This resource guides a-level biologists through gas exchange of single-celled organisms with a focus on how terrestrial organisms such as insects also achieve this. Adaptations of an insects tracheal system are explored. Stretch, challenge and lateral thinking questions are embedded throughout.

This resource guides a-level biologists through the need for exchange surfaces in multicellular organisms and how they are adapted for this purpose. A worked example of calculating surface area to volume ratio is included to see how this changes as an organism increases in size. Stretch, challenge and lateral thinking questions are embedded throughout. This is a resource been made to be picked up and used by any teacher.

This resource guides a-level biologists through gas exchange of boney fish. The structure of the gills is explored whilst explaining how the counter-current flow system of gas exchange optimises the diffusion of oxygen. Stretch, challenge and lateral thinking questions are embedded throughout.

This resource guides a-level biologists through how terrestrial organisms such as plants and insects have to balance gas exchange with water loss. Insects and plants adaptations to this problem are explored and discussed in more detail. Stretch, challenge and lateral thinking questions are embedded throughout.

This resource guides a-level biologists through gas exchange in the leaf. The idea of compensation point is dicussed to get students thinking about the dynamic level of gas exchange taking place in a leaf before we explore its structure and how it meets the requirements of gas exchange. Stretch, challenge and lateral thinking questions are embedded throughout.

This resource guides a-level biologists through the need for a gas exchange system in mammals before exploring the macro to the microstrucure of the lungs. The lungs, trachea, bronchi, bronchioles and alveoli are discussed. Stretch, challenge and lateral thinking questions are embedded throughout alongside carefuly selected visuals.

This resource guides a-level biologists through the mechanism of breathing including an in depth discussion about the processes of inspiration and expiration. The calculation of pulmonary ventilation is also discussed. Stretch, challenge and lateral thinking questions are embedded throughout alongside carefuly selected visuals
