In my view the human body is like a jungle simply like a cluster of many living things that are dependent on each other.
To understand it more further let’s take an example of Blood for a common person it is read watery substance in biological language it is a mixture of read and white blood Cells which have there own life span (Grow live for some time and destroy or die after completing there life span), reproductive system( through cell division they reproduce and grow) this system is very similar to many of the living micro organisms who have there lives dependent on other elements of nature and not the human body.
In the similar fashion every human cell has similar behavior and they are separate living units dependent on each other for there existence.
These cells form organs like heart, kidney, pancreas etc.
These organs are living beings in there own dependent on other organs and cells for there existence. This is why the human organs can be replaced and transplanted to other humans, any organ not functioning has a effect on the human body system and other organs as well and when this malfunction reaches to a level when other organs of our body are unable to cope up with the functioning of one organ whole ecology of human body gets disturbed and that causes the death of human body.
