Not every part of your body is essential for survival. In fact, the human body is remarkably adaptable. Here are 10 internal and external body parts that people live full, active lives without.
One Lung

Even though we have two, you only need one to live a mostly normal life. The remaining lung expands and compensates for the missing one. You might struggle with intense exercise, but everyday activities won’t be affected much.
One Kidney

Plenty of people donate a kidney or lose one due to illness and continue to live healthy lives. The remaining kidney adjusts to handle all the filtering work. With regular check-ups and attention to blood pressure, most people don’t notice the difference.
Stomach

If the stomach is removed due to disease, the esophagus can be connected directly to the small intestine. Eating habits change, but life goes on. Smaller, more frequent meals and some vitamin supplements are usually enough to adapt.

Small Intestine

Losing parts—or in rare cases, most—of your small intestine affects digestion. However, many people manage with diet changes and supplements. The rest of the digestive system steps up to make it work.
Colon

If the large intestine is removed, stool is redirected through a surgically created opening into a colostomy bag. While this takes adjustment, most people live full lives, work, travel, and even play sports without major issues.
Reproductive Organs

People can and do live without reproductive organs. Testicles, uterus, or parts of the vagina are sometimes removed for medical reasons. Hormonal balance can be maintained, and sexual function can still be a part of life.
Thyroid Gland

The thyroid regulates metabolism and growth, but people can live without it by taking synthetic thyroid hormones. With proper dosage, symptoms disappear, and energy levels and body functions stay on track.

Spleen

If the spleen is damaged or ruptured, it can be removed. Other organs take over its role in fighting infection, though you may need extra vaccines and should be alert to illness, especially shortly after surgery.
An Arm or a Leg

Many amputees lead active, independent lives. With modern prosthetics and adaptive tools, losing a limb doesn’t mean losing quality of life. People ski, climb, and work in every profession imaginable.
Eyes

Blindness doesn’t stop people from living fully. With enhanced hearing, touch, and technology like screen readers and guide dogs, those without sight navigate the world in amazing ways every day.
