I remember my first Anatomy lecture at the medical school of the University of Witwatersrand with Prof. Tobias
He introduced a pair of black belt judoka and ballerinas to the students, before taking the Hippocratic Oath and  dissecting cadavers. Professor Tobias wanted us to understand that the Hippocratic Oath was a promise to respect human dignity. We were going to dissect the body into all its parts over the year.
The judoka and ballet dancers were to remind us how these parts working together brought perfection: parts making the whole, and the whole bigger than the parts. This philosophy has remained with me all my life.
The organs themselves are formed by the cells which are the basic building blocks of the tissues and organs
