20
Q

What are cemented joints?

A

Cemented joints are joints that are attached to the bone and held in place by a mixture applied to the surface.

21
Q

What are uncemented joints?

A

Uncemented joints are joints that are held in place by the growth of the bone that connects to the joint.

22
Q

What does the respiratory system consist of?

A

The respiratory system consists of the trachea, bronchi, alveoli, and capillary network.

23
Q

What is the trachea?

A

The trachea is the long tube connecting the pharynx, mouth and nasal cavities to the bronchi.

24
Q

What is the bronchi?

A

The bronchi is the organ that connects the trachea to the lungs.

25
Q

What is the alveoli?

A

The alveoli is the gaseous exchange zone of the lung.

26
Q

What is the capillary network?

A

The capillary network is a network of fine blood vessels.

27
Q

What is cardio-pulmonary resuscitation (CPR)?

A

CPR is a combination of expired air resuscitation and external cardiac compression.

28
Q

What are artificial lungs?

A

Artificial lungs are devices that operate on the same principles as natural lungs, but from external perspective.

29
Q

What is life support?

A

Life support is considered to be any type of therapeutic technique or device used to maintain life function.

30
Q

What is non-invasive surgery?

A

Non-invasive surgery refers to surgical techniques that make no incision in the skin at all.

31
Q

What is minimally invasive surgery?

A

Minimally invasive surgery refers to surgical techniques that require only a small practical incision to be made in the skin.

32
Q

What is keyhole surgery?

A

Keyhole surgery is a minimally invasive surgical technique that is carried out with special instruments including fibre optics.

33
Q

What are X-rays?

A

X-rays are non-invasive surgical techniques that scan the body and produce 2D images of the bones and joints within the body.

34
Q

What is ultrasound?

A

Ultrasound is a form of non-invasive surgery that projects (ultra)sound waves onto tissue, capturing and registering images as waves are reflected.

35
Q

What is thermography?

A

Thermography is a non-invasive surgical technique that maps and quantifies changes in the skin surface temperature.

36
Q

What are pins?

A

Pins are versatile implants used for the fixation of bone fragments.

37
Q

What are artificial joints?

A

Artificial joints are joints that replicate the natural joint that is damaged or no longer functioning.

38
Q

What are artificial pacemakers?

A

Artificial pacemakers are battery operated devices that are designed to mimic and replace the function of the natural pacemaker, controlling the heart rate.

39
Q

What are artificial valves?

A

Artificial valves are valves that are designed to replicate the natural valve, replacing them when damaged, ensuring unidirectional blood flow.

40
Q

What are crowns?

A

Crowns are tooth caps that are placed over an artificial or natural root system.

41
Q

What are dentures?

A

Dentures are removable plates or frames often used in false teeth.

42
Q

What are prosthetic limbs?

A

Prosthetic limbs are artificial replacements for entire limbs, or part limbs on amputees.

43
Q

What are cochlear implants?

A

Cochlear implants are artificial hearing devices that replace a cochlea when damaged.

44
Q

What are screws?

A

Screws are devices that are used to fix plates to bones.

45
Q

What are plates?

A

Plates are devices used to be strong and absorb large stress forces generated by movement in fractured bones.
