About Our Site:
- Circulatory101 was created to give a basic understanding of what the circulatory system is and how this system differs in animals amongst every phylum. We have provided you with animals in each phylum describing what they are and how their circulatory system works. We hope you enjoy.
What is the Circulatory System?
The Circulatory System is a system in the body that transports oxygen, nutrients, and other substances throughout the body, specifically to organs and other areas of the body that need it, and removes wastes from tissues.
This system includes:
· Heart: The role of the heart is to provide cells with oxygen-rich blood. Blood is constantly moving through the body in one direction due to a system of valves, which are flaps of connective tissue. These valves are located between the atria, upper part of the chamber of the heart that receives blood, and the ventricles, the lower part that pumps blood out of the heart. The heart is able to constantly beat due to a series of muscles in the heart.

· Arteries: Arteries are large vessels that carry blood from the heart to the tissues of the body.
· Capillaries: Capillaries are the smallest blood vessels. Their thin walls allow oxygen and nutrients to diffuse into the tissues while the carbon dioxide and waste products move into the blood.
· Veins: Veins transport blood back to the heart after it passes through the capillaries.
