Without our body functioning 24/7, we would not be able to survive.Even though we are living and breathing creatures, it’s surprising that we know very little about our bodies. Most of us would be pretty scared if something were to happen to our bodies, even for a single day.Have you ever wondered how the internal organs of the human body have to work constantly? This includes everything from the five vital organs even to a minute organ such as the gallbladder. As an average person, our limited knowledge about the human body is often the reason for us panicking even with the slightest headache. Hence, we thought of coming up with this guide to let you know some fun facts about the human body. We hope this will make you sympathize with the organs and appreciate their work.So, keep reading to know fun facts about the human body system.If you enjoyed this article, why not also read about facts about the Earth’s crust and facts about Mercury, here on Kidadl.Define Body System With One ExampleA simple and easy way to define our body system with one example is to say that our body behaves like a factory.Often you will hear people define the human body as a factory, and it’s quite true. When you think about it, our body is a huge factory where there are different interconnected departments that have to work together to keep us alive. Multiple systems have to work together in the human body to keep us alive. For instance, the respiratory, the nervous system, and the circulatory system work together to help you breathe and pump blood. And, all these take place without you noticing about it. On top of that, our immunity system is always on standby to do emergency care against any intruder that might harm our bodies. Similarly, our digestive system has the responsibility of processing the food to get the essential nutrients that are in turn needed to fuel the other systems with the help of sugar. And, as you might know, when one system begins to fail, our body does try to overcompensate or take its place. However, at the same time, when one system is under threat, the other systems can become vulnerable.One of the most neglected systems has to be the excretory system. That’s why there has been a considerable rise in kidney diseases worldwide. Even though it may seem like a trivial system, without the excretory system, your body can be overpowered with toxins that can shut down the other systems. On top of that, the excretory system plays a vital role in upkeeping skeletal health by taking away the waste material.One of the key roles of all the human body systems working together is to maintain homeostasis or balance, just like between the departments on a factory floor. When there is a serious threat to homeostasis, your body can lose control over itself, similar to what is seen in patients with AIDS. Even though it specifically affects the immunity system, the patients are prone to respiratory infections and even yeast infections.Major Types Of Body System In Human BodyThe human body has 11 major body systems, including the nervous system, respiratory system, circulatory system, digestive system, excretory system, muscular system, skeletal system, integumentary system, lymphatic or immune system, endocrine system, and reproductive system.Even though it’s hard to pick and choose between the organ systems present in the human body, by far the one that’s most crucial for survival has to be the nervous system. You might have heard that doctors do their best to keep the human brain alive in case of a critical situation as it’s the one that controls the other organ system. But, it’s closely followed by the importance of our circulatory system that consists of the heart and has the work of operating the blood supply to every corner of our body. If the heart stops pumping blood or the arteries are unable to make the oxygenated blood reach a certain part of your body, then it can quickly degenerate, or the area may die. While the nervous system consists of the brain, peripheral nerves, and spinal cord, the circulatory system consists of an intense network of blood vessels along with the heart. Hence, both of these make up the two most important systems in the human body.One of the major queries is about which three-body systems work together. Multiple body systems work together to run your body and to give life to the overall human body. However, the most important has to be the respiratory system, circulatory system, and digestive system. The respiratory system works to take in oxygen from the air while exhaling the carbon dioxide. And, the circulatory system works to deliver the oxygenated blood to different parts of your body while bringing back the deoxygenated blood to be purified by the heart. Along with that, the digestive system lets you derive energy from the food you eat. Having said that, you do need to remember that other human body systems like the cardiovascular, urinary, and lymphatic systems help to maintain the balance of water in your body. While the cardiovascular, integumentary respiratory, and muscular systems work to maintain your body temperature.How Does The Immune System Protect Us From DiseasesOne of the reasons we can fight off viruses and bacteria is because of the immune system. So, let’s learn a bit about it.First, you need to know about the integumentary system that consists of the skin, nails, and hair. Along with being our body’s largest organ, the skin helps to keep your internal organs safe from a lot of pathogens and harmful things that might have otherwise entered the body. That’s why whenever there is a cut on your skin, the immune system of your body does its best to heal it. It can work for a simple thing like a pimple, which