According to information from the provided reference, the question as posed, asking specifically about an "organ," doesn't precisely match the terminology used in the reference. However, the reference directly answers which body parts never stop growing.
Based on the reference from Vinmec:
Which two body parts never stop growing?
The two body parts mentioned that continue to grow throughout life are the ears and the nose.
Did you know: 2 body parts that never stop growing? Those two parts are the ears and the nose, and it's also strange that both of these parts are located on the head.
While not internal "organs" in the typical sense, the ears and nose are external body structures primarily composed of cartilage, skin, and other tissues. The continued growth is often attributed to the gradual stretching and loosening of the skin and soft tissues, as well as the continued production of cartilage throughout a person's life, although at a much slower rate than during childhood.
- Ears: Cartilage within the ears continues to divide and develop. Gravity also plays a role, causing the ears to lengthen over time.
- Nose: Similar to the ears, the nose's cartilage continues to grow and change shape. The skin and soft tissues also contribute to changes in appearance as aging occurs.
Therefore, when considering body structures that grow forever, the reference highlights the ears and the nose.
