This document outlines the key points of a lesson on vacuum suction treatment and the lymphatic system. The lesson objectives are to identify the benefits of vacuum treatment, describe how the machine works and key contraindications, demonstrate treatment on the legs, locate and name lymph nodes, and state the function of the lymphatic system. Key topics covered include oedema, lymphatic drainage, the composition and structures of the lymphatic system, identifying lymph nodes, and the benefits of vacuum treatment for reducing cellulite and fatty deposits. Students will participate in group work to discuss and teach each other about lymph nodes and systems before being directly questioned to check learning.
