Study Notes
Circulatory System Divisions
- The two divisions of the circulatory system are the pulmonary circulation and the systemic circulation.
Closed Circulatory System in Vertebrates
- In vertebrates, the circulatory system is closed, meaning that the blood is contained within blood vessels and is circulated throughout the body in a closed loop.
Open Circulatory System in Invertebrates
- Some invertebrates, such as arthropods, have an open circulatory system, where the fluid (hemolymph) bathes the internal organs directly.
Cardiovascular System Components
- The cardiovascular system consists of the heart, blood vessels, and blood.
Great Vessels of the Heart
- The great vessels of the heart are the aorta, pulmonary arteries, and pulmonary veins, which are part of the network of blood vessels that transport blood throughout the body.
