Let's speak about human anatomy and physiology,which are the study,respectively,of the normal structure and functioning of the body.Just as houses are built of individual bricks,so is the body made up of millions of microscopic individual urits called cells.Each cell has a job to do and must be supplied with fuel and oxygen before it can do it.In this respect the body is not different from any other working engine or machine.All engines,machines and body cells are alike in requiring oxygen to burn their fuel and thereby produce the energy needed to perform their functions.
The fuel needed by the body comes from our food,while oxygen is present in the air we brea the.Fuel and oxygen are conveyed in the blood to all parts of the body by the heart and circulation.
The food we eat is turned into usable fuel by a process known as digestion.The digestive system contains the stomach and intestines.
Oxygen is obtained from the air we breathe.The process by which it enters the blood to reach the body cells is called respiration.The respiratory system consists of the air passeges and lungs.
Overall control and coordination of body functions is effected by the nervous system, which consist of the brain and nerves.The brain may be likened to a computerized telephone exchange with the nerves serving as telephone lines.
There are many different types of cell in the body,depending on their particular function,but they all contain a central nucleus and are bounded by a cell wall.The nucleus is responsible for growth by cell division,and contains chromosomes and genes which transmit the hereditary factors,which make every person a unique individual.The cell wall is sufficiently thin to allow oxygen and nutrients from the blood to enter the cell and waste products to leave.

Ответ:
1. What are the functions of the skeletal and muscular system? they protect the body's organs, support the weight of the body, and give the body shape.
2. What is carried by the blood stream? oxygen and nutrients to all the parts of the body
3. What is the chief function of the blood? transporting oxygen and nutrients to the lungs and tissues. forming blood clots to prevent excess blood loss. carrying cells and antibodies that fight infection.
4. What does the nervous system consist of? the brain, spinal cord, and a complex network of nerves.
5. What is the main function of the respiratory system? transport oxygen and remove extra carbon dioxide.
6. What does the urinary system consist of? kidneys, renal pelvis, ureters, bladder and urethra.
7. How do the kidneys produce urine? kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine.
8. How is the urine discharged from the body? When a person urinates, the pee exits the bladder and goes out of the body through the urethra
