The appendix may be the most commonly known useless organ. Many years ago, the appendix may have helped people digest plants that were rich in cellulose, Gizmodo reported. While plant-eating vertebrates still rely on their appendix to help process plants, the organ is not part of the human digestive system.
Appendix. The appendix is perhaps the most widely known vestigial organ in the human body of today. If you've never seen one, the appendix is a small, pouch-like tube of tissue that juts off the large intestine where the small and large intestines connect.
You'll be surprised as to how much you could lose and still live. You can still have a fairly normal life without one of your lungs, a kidney, your spleen, appendix, gall bladder, adenoids, tonsils, plus some of your lymph nodes, the fibula bones from each leg and six of your ribs.

The skin, bone tissue (including tendons and cartilage), eye tissue, heart valves and blood vessels are transplantable forms of tissue.
Answer: The eyeball is the only organism which does not grow from birth. It is fully grown when you are born.
Altogether there are seventy-eight main organs within the human body. These organs work in coordination to give rise to several organ systems. Among these 78 organs, five organs are considered vital for survival. These include the heart, brain, kidneys, liver and lungs.
Organs that can be donated by living donors
Kidneys are the organs most frequently needed, followed by livers. Both of these organs can be donated by living donors to save someone's life. 85% of people awaiting a transplant need a kidney. A kidney is the most commonly donated organ.
The skin is the largest organ of the human body.
If you have both kidneys completely removed, you will not make any urine. You will need to have kidney dialysis. This is a way of getting rid of waste products and excess water that the kidneys normally filter out of your blood. Dialysis means you can lead a more or less normal life without a working kidney.
Transplanted Organs Don't Last Forever
Meanwhile, a liver will function for five years or more in 75 percent of recipients. After a heart transplant, the median survival rate of the organ is 12.5 years. A transplanted pancreas keeps working for around 11 years when combined with a kidney transplant.
Intestine. Small intestine transplantation is the rarest type of solid organ transplant. Currently, approximately half are pediatric recipients.
That fluid and the tissues connecting them are called the interstitium (pronounced "inter-STISH-um"), and they're found throughout the body, both just below the skin and in the digestive, respiratory and urinary systems.
You can comfortably live without a spleen. This is because the liver plays a role in recycling red blood cells and their components. Similarly, other lymphoid tissues in the body help with the immune function of the spleen.
Although some patients who have a diseased portion of their liver removed are unable to regrow the tissue and end up needing a transplant.
The 11 organ systems include the integumentary system, skeletal system, muscular system, lymphatic system, respiratory system, digestive system, nervous system, endocrine system, cardiovascular system, urinary system, and reproductive systems.
What makes up the integumentary system? Your integumentary system is an organ that consists of a few main structures: skin, nails, hair and glands, along with the nerves and blood vessels that support them.
It takes 3 years from seed to harvest for asparagus to grow, but in an ideal climate it can grow up to 10 inches in one day! What about white asparagus? White asparagus is not genetically induced but instead gets its color due to the absence of sunlight, meaning it is grown in the dark!

While the rest of our body shrinks as we get older, our noses, earlobes and ear muscles keep getting bigger. That's because they're made mostly of cartilage cells, which divide more as we age.
The brain and nerve cells require a constant supply of oxygen and will die within a few minutes, once you stop breathing. The next to go will be the heart, followed by the liver, then the kidneys and pancreas, which can last for about an hour. Skin, tendons, heart valves and corneas will still be alive after a day.
Within hours, blood is pulled downwards, causing splotches on the skin. Because the heart is no longer pumping blood around the body, it starts being pulled down by gravity. As the blood pools, patches appear on the skin within 30 minutes of death.
The first organ system to “close down” is the digestive system. Digestion is a lot of work! In the last few weeks, there is really no need to process food to build new cells. That energy needs to go elsewhere.
