The human body comprises a billion to trillion cells; several other tissues, organs, and organ systems carry out different biological functions required for growth and development.
Many vital organs play a crucial role in keeping us alive, active, and healthy. These essential organs include:
The skeletal system
The nervous system
The muscular system
The circulatory system
The respiratory system
The reproductive system
Humans are the most fascinating and complicated living organisms on Earth. Compared to other living species, humans are the only creatures with chins.
There are many other interesting facts about the human body.
Let us have a look at some amazing facts about the human body.
