Study Notes
Cardiovascular System Terminology
- aort/o: Refers to the aorta, the largest artery in the body.
- arteri/o: Denotes an artery, a blood vessel carrying blood away from the heart.
- ather/o: Indicates plaque or fatty substances typically found in arteries.
- angi/o: Pertains to blood or lymph vessels.
- brady-: A prefix meaning slow, often used to describe heart rates.
- -emia: A suffix relating to blood or blood conditions, commonly used in medical terms.
- cardi/o: The term for heart, central to the cardiovascular system.
- coron/o: Refers to crown or coronary, typically related to heart blood supply.
- erythr/o: Signifies red, often associated with red blood cells.
- ech/o: Means sound, used in medical imaging.
- leuk/o: Represents white, usually in reference to white blood cells.
- phleb/o: Relates to veins, which carry blood back to the heart.
- tachy-: A prefix meaning fast or rapid, often used for heart rates.
- thromb/o: Refers to clot, important for understanding blood coagulation.
- hem/o: Pertains to blood, integral in discussing blood conditions.
Key Physiological Terms
- leukocytes: White blood cells crucial for immune response.
- sinoatrial node: Known as the natural pacemaker of the heart, regulating heartbeat.
- coronary arteries: Supply blood to the myocardium (heart muscle).
- echocardiography: Ultrasound technique to assess heart structure and motion.
- mitral valve: Also known as the bicuspid valve, controlling blood flow between left atrium and ventricle.
- right ventricle: Pumps blood into the pulmonary artery to send it to the lungs.
- thrombocytes: Smallest blood components, essential for clotting.
- embolus: A circulating foreign object in the bloodstream, which can cause blockages.
Heart Structure and Function
- heart: A hollow, muscular organ responsible for pumping blood.
- myocardium: The thick middle layer of heart muscle that contracts.
- epicardium: The outermost layer of the heart.

- bradycardia: A condition characterized by an abnormally slow heart rate.
- fibrillation: Rapid, random heart contractions leading to ineffective pumping.
- systolic pressure: The highest pressure in arteries when the heart ventricles contract.
- leukopenia: A decrease in white blood cell count, affecting immunity.
- aneurysm: A potentially fatal condition where a blood vessel bulges and may rupture.
