Question | Answer |
---|---|
Aorta | The largest artery in the human body, diverts oxygenated blood throughout the body |
Artery | Blood vessels that carry oxygenated blood away from the heart and into the body |
Atrium | The chamber of the heart where deoxygenated blood first enters the heart |
Bicuspid valve | Made from two aortic valvular leaflets, it ensures the unidirectional flow of blood from the atrium to the ventricles, found on the left side of the heart |
Biomaterial | Is any matter, surface or construct that interacts with biological systems |
Biomedical | The application of the principles of the natural sciences to medicine |
Bionic | Having certain physiological functions augmented or replaced by electronic equipment |
Bradyarrhythmia | Deterioration in the heart’s own pacing system |
Bradycardia | AV junction in the heart fails to transmit the electrical signals the ventricles don’t contract and you get a very slow heart rate under 40 bpm |
capillary | Any of the fine branching blood vessels that form a network between The smallest thin-walled blood vessels connecting arteries to veins |
cardiac | Relating to the Heart |
cardiac arrest | The heart is fibrillating as a result of the unsequenced cardiac contractions |
cardiopulmonary resuscitation | Emergency procedure in which heart and lungs are made to work through compressions, to circulate needed blood to the brain |
complete heart block | When the AV junction fails to transmit electrical signals to the ventricles due to a failure |
defibrillator | Apparatus used to control heart fibrillation by application of an electric current. |
electrocardiograph | An instrument used in the detection and diagnosis of heart abnormalities that measures electrical potentials on the body surface and generates a record of the electrical currents associated with heart muscle activity |
fibrillation | Atrial fibrillation is a type of heart irregularity. The heart quivers rather than contracts, both fast and abnormally slow and this can cause palpitations or a fluttering heartbeat, irregular heartbeat, chest pains, dizziness or fainting spells |
heart transplant | A heart or cardiac transplant, is a surgical transplant procedure performed on patients with end-stage heart failure or severe coronary artery disease |
heart valve | A heart valve normally allows blood flow in only one direction through the heart. A heart valve opens or closes incumbent upon differential blood pressure on each side |
pacemaker | Delivers electrical impulses to the heart when the heart skips a beat |
sinus node | A group of cells located in the right atrium which sends electrical impulses causing the heart chambers to contract |
stethoscope | Instrument that amplifies sound such as the heartbeat |
tachyarrhythmia | An overly rapid heartbeat |
tricuspid valve | The function of the valve is to prevent backflow of blood into the right atrium |
vein | Blood vessels that carry blood toward the heart |
ventricle | Two large chambers that collect and expel blood received from an atrium |
ventricular tachycardia | Is a type of rapid heartbeat, that starts in the bottom chambers of the heart. Can prevent the heart from filling with blood between beats |
Collagen | The main structural protein of the various connective tissues in animals mostly found in fibrous tissues such as tendons, ligaments and skin |
Ligaments | Holds two bones together and keep the joints from moving |
Tendons | Fibrous bands of connective tissue that join the muscle to the bone |
Synovial fluid | Lubricant between joints |
Cartilage | Made up of tough flexible protein fibers which form a smooth , frictionless surface around a joint or the support for structures |
