This recorded excerpt uses LearnSkill’s existing Human Heart teaching text, its whiteboard and automatic visual-popup components, and an anatomical cardiac-cycle GIF. The English narration was generated with Aarav Sir’s configured voice using ElevenLabs V4. This is a recorded, re-narrated demonstration, not a live call.
The animation is Cardiac-Cycle-Animated.gif by DrJanaOfficial, with the Wiggers diagram derived from Xavax, via Wikimedia Commons.
The animation and this recorded adaptation are licensed under Creative Commons Attribution–ShareAlike 4.0 International. Changes: the heart and complete graph were arranged side by side; English narration and the lesson board were added. No endorsement by the original authors is implied. This license applies to this media adaptation, not the platform’s software.
The US desktop walkthrough is an additional recorded adaptation under the same licence: the original complete lesson frames and narration are retained, with an illustrative Aarav panel added alongside them. Its portrait is a still image, its waveform follows the recorded narration, and its controls are part of the video—not a live call.