is formed due to blocked hair follicles. Now, coming to the immune system, it consists of organs like the lymphatic glands, thymus, lymphatic vessel, and pancreas. One of the key components of our immune system is the white blood cells that are great at defeating all kinds of intruders. Your immune system mainly works by detecting any antigens present in bacteria, viruses, fungi, or any foreign bodies entering your blood supply. The white blood cells are mainly present in the lymphatic system that work to drain excess bodily fluids. And, these small bean-like organs also work to trap the germs and put an end to them. That’s exactly the reason why when you have a cold or a fever, the lymph nodes on your armpits or neck may swell. The best part is that the immune system of our body learns to adapt to the circumstances; hence, the immunity of humans may vary based on their location.You should know that even the saliva that your mouth produces on a daily basis helps to kill many bacterias and germs. And, the taste buds are there to detect any food that’s suspicious and let your nervous system know about the threat, leading to you spitting it out.Which body system is the pancreas a part of?Little did you know that the pancreas does more things than just producing insulin, and it’s actually part of both the digestive system as well as the endocrine system in humans.As you may know, the pancreas is one of the only human organs that is part of two major body systems. Along with producing digesting juices to aid the small intestine, the pancreas also releases the much-needed hormone, the insulin that regulates sugar in our system. When there is improper production of insulin, you may suffer from diabetes. Most of the pancreas is built of exocrine tissue, and every day the pancreas of an adult human produces around 800 ml (0.8 l) of enzymes.Now, apart from the pancreas, the stomach plays the biggest role in the digestive system. Apart from being used as a temporary storage space for the food, you have eaten, this organ also helps to break down the food by producing gastric juices. The stomach plays a key part in breaking down the food into components that can be easily digested in the small intestine. The digestive system of humans includes the organs of the mouth, esophagus, stomach, small intestine, large intestine, rectum, anus, pancreas, spleen, and gall bladder.Which part of the body is the control center for the nervous system?When it comes to finding the control center of your central nervous system, it has to be the human brain.The human brain is one of the most powerful organs present among all animals. It has helped us to evolve into a being with consciousness. Even though underrated, the brain controls everything that goes in our body. We still have a lot of things to learn about the brain.Our brain is attached to the spinal cord, and together these organs help to transmit information around our body so that every organ can perform the set duties. The human heart beats due to the brain sending its inputs to purify the blood to be used by the rest of the body.However, one of the most important functions of the brain is to store your memories and help to navigate cognitive or motor functions. One of the weirdest facts about the human body is that the brain uses up to 20% of the oxygen taken by your body even though it has only 2% of the whole body mass.Did you know?Apart from the major facts about the human body, there are always some facts that aren’t talked about, so we will shed light on them.As we have already told you, our hair is an important part of the integumentary system, and its main job is to protect your scalp as well as the outer layer of your skin from getting damaged. The average rate of growth of human hair is around 6 in (15 cm) per year. It is the second-fastest growth rate in our body except for bone marrow.Even though our organs may look quite proportional, in most cases, there is a slight difference seen between the organs. For instance, our left lung tends to be around 10% smaller than the right lung. Similarly, our right kidney is often bigger than the left one. Interestingly, there is a condition known as renal agenesis, where a person can be born with a single kidney. Asymmetry is also found in other organs like eyes or even in ears. An interesting fact about the human eye is that we are the only animals to shed tears due to emotions.Coming to the skeletal system, there are a lot many interesting to know about our precious bones. Your femur or thigh bone is the longest bone of your body, while the smallest bone belongs to the ear. The stirrup bone present in the middle ear is considered to be the smallest bone.The human body has around 60,000-100,000 m (96,560-1,60,934 km) of blood vessels. It’s said when laid out, blood vessels can travel three times around the world. Your blood vessels can also be driven by the weather and can contract or expand based on the temperature. The blood vessels in the human heart pump blood to all parts of the body. And, it’s said that for an average human, the heart beats around three million times till their death.It’s believed that an average human sheds around 8 lb (3.6 kg) worth of dead skin cells every year. And, the dead skin cells also make up most of the dirt you see around the house. In a 24 hour period, you shed up to five billion skin cells from your body.Even though we aren’t exactly sure what gives life to a human body, the cells are thought to be the basic components that form our body, and together it forms everything from bones, tissues, skin, to even vital organs.Here at Kidadl, we have carefully created lots of interesting family-friendly facts for everyone to enjoy!
