Cardiovascular SystemDefinition
The cardiovascular system, also known as the circulatory system, is a
complex network in our body that is responsible for the movement of blood
and nutrients throughout the body.
Overall Function
Its main function is to transport oxygen, nutrients, hormones, and cellular
waste products throughout the body. This transportation is vital for the
body to function and stay healthy.
Main Organs/Parts and their Functions
1. Heart: The heart is the essential pump that keeps the entire circulatory
system functioning. Its primary role is to pump oxygenated blood
throughout various parts of the body, ensuring that every cell gets the
oxygen it needs. It’s the engine room responsible for life-sustaining
circulation.
2. Blood vessels: These intricate structures can be likened to the roads
that transport the blood. They form a complex network throughout the
body, and they include the arteries, which carry blood away from the
heart, veins that return it, and the small, delicate capillaries that connect
them and reach every cell.
3. Blood: Blood is the vital transportation vehicle that carries necessary
substances such as nutrients and oxygen to our body's cells and
removes waste products. It's a flowing river of life, bringing the needed
materials for survival to each cell and taking away the waste products
for disposal.
