Transcript Circulatory System

By Tre’ and Joe
The heart is the main organ in the
circulatory system. The heart has four
places that help with the other organs.
The four places are the right atrium,
right ventricle, left atrium, and left
ventricle. When you inhale air from the
lungs the red blood cells go's through the
left side of the heart where the blood
cells get the O2(oxygen) and while in the
left side they go through the left atrium
and ventricle to go to the arteries to help
the other parts of the human body. Then
the blood cells go’s back to the heart but
the right side where they go through the
right atrium and ventricle while they
carry CO2(carbon dioxide) to the lungs
and you exhale CO2 and the blood cells
keep on doing this until you die. That is
why it is called the circulatory system.

The heart produces 3
million red blood cells a
minute. The reason
being is because red
blood cells die fast. The
resources that red
bloods cells need are
water, food, gases, and a
waste disposal. People
have about 25 trillion
red blood cells. Also a
drop of blood is 5
million blood cells.

White blood cells fight
disease, kill bacteria, combat
allergic reactions, destroy
old and/or damaged cells,
kill invalid organisms. They
work together to surround
bacteria completely,
digesting bacteria with
digestive enzymes.
