Exploring the Human Body: Systems and Senses

The video tutorial explains how the human eye and brain work together to process visual information. It covers the anatomy of the eye, including the sclera, cornea, iris, and pupil, and describes how light is focused by the lens onto the retina. The tutorial also discusses common vision problems like nearsightedness and farsightedness, and how they can be corrected. The session concludes with engaging riddles and a teaser for the next lesson.
