- Cells on the skin renew themselves every two weeks.
- The cerebellum, which coordinates our movements, is three years younger than our actual age.
- Eyelashes and eyebrows are also renewed every two months.
- When we donate blood, we lose around 3.5 trillion blood cells, but our body renews itself.
The human body has a perfectly created working order; organs, tissues and cells constantly renew and strengthen themselves, ensuring the continuity of our life. Every day, approximately 150-200 billion cells of many organs that have the ability to renew themselves are renewed.
It is possible to lose a part of our vital organs and live.
The spleen is an organ found in almost all vertebrates. Similar in structure to a large lymph node (lymph node), it primarily acts as a blood filter. The word spleen is derived from the Old Turkic word ‘talak’ meaning ‘love, melancholy’ and ‘an organ, spleen’.
It is a soft organ about the size of a fist in the abdominal cavity, below the diaphragm. It is one of the organs most frequently damaged and removed from the body as a result of injury. Since it is located in an area close to the ribs, it is likely to suffer abdominal trauma. It is surrounded by a paper-like capsule that ruptures easily. This capsule can easily cause internal bleeding if damaged, and if left undiagnosed and untreated, this can result in internal bleeding and death.
The spleen can be likened to a dead end connected to the circulatory system. While the blood travels through the system of large channels and vessels in the spleen, it comes into contact with the spleen cells. The spleen is closely related to blood physiology.
Known functions of the spleen; Production of red blood cells, Production of white blood cells, Destruction of red cells, Blood storage.
A person whose spleen is removed can continue his normal life.
Stomach; It is an expandable digestive system organ composed of muscles. It is located between the esophagus and the small intestine. It functions in the second phase of digestion (following chewing). It is the organ in which food is temporarily stored in large quantities.
The main functions of our stomach are;
It provides digestion of food with its contraction and relaxation action.
It performs chemical digestion by digesting proteins.
It ensures the passage of digested food into the blood by absorption.
It can be surgically removed as a result of stomach, cancer or trauma damage.
In 2012, a British woman had to have her stomach removed after drinking a cocktail containing liquid nitrogen. When the stomach is removed, surgeons connect the esophagus directly to the small intestine. A normal diet can be maintained with a good recovery and vitamin supplementation.
The reproductive organ is any part of the body involved in sexual reproduction. The reproductive organs together make up the reproductive system. The testes in males and the ovaries in females are called primary reproductive organs.
These organs exist in pairs and people can have children by removing one of these organ pairs. One or both reproductive organs can be surgically removed due to cancer or violence, sports and traffic accidents, especially in men. In women, the uterus (uterus) can be removed. Surgery on the uterus (hysterectomy) prevents women from having children and also stops the premenopausal menstrual cycle. Studies show that the average life expectancy of women who have their ovaries removed will not decrease. Interestingly, the average life expectancy may increase for men who have had both testicles removed.
In the anatomy of the digestive system, the large intestine is the part between the small intestine and the anus. Its total length is between 1.5 and 2 meters, and it makes up one-fifth of the digestive tract.
Its main task is to absorb water and vitamins and to compress the remaining nutrient waste pulp and turn it into feces.
Cancer or other diseases can cause part or all of the colon to be removed.
Although it causes a change in toilet habits after surgery, people generally recover comfortably. It is recommended to be fed with soft foods at the first stage to help this healing process.
The gallbladder or bile duct is a small, hollow organ where bile is stored and concentrated before being released into the small intestine. Bile is produced by our liver and aids in the digestion of fats but is stored in the gallbladder when it is not needed for digestion. In our body, the pear-shaped gallbladder is located on the right side of our abdomen, close to the rib cage, just below our liver.
When our small intestine detects fat, it stimulates the gallbladder at the point of releasing bile, with a hormone it secretes to aid in the digestion of fats. However, excess cholesterol in the bile can form gallstones, and these stones can block the small tubes through which the bile circulates. When this happens, the gallbladder may need to be removed.
Gallbladder removal surgery is known as cholecystectomy and it is estimated that 40,000-60,000 people undergo this operation every year in Turkey, although there is no exact data. While many people have gallstones without any medical intervention, not everyone is so lucky. It is known that a woman in India had 12,000 gallstones surgically removed in 2015, a record number.
In human anatomy, the appendix (vermiform appendix) is a closed-ended tube attached to the cecum. It develops embryologically from the cecum. The Latin word “vermiform” means “worm-like looking”. The cecum is the first sac-like structure in the abdominal cavity. It is a small, blunt-ended worm-like structure located at the junction of our large intestine and small intestine.
Due to its unilateral nature, when intestinal substances enter, it becomes difficult to expel and the appendix becomes inflamed. This is called appendicitis or appendicitis. In severe cases, the appendix must be removed. On the other hand, even if your appendix is removed, it can grow back and cause pain. In some cases, a small part of the appendix may remain in the body and this part may become inflamed again. People who have their appendix removed do not feel any difference in their life.
Kidneys are bean-shaped excretory organs in our body. The kidneys, which can be up to 13 cm in length, form part of the excretory system. These organs filter wastes, especially urea, from the blood and discharge them as urine with water. The filtering units inside the kidneys are called nephrons. Each kidney contains about 1 million nephrons.
Many people have two kidneys, but you can survive with one. You can even live without two kidneys depending on the dialysis machine. The role of the kidneys; It is to protect the water and electrolyte balance and the acid-base balance of the body by filtering the blood. Our kidneys do it by acting like a sieve, holding in useful things like protein, cells, and other nutritional ingredients that the body needs. More importantly, it allows us to get rid of many things we do not need through urine.
We may have to have our kidney or kidneys removed for many reasons. Inherited conditions, damage or infection from alcohol and drugs are some of these causes. If we lose both kidneys, kidney function can be provided with the support of an external dialysis machine. In this way, wastes are eliminated from the body.
If a person is on dialysis, life expectancy will vary depending on certain factors such as type of dialysis, gender, existing diseases and age. A study published in Pediatric Nephrology (2017) predicts that patients in their 20s who are on dialysis live 16 to 18 years, compared to about 5 years for people in their 60s.
