Medical Video: Lung Anatomy
Every air that humans breathe and exhale again will not work well without an organ called the lungs. Generally each human has two lungs (right and left), where the lungs are also one of the largest organs in the body.
Usually, the left lung is slightly smaller than the right. Because the left lung must share space with the heart so that it can fit right inside the chest cavity. The lungs and heart are placed close together aiming to work together well, and surrounded by ribs that protect these two important organs.
It is undeniable that the lungs are one of the most important organs in the human body. But how far do you know this organ?
A person can hold his breath for more than 20 minutes
Usually, a person can hold his breath for about 30-60 seconds. Why can't humans hold their breath for long? Basically this limitation is more often caused by the accumulation of carbon dioxide in the lungs.
It's different if you compare with divers who can linger in the water. Divers usually have different breathing techniques, for example hyperventilation. This technique is useful for reducing the buildup of carbon dioxide in the blood, so that it may be when they can hold their breath for quite a long time, about 20 minutes at a single dive.
The lungs are the only organ that can float on water
Did you know that the lungs can float in water? Yes, each of your lungs actually contains around 300 million balloon-like cell structures and is called an alveoli. Alveoli is what replaces carbon dioxide waste in the blood with oxygen. If this cell structure is filled with air, the lungs can be the only human body organ that can float on water.
The medical study examined by the International Journal of Legal Medicine in 2013 stated that there was a medical examination of the lungs as a buoy. This examination is related to the purpose of the baby's autopsy to determine whether the baby is still alive or has died in the womb. If the baby's lungs float, it is certain that the baby in the womb is still alive. But if the lungs do not float, the possibility of the baby being born is lifeless. This method has been done by many doctors, and usually runs 98% accurately from time to time.
Lungs became an important symbol in ancient Egypt
Both humans and animals will not be able to breathe air smoothly without any lung organs. Well, because the lungs are considered to be very important organs, the people of ancient Egypt greatly glorified the lungs.They assume that the lungs have their own relationship to survival. To the extent that they create hieroglyphs (sacred carvings) that depict the lungs and throat to symbolize unity in their country first.
Not infrequently also found a variety of ancient artifacts in the Pharaoh's time, including clothing, furniture, jewelry and carvings of walls that much resemble the shape of the lungs.
