Tnx sir now i have no doubt about this chapter special y about the eye part once again thank you❤😢

[@ishowmeme25]

home work: Cornea: The transparent front part of the eye that covers the iris and pupil. It helps focus light into the eye. Iris: The colored part of the eye that regulates the amount of light entering the eye by adjusting the size of the pupil. Pupil: The black circular opening in the center of the iris that allows light to enter the eye. Lens: Behind the iris, the lens helps focus light onto the retina. It can change its shape to adjust the eye's focus. Retina: The innermost layer at the back of the eye that contains light-sensitive cells (rods and cones). It converts light into electrical signals that are sent to the brain through the optic nerve. Optic Nerve: A bundle of nerve fibers that carries visual information from the retina to the brain. Vitreous Humor: The clear, gel-like substance that fills the space between the lens and the retina, helping to maintain the eye's shape. Sclera: The white, tough outer layer of the eye that helps protect and maintain the eye's shape. Choroid: A layer of blood vessels between the retina and the sclera that nourishes the retina. Ciliary Muscle: The muscle that controls the shape of the lens, allowing the eye to focus on objects at different distances.
