Question

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 Вопросы: 1) What are the functions of the skeletal and muscular systems? 2) What is carried by the blood stream 3) What is the chief function of the blood 4) What does the nervous system consist of 5) What is the main finctions if the respiratory system 6) What does the urinary system consist of 7) How do the kidneys produce urine 8) How is the urine discharged from the body

Answer 1

1. The chief function of the skeletal system is structural. The main function of the muscular system system is to move us about.
2. The nutrients, oxygen, special substances which are required by cells, the cellular wastes and sometimes other materials produced by the cells are carried away by the blood stream.
3. The chief function of the blood is transporting.
4. The nervous system consists of the brain and spinal cord, nerves, ganglia and receptors.
5. The main function of the respiratory system 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.
6. The urinary system consists of the kidneys, the two ureters, the urinary bladder and the urethra.
7. The kidneys produce urine by removing nitrogenous and other wastes from the blood.
8. The urine is discharged through the urethra.

Answer 2

1. The function of the skeletal system is primarily structural, providing support, protection, and shape to the body. The muscular system's main function is to facilitate movement by contracting and relaxing the skeletal muscles.

2. The blood stream carries nutrients, oxygen, special substances required by cells, as well as cellular wastes and other materials produced by the cells.

3. The chief function of the blood is to act as a transportation system. It carries nutrients, oxygen, hormones, and other essential substances to the cells of the body, while also removing cellular wastes and carbon dioxide.

4. The nervous system consists of the brain, spinal cord, nerves, ganglia, and receptors. It is responsible for receiving, processing, and communicating information throughout the body. It serves as a complex information system, facilitating sensory perception, motor coordination, and overall body control.

5. The main function of the respiratory system is to facilitate the exchange of gases. It conveys oxygen to the lungs, where it enters the bloodstream, and removes carbon dioxide, which escapes from the blood into the lung spaces.

6. The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys produce urine by removing nitrogenous and other waste products from the blood. The urine is then conveyed from the kidneys to the bladder through the ureters, stored in the bladder until it is discharged, and finally eliminated from the body through the urethra.

7. The kidneys produce urine through a process called filtration. They filter waste products, excess water, and other substances from the blood. The filtered material, known as urine, is collected in the renal tubules of the kidneys.

8. Urine is discharged from the body through the urethra. When the bladder contracts, the urine is expelled through the urethra and eliminated from the body during urination.
