The Right Lung Is 10 Percent Bigger Than the Left One
Spongy tissue that is soft and elastic make up the human lungs. It is pinkish in color and has a trachea through which air enters the lungs. The trachea has two branches referred to as bronchi. The bronchi further divides into bronchioles. They attach themselves to the alveoli, are small sacs where carbon dioxide and oxygen exchange. A web of blood vessels wraps around each sac in order to allow the exchange of gasses via the alveoli. One of the most interesting human body facts is that if you open it up, the alveoli has a surface area that can cover a tennis ball court.
The Human Nose Has the Capability of Detecting a Trillion Smells
According to estimates, the human nose can detect, differentiate, and distinguish over a trillion scents. This is contrary to the old human body facts study which had estimated that the human sense of smell could only detect about 10,000 odors. This is contrary to the existing myth which suggests that human beings are poor at detecting smells.
According to a human body facts study by Rockefeller University neurobiologists Leslie Vosshall, human beings can detect more smells than previously thought. Humans can detect smell by inhaling the air that contains the odor molecules. The odor binds to the receptor inside one’s nose and relays the message to the brain which in turn processes it and unveil the information.
A Person’s Belly Button has about 67 Different Species of Bacteria
According to human body facts studies, the belly button has more than 2368 different species of bacteria, most of which lie in the in the archaea. On average, each person harbors about 67 different species of bacteria but people who bath don’t regularly yield more species. Scientists have always wondered why the species differ and vary from one person to another. However, they all agree that there are many factors that contribute to the differences in the species of bacteria found in human beings.
Babies Start Shedding a Tear After They Are One Month Old
Babies enter the world by crying. However, human body facts studies show that they only cry and do not shed tears. The reason is that their tear glands are underdeveloped and only produce enough fluids to keep the eyes moist. So you will not see tears running until the child is between 1-8 months old. If they shed tears before one month, they have blocked tear ducts which will unblock within the first year. Help the tear ducts to unclog by massaging them or seeking medical help.

The human heart beats between a range of 70 and 110 beats per minute depending on the age, size of the person, and the situation people find themselves in. When exercising, the heartbeat increases to help supply more oxygen to various parts of the body, including other muscles in the body. In some strenuous cases, the heartbeat may go up to 200 times per minute. However, all said and done, scientists estimate that on average, the heartbeat will be more than three billion times for an average lifespan.
Human Teeth Are As Strong As the Teeth of a Shark
Even though the size and the number of teeth in the tiger shark are not the same, they are just as strong. Scientists made this discovery while investigating amazing human facts that compared the teeth of human beings to those of sharks. They discovered that even though the teeth of the shark are coated with a tough enamel, the teeth are not stronger than those of human beings.
Human Being Lose 4 kg of Skin Cells per Year
The skin is one of the most important organs of the body. In fact, one of the interesting human body facts about the skin is that it changes over time in its endeavor to perform its function.
