The human body is made up of cell types, organs, tissues and other biological systems that perform a variety of different functions necessary to maintain good health.
The scientific study of the structure and function of the body is called human anatomy and physiology. Apart from these structures and functions, there are many amazing facts about our bodies that not all of us are aware of. Below are some interesting facts about the human body.

- Like our fingerprints, everyone’s tongue mark is different. The human tongue can produce enough saliva to fill two swimming pools and is considered the most powerful muscle in our body.
- Both the circulatory and respiratory systems are involved in the transport of blood and oxygen throughout the body. The human heart beats 100,000 times a day and 30 million times a year.
- Human ears can hear sounds at frequencies between 2000 and 60,000 Hz and can distinguish between hundreds of thousands of different sounds.
