Circulatory System
(cardiovascular)
Here’s my story,
Circulatory,
It's what they call my system,
I got veins and arteries,
For blood,
And you can’t miss ‘em…
Surely, I am circulatory,
Blood's pumped,
Round and round...
Use my heart,
And blood vessels,
Surely will astound…
Veins bring blood,
To my heart,
To lungs,
Is where it's pumped...
Oxygen comes from lungs,
My heart goes thump-thump-thump...
Blood from lungs,
Returns to heart,
And then to artery,
Which carries blood,
To every organ,
In every part-a-me…
Surely, I am circulatory,
I pump blood round and round,
Use my heart,
And blood vessels,
I surely I will astound!
Circulatory system: The circulatory or cardiovascular system is a closed organ system made up of the heart, veins, and arteries. Its main function is to move blood throughout the body. Veins carry blood back to the heart where it is reoxygenated by the lungs before it returns to the body through arteries. Along with delivering oxygen and removing carbon dioxide, the circulatory system supplies nutrients from the digestive system, and lymph (an important part of the body's immune system.)
