Грамматический материал
В английском языке глаголы могут иметь два залога: действительный залог (the Active Voice) и страдательный залог (the Passive Voice). Глагол в действительном залоге обозначает действие, которое производится подлежащим:
I examined the patient. Я осмотрел больного.
Глагол в страдательном залоге обозначает действие, которое производится над подлежащим:
I was examined. Я был осмотрен/Меня осмотрели.
В английском языке глаголы делятся на объектные и необъектные. Необъектные глаголы выражают действия, которые не могут быть направлены на какой-то объект. Эти глаголы не имеют при себе дополнения и не могут употребляться в страдательном залоге.
Примером необъектных глаголов являются следующие глаголы: to go — идти, to live — жить, to come — приходить, to work — работать.
Объектные глаголы выражают действия, которые могут быть направлены на какой-нибудь объект. Они могут иметь при себе прямое, косвенное и предложное дополнение.
Примером объектных глаголов являются следующие глаголы:
to examine осматривать Я осматривал (кого? что?)
больного.
to give давать Он дает (кого? что?) урок.
to see видеть Мы видели (кого? что?) вас.
В страдательном залоге могут употребляться только объектные глаголы.
Времена страдательного залога группы Simple образуются при помощи вспомогательного глагола to be в Present, Past или Future Simple и причастия II смыслового глагола.
В вопросительной форме вспомогательный глагол ставится перед подлежащим, причем в Future Simple на 1-ое место ставится вспомогательный глагол shall или will.
Отрицательная форма образуется при помощи отрицательной частицы not, которая ставится после вспомогательного глагола, при этом в Future Simple эта частица ставится после 1-го вспомогательного глагола shall или will.

The Human Respiratory System
This system includes the lungs, pathways connecting them to the outside environment, and structures in the chest involved with moving air in and out of the lungs.
Air enters the body through the nose, is warmed, filtered, and passed through the nasal cavity. Air passes the pharynx (which has the epiglottis that prevents food from entering the trachea).The upper part of the trachea contains the larynx. The vocal cords are two bands of tissue that extend across the opening of the larynx. After passing the larynx, the air moves into the bronchi that carry air in and out of the lungs.
The lungs and alveoli and their relationship to the diaphragm and capillaries.
Bronchi are reinforced to prevent their collapse and are lined with ciliated epithelium and mucus-producing cells. Bronchi branch into smaller and smaller tubes known as bronchioles. Bronchioles terminate in grape-like sac clusters known as alveoli. Alveoli are surrounded by a network of thin-walled capillaries. Only about 0.2 µm separate the alveoli from the capillaries due to the extremely thin walls of both structures.
The lungs are large, lobed, paired organs in the chest (also known as the thoracic cavity). Thin sheets of epithelium (pleura) separate the inside of the chest cavity from the outer surface of the lungs. The bottom of the thoracic cavity is formed by the diaphragm.
Gas Exchange in the Respiratory System
The condition of the airways and the pressure difference between the lungs and atmosphere are important factors in the flow of air in and out of lungs. Many diseases affect the condition of the airways.
The Alveoli and Gas Exchange
Diffusion is the movement of materials from a higher to a lower concentration. The differences between oxygen and carbon dioxide concentrations are measured by partial pressures. The greater the difference in partial pressure, the greater the rate of diffusion. Respiratory pigments increase the oxygen-carrying capacity of the blood. Humans have the red-colored pigment hemoglobin as their respiratory pigment. Hemoglobin increases the oxygen-carrying capacity of the blood between 65 and 70 times. Each red blood cell has about 250 million hemoglobin molecules, and each milliliter of blood contains 1.25 X 1015 hemoglobin molecules. Oxygen concentration in cells is low (when leaving the lungs blood is 97% saturated with oxygen), so oxygen diffuses from the blood to the cells when it reaches the capillaries. Gas exchange across capillary and alveolus walls.
