The video starts with a close-up of a human digestive system, which is colored in shades of blue, green, and red. The camera then zooms out to reveal a full-body silhouette of a human figure with the digestive system highlighted in the same colors. The background is a plain, beige color. The word "digestive system" is written in black text above the figure. As the video progresses, a clock appears on the right side of the frame, and the hands of the clock move in real-time, indicating the passage of time. The clock has a black frame with white numbers and hands.
