oxygen from their environment. This programme explores the respiratory challenges of two organisms: the water-breathing crab and the air-breathing bird. Reversals of water flow in the shore crab are shown to provide efficient oxygen uptake under conditions of relative oxygen lack. Also examines the unique anatomy of the avian lung, which enables birds to meet the high oxygen demands of sustained flight.

At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
