Transcript The circulatory system by Ryanx

Circulatory System - the system of blood, vessels, and heart concerned with circulation of body fluids.
Plasma - the watery part of blood cell that carries nutrients wastes, and blood cells.
Red Blood Cell - the kind of blood cell that carries oxygen to other body cells.
White Blood Cells - the kind of blood cell that fights germs.
Platelet - a tiny part of a cell that helps stop bleeding.
Artery - the kind of blood vessel that carries blood away from the heart.
Capillary - a tiny blood vessel with thin walls through which oxygen, nutrients, and wastes past
Vein- the kind of blood vessel that carries blood back to the heart.
veins.
Ventricle - one of two spaces in the bottom part of the heart that pump blood out of the heart.
Atrium - one of two spaces in the top part of the heart that receive blood from

The circulatory system is made of a network
of flexible tubes that carry blood to all parts
of the body. The major parts of the
circulatory system includes the heart, lungs,
arteries, and veins. Have you ever heard
the sound of a heart beating? Click here to
hear what your heart sounds like to your
doctor. With each beat, the heart pumps
blood that delivers life-sustaining oxygen
and nutrients to your body's 300 trillion cells.

facts about the heart and circulatory
system.

One of the most interesting facts of circulatory system is
how it functions. The heart pumps blood, which is sent to
the four chambers of the heart. The heart has two
ventricles and two atria. The left ventricle pumps
oxygenated blood to the other organs of the body; on the
other hand, the right ventricle pumps the blood to the
lungs. The heart has four valves which control the flow of
the blood. The right atrium contains blood that is low in
oxygen. When the valve opens, this blood is pumped into
the right ventricle, similarly another valve opens to pour
the blood into the pulmonary artery which carries the
blood to the lungs for oxygen. The left atrium brings
oxygenated blood into the left ventricle via another valve
and into the aorta, which then sends the blood to the
other body parts. Take a look at some other circulatory
system facts by reading how does the circulatory system
work.

The left side of the heart contains oxygenated blood whereas the right side has deoxygenated blood.
One drop of blood has about 5 million red blood cells and 12 thousand white blood
cells.
The heartbeats about 30 million times in 365 days.
10 million blood cells die in the human body every second, the same quantity is
produced at the same time.
Blood circulates the entire body in 20 seconds.
An average heart pumps about 450 gallons of blood everyday.
One of the surprising circulatory system facts is that the heartbeat is the sound of the
valves opening and closing.
An average adult's body has about 5 liters of blood in it and a baby's body has about 1
liter of blood in it.
A human heart is a muscle which is the size of a clenched fist.
Blood cells die in every 4 months.
The plasma in the blood is made in the liver.
One of the amazing facts of circulatory system is that the heart continues to beat even
when it is taken out of the body!
