HUMAN RESPIRATORY SYSTEM
Do you know
what helps your body get system. Can you tell me the most
important organs in the respiratory system? yes,
your nose, mouth, trache, lungs, and diaphragm. [ GENERAL STATEMENT ]
The respiratory system,
in anatomy and physiology, are organs that deliver oxygen to the circulatory system for transport to all the body cells. The respiratory and circulatory
systems work together to deliver oxygen to cells and remove carbon dioxide in a two phase process called respiration. [
EXPLANATION 1 ]
The first phase
of respiration begins with breathing in or inhalation. This inhalation brings air form outside
the body into the lungs. Oxygen in the air moves from the
lungs through blood vessels to the heart, which pumps the oxygen rich blood to all parts
of the body. Oxygen then moves from the blood stream into cells, which completes the first phase of respiration. In the cell, oxygen is used in a separate energy producing process called cellular respiration, which produces carbon dioxide as a
by product. [ EXPLANATION 2 ]
The second phase
of respiration begins with movement of carbon dioxide from the cells to the bloodstream. The bloodstream carries carbon dioxide to the heart, which pumps the carbon dioxide laden blood to the lungs. [ EXPLANATION 3 ]
In the lungs, breathing
out or exhalation removes carbon dioxide from the body, thus completing
the respiration cycle. Do you understand so far?
(the bell rings) Well,sorry. I guess time is up for today. Bye [
