Coding Lesson 07
Medical Coding Lesson 07 - Respiratory System
Term | Definition |
---|---|
Inspiration | Air goes into the lungs when the diaphragm and intercostal muscles contract. |
Expiration | Air is forced out of the lungs when the diaphragm and intercostal muscles relax. |
Mucous | membrane A thin layer of tissue that produces mucus. |
Mucus | A sticky substance that traps particulates and prevents them from traveling through the respiratory system. |
Cilia | Microscopic hairs that move particulates trapped in mucus out of the respiratory system. |
Pharynx | More commonly known as the throat. |
Larynx | More commonly known as the voice box or glottis. |
Trachea | More commonly known as the windpipe. |
Bronchi | Small air passages that are lined with mucous membranes and lead to the lungs. |
Bronchioles | Very small airways that lead to the alveoli. |
Alveoli | Air sacs at the end of the bronchioles that exchange oxygen and carbon dioxide in the blood. |
COPD | Chronic Obstructive Pulmonary Disease |
RSV | Respiratory Syncytial Virus |
SARS | Severe Acute Respiratory Syndrome |
Axial skeleton | The trunk of the body (excluding arms and legs) |
Cervical | Uppermost area of spine (top seven vertebrae) |
Coccyx | Lower tip of the spine |
Diaphysis | The shaft part of a long bone |
Distal skeleton | Bones farthest from the axial skeleton (lower arms, lower legs, hands, feet) |
Epiphysis | The knob end of a long bone |
Intervertebral disc | A cartilage cushion between vertebrae in the spine |
Lumbar | Spine of the lower back (five vertebrae below thoracic) |
Metaphysis | Where the diaphysis joins the epiphysis |
Proximal skeleton | Bones closest to the axial skeleton (upper arms and legs) |
Sacrum | Vertebrae within the pelvic girdle, which fuse in late teen years |
Thoracic | Spine of the upper body (middle 12 vertebrae) |
Vertebra | A cylindrical bone of the spinal column, enclosing the spinal cord |
Flexors | Muscles that contract or bend at the joint |
Extensors | Muscles that extend at the joint (opposite of flexors) |
Abductors | Muscles that move body parts away from the trunk |
Adductors | Muscles that move body parts toward the trunk |
Greenstick | Incomplete fracture (think of breaking a tree branch that's still green) |
Closed | Simple, complete |
Open | Compound |
Impacted | Telescoped |
Spiral | The break encircles the bone in a spiral shape |
Comminuted | The bone is broken, splintered or crushed in several pieces |
