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.
While you can't live without your liver, you can live with just part of it. Your liver is the only organ in your body that can regrow after parts of it have been removed or damaged. In fact, it can grow back to its full size in just months.
We all know that you can survive with only one healthy kidney; you can also do without your appendix. Which other organs do you not need to be alive? One of your lungs, spleen, gall bladder, adenoids, tonsils, some of your lymph nodes, the fibula bones from each leg, ribs.
Vestigial organs are parts of the body that once had a function but are now more-or-less useless. Probably the most famous example is … the appendix, though it is now an open question whether the appendix is really vestigial.
Some studies suggest that as ancient humans were predominantly herbivorous, they used their appendixes for digestion. However, as humans evolved, they started to include more easily digestible food in their diet and the appendix eventually lost it function.
8. The body as a whole may be dead, but certain parts within are still alive. The brain is the first organ to begin to break down, and other organs follow suit. Living bacteria in the body, particularly in the bowels, play a major role in this decomposition process, or putrefaction.
Even today many of the most popular surgeries involve the wholesale removal of body parts—the appendix, gallbladder, tonsils, uterus (usually after the childbearing years)—with an assurance that patients will do just fine without them.
Unicellular animals have no organs like Amoeba. Further animals belonging to phylum Porifera have only loosely aggregated cells and animals belonging to phylum Coelentrata have tissue systems and hence no organs.
Anatomy & Function
The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.
Only five organs — the brain, heart, liver, at least one kidney, and at least one lung are absolutely essential for living. Losing total function of any one of these vital organs spells death.
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.
You can live without a large intestine - something that comes as a shock to many people. The large intestine or colon has one primary role, water and electrolyte absorption to concentrate the stool. It plays little role in metabolism and people can live full lives without their large intestine.
Severe oxygen deprivation can cause life-threatening problems including coma and seizures. After 10 minutes without oxygen , brain death occurs. Brain death means there is no brain activity.
Types of Organs in a Human Body
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.
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.
The liver has a unique capacity among organs to regenerate itself after damage. A liver can regrow to a normal size even after up to 90% of it has been removed.
Even when vascular collapse is the primary event, brain and lung functions stops next. The heart is the last organ to fail. The heart stops following PEA, but PEA is not cardiac arrest. The heart finally stops when it arrives at asystole, which is cardiac arrest (Figure 1).
Visions and Hallucinations
Visual or auditory hallucinations are often part of the dying experience. The appearance of family members or loved ones who have died is common. These visions are considered normal. The dying may turn their focus to “another world” and talk to people or see things that others do not see.
Acute kidney failure can lead to loss of kidney function and, ultimately, death.
Congenital absence of the vermiform appendix is very rare in human beings with a reported incidence of 1 in 100,000 cases.
Don't worry about going through life without an appendix. People live healthy lives without it. Once you've had your appendix taken out, you should feel a lot better. If your appendix has ruptured, it may take you longer to recover.
If appendicitis is not treated, the appendix can burst and cause potentially life-threatening infections. Call 999 to ask for an ambulance if you have abdominal pain that suddenly gets much worse and spreads across your abdomen. These are signs your appendix may have burst.
