|---|---|---|---|---|---|
| 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
🗑

||||
| 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
🗑

🗑
|
||||
| cardiopulmonary resuscitation | Emergency procedure in which heart and lungs are made to work through compressions, to circulate needed blood to the brain
🗑
|
||||

🗑
|
||||
| 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

🗑
|
||||
| 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
🗑
|
||||

🗑
|
||||
| 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
🗑
