"The circulatory system, also known as the cardiovascular system, is a complex network of organs and vessels that transport blood throughout the body. At its core is the heart, a muscular organ that pumps blood out to the lungs, organs, and tissues.
The circulatory system is made up of:
- The heart, which pumps blood throughout the body
- Arteries, which carry oxygenated blood away from the heart
- Veins, which carry deoxygenated blood back to the heart
- Capillaries, tiny vessels where oxygen and nutrients are exchanged for waste products
- Blood vessels, which transport blood throughout the body
The circulatory system plays a crucial role in maintaining life, delivering essential nutrients and oxygen to cells and organs, and removing waste products. It's a vital system that keeps us alive and functioning!"
