Questions and Answers
What is the function of the cardiovascular system?
The cardiovascular system consists of the pump and vessels that distribute blood to all areas of the body, allowing for the delivery of needed substances to the cells of the body as well as for the removal of wastes.
What are the organs of the cardiovascular system?
Blood vessels (arteries, capillaries, veins) and the heart.

Study Notes
Cardiovascular System Overview
- The cardiovascular system comprises the heart and blood vessels, facilitating blood distribution throughout the body.
- Its primary functions include delivering essential substances to cells and removing waste products.
Key Components of the Cardiovascular System
- Organs involved are blood vessels (arteries, veins, capillaries) and the heart itself.
Terminology Related to Blood Vessels
- angi/o: Refers to vessels; commonly used in medical terms related to blood vessels.
- aort/o: Pertains specifically to the aorta, the main artery of the body.
- arteri/o: Indicates arteries, blood vessels that carry blood away from the heart.
- phleb/o: Refers to veins, which carry blood toward the heart.
- vascul/o: Denotes blood vessels in general; a crucial part of the cardiovascular system.
Terms for Specific Conditions
- ather/o: Represents fatty substances, often associated with diseases like atherosclerosis.
- thromb/o: Indicates clots, which can obstruct blood flow in vessels.
- sthenosis: Refers to narrowing, vital in understanding conditions impacting blood flow.
Heart Anatomy and Related Terms
- cardi/o and coron/o: Both refer to the heart and are used in various cardiac-related medical terminology.
- myocardi/o: Specifically refers to heart muscle, essential for understanding heart function.
Diagnostic and Surgical Terms
- -ectomy: Indicates surgical removal, significant in various cardiac procedures.
- -gram: Refers to a record, commonly used in diagnostic imaging.
- -plasty: Indicates a surgical procedure, often involving repair or reconstruction.
- -itis: Signifies inflammation, relevant in diagnosing conditions like myocarditis.
Cardiovascular Procedures and Professionals
- A cardiovascular technician performs diagnostic and therapeutic procedures including ECGs and stress tests.
- Cardiology is the specialized branch of medicine focused on the cardiovascular system, with practitioners known as cardiologists.
Common Conditions of the Cardiovascular System
- angiitis: Refers to inflammation of blood vessels; understanding this term is crucial for identifying vascular diseases.
- angiospasm: Involuntary contractions of vessel walls, leading to narrowing of blood vessels.
Additional Key Vocabulary
- ventricul/o: Pertains to ventricles, the heart's lower chambers that pump blood.
- valv/o and valvul/o: Both refer to valves, essential for maintaining unidirectional blood flow.
- sept/o: Indicates a wall, often the cardiac septum separating chambers of the heart.
Important Prefixes and Suffixes
- brady-: Means slow, often used in context of heart rate.
- tachy-: Means fast, applicable to heart conditions with accelerated rates.
- hyper-: Indicates excessive; used in hypertensive conditions.
- hypo-: Signifies insufficient; relevant in conditions like hypotension.
- poly-: Refers to many; useful in classifying various conditions and anomalies.
Additional Notes
- The presence of terms like -megaly (enlarged) and -oma (growth) aids in understanding potential abnormalities within the cardiovascular system.
- Understanding these terms is essential for comprehensively grasping the various functions and conditions related to the cardiovascular system.
