The one part of the human body that does not grow from birth to death is the sclera.

The sclera is the tough, white, outer layer of the eyeball that forms the “white” of the eye. Unlike many other tissues and organs in the human body, the sclera remains relatively stable in size and does not undergo significant growth after early childhood. Its size and structure remain fairly constant throughout a person’s life.

Other parts of the body, such as bones, muscles, and organs, can continue to grow and change in size over time due to factors like aging, nutrition, and physical activity. However, the size and structure of the sclera typically remain constant, with minor exceptions related to conditions like eye diseases or injuries.
