10 sentence about respiratory system
Answers
Explanation:
The respiratory system, also called the gas exchange system, is the body getting rid of carbon dioxide and taking in oxygen. Carbon dioxide, a waste product, goes out of the body. Oxygen, which the body needs, comes in. The lungs are the main organ to do this. In other words , a process in which oxidation of organic compounds occurs in cell and energy is released is called as Respiratory system .
The first step in this process is breathing in air, or inhaling. Inhalation means bringing air rich in oxygen into the body. Exhalation means giving out air rich in carbon dioxide from the body. The second step is gas exchange in the lungs where oxygen is diffused into the blood and the carbon dioxide diffuses out of the blood. The third process is cellular respiration, which produces the chemical energy that the cells in the body need, and carbon dioxide. Finally, the carbon dioxide from cellular respiration is breathed out of body from the lungs.
Answer:
These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function
