Can the human body be called a biological system?

Let us first recall the very definition of a biological system. It is a collection of elements that form a single organism. All elements have specific functions and interact with the environment. The human body is a system of cells that form all organs and tissues. A person cannot live without organs and tissues, therefore our body is a system.
