Medical Technology - Bionics: Terminology Flashcards
What is the function of the atria?
Receives blood from the veins and passes it on to the ventricles.
What does the heart consist of?
The heart consists of valves, atria, ventricles, and major arteries and veins.
The sinoatrial node (or sinus node) is meant to serve what purpose?
The sinus node acts as a natural pacemaker, sending electrical signals directly to the atria.
What is the purpose of the capillary network?
The capillary network absorbs the fore of the heartbeat.
What is arrhythmia?
Arrhythmia is an irregular heartbeat.
What is bradycardia?
Bradycardia occurs when the heartbeat is too slow.
What is tachycardia?
Tachycardia occurs when the heartbeat is too fast.
What is fibrillation, and how is it treated?
Fibrillation is an irregularity in the heartbeat, often resolved by the use of a defibrillator.
What is a pacemaker?
A pacemaker is the natural controller of the heart and its functions.
What are faulty valves?
Faulty valves are valves that no longer function or do not function properly.
What are thrombolytic agents?
Thrombolytic agents are clot-dissolving medication that are often consumed orally.
What is angioplasty?
Angioplasty is the process of removing plaque through the inflation of balloons inside the blood vessel.
What is atherectomy?
Atherectomy is the process of mechanically removing plaque through the use of a catheter.
What does the skeletal system consist of?
The skeletal system consist of the appendicular and axial skeletons.
What is the appendicular skeleton?
The appendicular skeleton is the supporting structure of the appendices, including the pelvic griddle, shoulders, and arms and legs.
What is the axial skeleton?
The axial skeleton is the upper skeletal structure that consist of the skull, spinal cord, sternum, and ribs.
What are synovial joints?
Synovial joints are freely moving joints, with spaces between the bones forming the joint.
What is cartilage?
Cartilage is a tough and fibrous substance that is between the bone ends in some joints.
What is synovial fluid?
Synovial fluid is fluid that acts as lubricant in larger bones.
What are cemented joints?
Cemented joints are joints that are attached to the bone and held in place by a mixture applied to the surface.
What are uncemented joints?
Uncemented joints are joints that are held in place by the growth of the bone that connects to the joint.
What does the respiratory system consist of?
The respiratory system consists of the trachea, bronchi, alveoli, and capillary network.
What is the trachea?
The trachea is the long tube connecting the pharynx, mouth and nasal cavities to the bronchi.
What is the bronchi?
The bronchi is the organ that connects the trachea to the lungs.
