The human body is a complex biological machine consisting of numerous systems that work together to sustain life. It is composed of various organs, tissues, and cells that carry out specific functions to maintain homeostasis. These systems include the nervous, respiratory, cardiovascular, digestive, musculoskeletal, endocrine, and immune systems, among others. The average height of an adult human is about 1.7 meters and weighs around 60-80 kilograms. The body is controlled by the brain, which receives and processes information from the senses and directs the actions of the muscles and organs. Proper functioning of the human body requires a balance of physical activity, a nutritious diet, and sufficient rest and sleep.
Several body organs are vital for our survival and cannot be lived without, while others can be removed or modified without significant harm to the person. Here are some examples:
Organs in the human body are dispensable
1- the Gallbladder is not necessary for digestion
The gallbladder is not essential for the digestion process, as the liver can produce and secrete bile directly into the small intestine to aid in the digestion of fats. However, the gallbladder stores and releases bile as needed, which helps regulate the flow and concentration of bile and enhances the digestion process. People who have had their gallbladders removed can still digest food effectively, although they may experience some changes in their digestion.
The only thing a person who has had their gallbladder removed should do is avoid too many fatty foods in their diet.
2- Can the body function without the spleen?
Yes, the body can function without the spleen. The spleen is an organ that plays a role in filtering the blood, producing immune cells, and storing blood. However, if the spleen is removed or damaged, other organs and tissues can compensate for its loss, and the body can still function normally. However, without a spleen, the body is at a higher risk of certain infections and other health problems, so it's important for people without a spleen to take precautions to protect their health.
3- The appendix is not essential to the human body
Yes, the appendix is not essential to the human body and its removal does not result in any significant long-term harm. The appendix is a small pouch-like structure attached to the large intestine, and its function is not well understood. Some theories suggest that it may have played a role in the digestive process in our evolutionary past, but it no longer serves a vital purpose in the human body. In the event of appendicitis, where the appendix becomes inflamed and swollen, it must be removed to prevent complications. After the removal of the appendix, the body can continue to function normally without any significant long-term effects.
4- One lung is enough to keep you breathing
Yes, one lung is enough to keep you breathing. Although having two lungs is ideal for optimal respiratory function, the body is able to compensate for the loss of one lung. The remaining lung can expand to fill the extra space in the chest cavity and take on the added workload of breathing and oxygenating the blood. However, having only one lung can impact overall respiratory function, increase the risk of respiratory problems, and affect physical activities and exercise capacity. People with one lung may need to make lifestyle adjustments to maintain their health and manage any respiratory symptoms they may experience.
5- Can you omit the colon?
Yes, the colon can be removed, either partially or completely, in a surgical procedure known as colectomy. This procedure may be necessary for several reasons, including colon cancer, inflammatory bowel disease, diverticulitis, and certain hereditary colonic diseases. The remaining portion of the intestines can be reattached to allow for normal digestive function. In some cases, a temporary or permanent colostomy may be necessary, where the end of the remaining intestine is brought through an opening in the abdominal wall to allow for the elimination of waste outside of the body. People who have had their colon removed can still live normal lives, although they may experience changes in their digestive function and elimination patterns.
6- dispense on the urinary bladder
The urinary bladder is a muscular sac in the pelvis that stores urine produced by the kidneys before it is eliminated from the body through the urethra. No, the bladder cannot be dispensed with because it serves an important function in the urinary system by temporarily storing urine until it can be eliminated from the body at a convenient time. The bladder also helps to regulate the flow of urine and prevent incontinence.
But it turns out, like many other members of this list, that the bladder is often (safely) removed from the body when it poses a risk of cancer or inflammatory disorders in a person.
When a person has a cystectomy, they may need to wear a special bag attached to the outside of their abdomen to remove urine. This procedure is called a urostomy, and it works by allowing urine to continually leave the body.
In some cases, the doctor may be able to create a bag using tissue from the intestines that can hold urine after it passes through the kidneys. This urine can then be drained from the body through the catheter without having to pass through the actual bladder.
7- Can food be eaten without stomach?
No, food cannot be eaten without a stomach. The stomach is an essential part of the digestive system and plays a crucial role in breaking down food, mixing it with digestive juices, and grinding it into smaller pieces that can be absorbed by the small intestine. Without a stomach, the food would not be properly digested and the body would not receive the nutrients it needs to function properly. In some medical conditions such as gastrectomy (removal of the stomach), individuals are sustained through alternative methods such as tube feeding or intravenous nutrition.
But a person can survive without a stomach under certain conditions!
8- Tonsil removal
Yes, it is possible to live without tonsils. Tonsillectomy, the surgical removal of tonsils, is a common procedure and most people who have had their tonsils removed go on to lead healthy, normal lives without any significant complications or problems. While tonsils play a role in the body's immune system, other parts of the immune system can compensate for the loss of the tonsils, so living without them is typically not a problem.
9- Can you live without a thyroid gland?
Yes, it is possible to live without a thyroid gland. In such cases, the individual would need to take hormone replacement therapy for the rest of their life to replace the hormones normally produced by the thyroid. Without hormone replacement, a lack of thyroid hormone can cause a number of health problems, including fatigue, weight gain, and depression.
10- You don't need eyes in order to live
That is incorrect. While some individuals are born without eyes or may lose their eyesight later in life, the eyes play a crucial role in enabling individuals to see and navigate the world around them. Without the ability to see, individuals may experience a range of challenges, including difficulty with daily tasks, reduced independence, and a decreased quality of life. While it is possible for individuals to adapt to blindness and lead fulfilling lives, the eyes are necessary for normal vision and play an important role in overall health and well-being.
