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.

Ответы
Ответ:
1. Anatomy refers to the internal and external structures of the body and their physical relationships, whereas physiology refers to the study of the functions of those structures.
2. The human body is approximately 99% comprised of just six elements: Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus. Another five elements make up about 0.85% of the remaining mass: sulfur, potassium, sodium, chlorine, and magnesium.
3. a constant supply of energy to generate and maintain the biological order that keeps them alive.
4. Energy comes from the three main nutrients carbohydrates, protein, and fats, which come from food
5. Digestion is the process of mechanically and enzymatically breaking down food into substances for absorption into the bloodstream.
6. The respiratory system includes the nose, mouth, throat, voice box, windpipe, lungs, and diaphragm.
7. Kidneys filter out metabolic waste, and excess fluid and eliminate it in the form of urine.
8. In the past, the brain has been said to be like a water clock and a telephone switchboard. These days, the favorite invention that the brain is compared to is the computer.
9. Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by the division of the parent cell into two daughter cells, so yes, it is.
10. DNA is responsible for building and maintaining your human structure. Genes are segments of your DNA, which give you physical characteristics that make you unique.
11. The arteries branch off into smaller and smaller tubes. These bring oxygen and other nutrients to the cells of the body's tissues and organs.
