5 Questions
What is the blood circulatory system?
The blood circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate.
What is the cardiovascular system?
The cardiovascular system consists of the heart and blood vessels.
What are the two divisions of the circulatory system?
The circulatory system has two divisions: systemic circulation or circuit, and pulmonary circulation or circuit.
What are the great vessels of the heart?
The great vessels of the heart include large elastic arteries and large veins.
What is the difference between the circulatory system in vertebrates and invertebrates?
The circulatory system is closed in vertebrates, meaning the blood never leaves the network of blood vessels, while invertebrates like arthropods have an open circulatory system.
Study Notes
The Blood Circulatory System
- Includes the heart, blood vessels, and blood that is circulated throughout the entire body of a human or other vertebrate
- Comprises the cardiovascular system, or vascular system, which consists of the heart and blood vessels
Divisions of the Circulatory System
- Systemic circulation or circuit
- Pulmonary circulation or circuit
Blood Vessels
- The network of blood vessels includes:
- Great vessels of the heart
- Large elastic arteries
- Large veins
- Arterioles
- Capillaries
- Venules (small veins)
- Other veins
Characteristics of the Circulatory System
- Closed circulatory system in vertebrates, meaning blood never leaves the network of blood vessels
- Open circulatory system in some invertebrates, such as arthropods
