Capillaries are minute blood vessels that join onto the arterioles. They are one cell thick and are exchange points where the nutrients (oxygen and glycogen) cross into the tissue cells (muscles) from the arterioles.
An average human body takes from two to three hours to burn completely and will produce an average of 3 to 9 pounds (1.4 to 4.1 kilograms) of ash.The amount of ash depends usually on the bone structure of the person and not so much their weight [source: Ellenberg ].n average human body takes from two to three hours to burn completely and will produce an average of 3 to 9 pounds (1.4 to 4.1 kilograms) of ash.
