The Function and Composition of the Eyes
The podcast explores the complex structure of the eyes and how they are made up of various tissues and specialized components. The eyes are optical devices responsible for delivering images to the brain. They consist of the cornea, iris, pupil, lens, retina, and vitreous humor. Each of these parts plays a crucial role in vision, from allowing light to enter the eye to converting light into neural signals that the brain can interpret. The eyes also have tear production, which helps keep the cornea lubricated, removes foreign objects, and enhances vision. Tears are made up of water, electrolytes, proteins, oils, and hormones.
