Because he was a monk, not a scientist, and his work was not widely published.
The head should be positioned in the upper of the body.
The weight of the center body should be over the pelvis.
The legs and knees should be stable enough to support that body's weight
Explanation:
For humans to keep a balance while walking, their body must be properly positioned in the right manner.
- The head must be fixed and positioned straight on the upper body. It should not at any point be unbalanced by being projected too forward or backward or to the side.
- The weight of the center body should be over the pelvis. The alignment gives the proper positioning of the center of gravity of the human body.
- The pelvis should carry and spread the weight of the body to the body parts that attaches to it.
- The legs and knees should be straight and stable to support the weight of the body.
- If they are not strong enough the body will wobble and not be balanced.

A fuel cell works like a battery. It consists of two electrodes where the reactions would occur and an electrolyte solution which allows for caharged particles to flow. In a fuel cell that uses hydrogen and oxygen as reactants. The hydrogen would enter the cell at the anode where oxidation would happen. So that the species that is formed in the anode side would be hydronium ions and electrons. The oxygen, on the other hand, would enter the cathode electrode where reduction occurs. The species that are produced in this side of the cell are water molecules. Together, the net reaction is called a redox reaction.
The respiratory and circulatory system both work together <span>to get oxygen to a cell in your knee: the respiratory system brings the oxygen into the body and for the circulatory system, the heart pumps red blood cells to deliver oxygen to locations throughout your body. Hope this helps! :)</span>
