Which Part of the Human Body Does Not Grow from Birth to Death?
Throughout the course of human life, our bodies undergo remarkable changes. From infancy to adulthood, we experience spurts of growth as our muscles, bones, and organs develop. However, there is one part of the human body that remains the same size from the day we are born until the day we die: our eyes.
The human eye is a marvel of nature, and its growth is completed in the womb. The eyeballs of a newborn baby are approximately 65% of their adult size, and they continue to grow until the age of about 2. Once the eyeballs reach their full size, they remain that size for the rest of our lives.
The reason why the human eyes do not grow after infancy is due to the fact that the eye is a closed system. The eyeball is surrounded by a tough, fibrous layer called the sclera, which prevents it from expanding or contracting. Additionally, the fluid that fills the eyeball, known as vitreous humor, is a gel-like substance that does not change volume.
As a result of these factors, the human eye is able to maintain a constant size throughout our lives. This stability is essential for maintaining clear vision, as any changes in the size of the eyeball could lead to refractive errors such as nearsightedness or farsightedness.
