Exercise 7. Read and translate the text:

The Anatomy and Physiology of the Respiratory System

The cells of the human body require a constant stream of oxygen to stay alive. The respiratory system provides oxygen to the body’s cells by removing carbon dioxide. It is the respiratory system that is responsible for the respiration, the process by which our organism exchanges gases with its environment. The act of breathing with the lungs is called ventilation and includes inhalation (breathing in) and exhalation (breathing out).

There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration.

The airway includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles.

The nose and nasal cavity form the main external opening for the respiratory system through which air moves. The nasal cavity is a hollow space within the nose and skull that is lined with сilia, which are very fine hairs, which warm, moisturize and filter air. These hairs are coated with mucus that captures any germs and pollutants that are in the air we breathe before it enters the lungs. This foreign matter is then expelled from the body through swallowing, coughing or sneezing.

The mouth or the oral cavity is the secondary external opening for the respiratory tract. It can be used to supplement or replace the nasal cavity’s functions when needed.

The pharynx, also known as the throat, is a muscular funnel. It extends from the nasal cavity to the larynx and esophagus.

The larynx, also known as the voice box, is a short section between the pharynx and trachea.

The trachea is a tube which extends from the base of the larynx to the lungs, where it divides into two bronchi.

The bronchi are two tubes which begin at the trachea. The left bronchus is longer than the right one as it passes around the heart to reach the left lung. Each bronchus leads into a lung. In the lungs, the bronchi divide into bronchioles. The bronchioles end in fine alveolar ducts leading to the alveoli.

The alveoli, or air sacs, are the ends of the air passages. Each alveolus is closely surrounded by blood capillaries.

The lungs are paired, spongy organs located in the chest. They are not identical in shape and size. The left lung is smaller than the right one because it shares space in the chest with the heart. They are divided into lobes - the right lung has three lobes and the left lung has two lobes. The vital capacity of the lungs in the adult is about 3-4 liters.

When one breathes normally not all the alveoli and capillaries of the lungs are opened. When respiration becomes deep, the number of the opened alveoli and capillaries increases. The flow of blood into the lungs increases when one breathes in and it decreases when one breathes out.
