Essay Question: Explain how the circulatory system and respiratory system work
together?

Cardiovascular and Respiratory Systems
The circulatory and respiratory systems work together to deliver oxygen and
other important nutrients to every cell in our bodies. All of our body cells
require oxygen to conduct cellular respiration. In this process, oxygen burns
the nutrients from the foods we eat, providing energy for the cells.The
respiratory
system is responsible for bringing oxygen into the body and removing
waste gases, and it is the job of the circulatory system to deliver it to the
body’s trillions of cells.When air is inhaled through the nose and mouth, the
air travels past the larynx, where speech sounds are made, down the trachea,
or windpipe, and into two bronchial tubes. Each bronchial tube goes into one
of our two lungs and further subdivides into smaller branches, called
bronchioles.
Finally, the air reaches tiny balloon-like sacks, called alveoli, of which
there are more than 300 million in each lung. Each of the alveoli is
surrounded
by tiny blood vessels, called capillaries, carrying red blood cells that pick up
oxygen in the alveoli and release carbon dioxide, which is then exhaled out
of
the body.The maximum amount of air the lungs can hold is called vital lung
capacity. Factors like size, gender, health and age contribute to lung
capacity.
