Ответьте пожалуйста на вопросы по этому тексту: There are
several main systems of the body: the skeletal, the muscular, the nervous, the
digestive, the respiratory, the urinary, the endocrine and the reproductive
systems.
The skeletal system consists of the
bones of the body and ligaments and cartilages, which join them. The chief
function of the skeletal system is structural.
The muscular system consists of the
skeletal muscles and their associated structures. The main function of this
system is to move us about.
The nervous system consists of the
brain and spinal cord, nerves, ganglia and receptors. It is a complex
information system with all the necessary means for receiving, processing and
communicating information.
The circulatory system consists of the
heart and blood vessels and the blood, which is pumped through the blood
vessels by the heart. Its function is mainly that of transportation system: the
nutrients, oxygen, special substances which are required by cells are carried
by the blood stream; and the cellular wastes and sometimes other materials
produced by the cells are carried away by the blood stream.

The digestive system consists of the
alimentary canal and a number of associated glands.
The respiratory system consists of the
lungs, the air passages leading to them and associated structures. Its main
function is to convey oxygen to the lungs, where it can enter the blood stream
and to remove carbon dioxide, which escapes from the blood into the lung
spaces.
The urinary system consists of the
kidneys which produce urine by removing nitrogenous and other wastes from the
blood: the two ureters, which convey the urine away from the kidneys; the
urinary bladder, where the urine is stored until it is discharged; and the
urethra through which the urine is discharged.
The endocrine system consists of a number of glands throughout the
body, which produce regulatory substances called hormones. The endocrine system
serves to regulate a large number of activities
