1. Organ systems and their major functions in the human body
Skeletal system 
Nervous system  
Endocrine system
Muscular system 
Lymphatic and immune
Circulatory system
Organs of special senses
Visceral system

2. The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulation.
There are three distinct types of muscles: skeletal muscles, cardiac or heart muscles, and smooth muscles. Muscles provide strength, balance, posture, movement and heat for the body to keep warm.
Functions of the Circulatory system :respiration, nutrition, waste removal , cellular communication, thermoregulation

3. Nervous system :
At the most basic level, the function of the nervous system is to send signals from one cell to others, or from one part of the body to others. There are multiple ways that a cell can send signals to other cells. 
At a more integrative level, the primary function of the nervous system is to control the body.

4. The lymphatic system plays a major role in body's immune system, as the primary site for cell relating to adaptive immune system including T-cells and B-cells. 

5. Humanoid robot
A humanoid robot is a robot with its body shape built to resemble the human body
Humanoid robots are now used as a research tool in several scientific areas.
Researchers need to understand the human body structure and behavior (biomechanics) to build and study humanoid robots. On the other side, the attempt to the simulation of the human body leads to a better understanding of it.
