The motor neuron is the longest cell in the human body, the feminine egg is the largest cell, and the male sperm cell is the smallest. The thigh bone is the longest, and the smallest bone is the stapes or stirrup in the middle ear. The jawbone is the hardest bone. The skin is our largest organ, and the pineal gland is our smallest. The human tongue is the strongest muscle, and the external eye muscles are the fastest, as they are constantly moving, blinking, and adjusting the position of the eye.
Facts No – 5
A typical person breathes 20,000 times per day. When compared to men, children, and women breath more quickly. The faster our metabolism, the deeper we breathe.
Facts No – 6
Our appetite is influenced by how we breathe. Slow breathing can help us live longer lives. To avoid infections, tonsillitis, sore throats, and other problems, we should always breathe through our nose.

Facts No – 7
Yawning allows us to breathe in more oxygen into our lungs. When our brain detects a lack of oxygen, it sends a message to our sensory system, which causes us to yawn.
Facts No – 8
Blood travels approximately 19,312 kilometers in a day, and our hearts pump approximately 1.5 million barrels of blood in our lifetime, enough to fill 200 train fuel tanks.
Facts No – 9
Every human being has a distinct tongue print, similar to our fingerprints. The human tongue can produce enough saliva to fill two swimming pools and is the strongest muscle in our body.
Facts No – 10
Both the circulatory and respiratory systems are involved in transporting blood and oxygen gas throughout the body. The average human heart beats 100,000 times per day, or 30 million times per year.
Facts No – 11
Human ears can distinguish between hundreds of thousands of different sounds at frequencies ranging from 2,000 to 60,000 hertz.
Facts No – 12
The cornea, the transparent front part of the eye, is the only part of the eye that does not have a blood supply and must obtain oxygen directly from the air.
Facts No – 13
A human circulatory system is made up of over 100,000 miles of blood vessels. The aorta is the largest blood vessel. An adult human body contains 100,000 miles of blood vessels on average.
Facts No – 14
Fingernails grow faster than toenails, and the middle finger’s nail grows faster than the other fingernails. The middle fingernail grows more quickly than the other fingers.

Facts No – 15
We are unable to breathe and swallow at the same time. However, newborn babies can breathe and swallow simultaneously for up to 7 to 8 months.
Facts No – 16
Human eyes and ears never stop growing because they are primarily made up of cartilage cells, which divide with age. Human teeth are as strong as shark teeth, and the teeth contain approximately 99% of the total calcium content in the body.
Facts No – 17
The size of our noses and ears grows with age, but the size of our eyes remains constant from birth. Our nose is the size of our thumb finger, and our ears grow a quarter millimeter per year.
Facts No – 18
The lungs are an essential component of the human respiratory system and the only organ in the human body that can float in water. According to studies, the human nose can detect and distinguish between one trillion different types of odors.
Facts No – 19
The total number of bacteria in our mouths is the same as the total number of people on the planet. These bacteria do not harm us and, as a result, protect us from disease-causing organisms.
Facts No – 20
A single hair follicle has a lifespan of about 3 to 7 years. The dark colour of our hair aids in the identification of the density and total number of hair follicles in our head.

Frequently Asked Questions on Facts About the Human Body
What is the most amazing thing about the human body?
- Without oxygen, the brain can survive for several minutes.
- The size of both lungs is not the same.
- The largest organ is the skin.
- Adults have 206 bones, whereas babies have 300.
- The term “Products” refers to the products that are available.
What is the largest organ?
The largest organ in the human body is the skin. It is a complex organ that covers the entire body and is responsible for protecting us from the external environment. The skin has many important functions, including regulating body temperature, detecting sensation, producing vitamin D, and serving as a barrier to prevent infection and dehydration.
The skin is composed of three main layers: the epidermis, the dermis, and the hypodermis. The epidermis is the outermost layer and is responsible for protecting the body from the environment. The dermis is the middle layer and contains the blood vessels, nerves, and hair follicles. The hypodermis is the innermost layer and contains fat and connective tissue.
The skin is also the largest sensory organ in the body, containing millions of nerve endings that allow us to feel touch, pressure, pain, and temperature. Its importance to our overall health and wellbeing cannot be overstated.
What is the heaviest body part?
The heaviest body part in the human body is the skin, which can weigh up to 10 pounds or more, depending on a person’s size. However, if we consider internal organs, the heaviest one is typically the liver, which weighs around 3 pounds in adults. Other relatively heavy organs include the brain (around 3 pounds), the heart (around 0.6-1 pound), and the lungs (around 1-2 pounds each). It’s important to note that these weights can vary widely depending on a person’s size, age, and overall health.
What organs can you live without?
The human body has several organs that are considered vital for survival, but there are a few organs that can be removed or no longer function properly without necessarily causing death or significant long-term harm. Here are some examples:
- Spleen: The spleen is an organ located in the abdomen that helps filter the blood and fight infections. However, it is possible to live without a spleen, as other organs can take over its functions.
- Gallbladder: The gallbladder is a small organ located near the liver that helps with digestion by storing and releasing bile. It is possible to live without a gallbladder, but some people may experience digestive issues.
- Appendix: The appendix is a small pouch located in the lower right abdomen. While its function is not entirely clear, it is not essential for survival and can be safely removed in cases of appendicitis.
- Kidney: While it is ideal to have two healthy kidneys, it is possible to live with just one functioning kidney.
- Reproductive organs: While reproductive organs are important for reproduction, they are not essential for survival.
It’s important to note that while it’s possible to live without these organs, their removal or dysfunction can have long-term consequences and may require medical treatment.
What is the fattiest organ in your body?
The liver is the fattiest organ in the human body. It normally contains some fat, but if the amount of fat exceeds 5-10% of the liver’s weight, it is called “fatty liver.” Fatty liver disease can occur due to various reasons, such as obesity, diabetes, high cholesterol, and alcohol abuse. Fatty liver disease can lead to liver inflammation, scarring, and damage, and in some cases, it can progress to liver failure. Therefore, it’s important to maintain a healthy lifestyle to prevent fatty liver disease and other liver-related conditions.
Which organ can store blood?
The organ that can store blood is the spleen. The spleen is a fist-sized organ located in the upper left part of the abdomen, near the stomach. It is responsible for filtering the blood, removing old or damaged red blood cells, and producing new ones. The spleen can also store a significant amount of blood, which it can release into the circulatory system in case of an emergency, such as blood loss or shock. This process is known as splenic contraction or splenic reserve, and it can help maintain blood pressure and provide the body with the necessary oxygen and nutrients until additional blood can be transfused.
