The topics covered within these lessons include: The need to transport substances Surface to volume ratio Gas exchange at the alveoli The structure of blood and its function The structure of blood vessels The structure of the heart Aerobic and anaerobic respiration All of these lesson presentations and accompanying resources are detailed and How does high surface area to volume ratio affect the function of the mitochondria? window.__mirage2 = {petok:"brXo77COPtjKanuBo40B_9YT11I1eVImbhy4tMQqLEc-3600-0"}; Diffusion For example, when the cube doubles from a length of 1 cm to a length of 2 cm, the surface area increase by a factor of four, going from 6 cm2 (1 cm x 1 cm x 6 sides) to 24 cm2 (2 cm x 2 cm x 6 sides). Diffusion occurs when molecules in an area of higher concentration move to an area of lower concentration. It contains the following sections: Posting Packages Wrapping Presents Bin Bags Rug Rolls Shed Building Decorating School Rooms Swimming Pools Surface area to volume ratio is simply an object's surface area divided by its volume. Nanofiber is a class of nanomaterials with diameters ranging from tens to hundreds of nanometers with high surface-area-to-volume ratio and good flexibility, which makes them uniquely suitable for . 100+ Video Tutorials, Flashcards and Weekly Seminars. 8.3 Be able to describe how alveoli are adapted for gas exchange by diffusion between air in the lungs and blood in capillaries Find my revision workbooks here: https://www.freesciencelessons.co.uk/workbooksIn this video, we explore what is meant by the surface area to volume ratio of an organism. Surface Area to Volume Ratio - Biology | Socratic If you are a cell like the largest cube, your SA:V has become so small that your surface area is not large enough to supply nutrients to your insides.

This nearly ancient formula is still the easiest way to determine the surface area of a sphere.
