Read the facts about the respiratory system and translate them into Ukrainian.
The lungs contain almost 1.500 miles (2.414 km) of airways and over 300 million alveoli.
Every minute the human breathes in 13 pints (6.15 litres) of air.
We exhale about half a litre of water vapour in a whole day.
Breathing is initiated by the diaphragm which is a stretchable muscle under the lungs. The volume of the chest cavity rises and the air pressure drops when the diaphragm contracts. That is what enables the high pressure air outside to enter the lungs and makes them expand like balloons. When the diaphragm expands, lungs are emptied of air and we exhale it outside.
People with asthma have difficulty in breathing because the airways in their lungs become narrow and constricted, due to which, enough oxygen is not supplied through the lungs.
Plants are our partners in breathing. We breathe in air, use the oxygen in it, and release carbon dioxide. Plants take in carbon dioxide and release oxygen.
People tend to get more colds in winter because we’re indoors more often and in close proximity to other people. When people sneeze, cough and even breathe germs go flying!
When we sneeze, particles fly out of the nose at 100 mph (161 km/h). A sneeze is the body’s way of getting rid of something that is irritating the nose.
Match the respiratory system terms with their definitions.
the section of the alimentary canal that extends from the mouth and nasal cavities to the larynx, where it becomes continuous with the oesophagus
the two main branches of the trachea leading directly to the lungs
a protuberance in vertebrates that contains the nostrils, or nares, which admit and expel air for respiration. It also contains the tiny hairs (cilia) which catch airborne particles and prevent them from reaching the lungs. There is the olfactory mucosa and the sinuses within and behind it
a muscular membranous partition separating the abdominal and thoracic cavities and functioning in respiration (also called a midriff)
a soft, spongy organ in the thoracic cavity composed of alveoli, capillaries, and the bronchial tree
air-filled spaces, communicating with the nasal cavity, within the bones of the skull and face. They are joined to the nasal cavity via small orifices called ostia
a thin serous membrane that envelops each lung and makes a lining for the chest cavity
the part of the upper respiratory tract between the pharynx and trachea. It is composed of cartilage pieces that form a box-like structure, a voice box, which contains the vocal cords. Vibration of the vocal cords produces sound for speech
a tiny, thin-walled, capillary-rich sac in the lung where the exchange of oxygen and carbon dioxide takes place (also called an air sac)
a thin-walled, cartilaginous tube descending from the larynx to the bronchi and carrying air to the lungs (also called a windpipe)
