In the video, a person is seen drawing a diagram on a whiteboard. The diagram appears to be related to a cell, with various parts labeled. The person is using a black marker to draw the diagram, and the video is shot from an overhead angle, focusing on the whiteboard and the person's hand. The diagram includes labels such as "HEART," "OUTSIDE," and "Na⁺," indicating different parts or components of the cell. The person's hand moves quickly as they draw, and the video captures the process of creating the diagram from start to finish.
