What is a muscle or tendon
This life-saving technique uses chest compressions and rescue breaths to restore circulation.

This term describes a bone that has cracked or broken due to a force or impact.
What is a fracture

what is a wrist
Muscle strains are commonly classified into three of these levels based on severity.
What are grades (Grade 1, 2, and 3)?
In adult CPR, this is the recommended compression-to-breath ratio when no advanced airway is in place.
What is 30:2?
This device is commonly used to hold broken bones in place while they heal.
What is a cast (or splint)?
What does hemoglobin cart round the body
What is oxygen

what is the clavicle
When chemical is present when the bruise is brown
what is hemosiderin
This joint is most commonly affected by sprains in sport
This type of muscle contraction is most likely to cause a strain when the muscle lengthens under tension.
What is an eccentric contraction
This is the main purpose of chest compressions during resuscitation.
What is maintaining blood flow to the brain and vital organs
This biological process explains how broken bones repair themselves over time.
What is bone remodelling
What is the chemical released when the bruise is green?
Biliverdin
This loss of function occurs because damaged ligaments reduce joint stability and proprioception
What is decreased joint stability
This microscopic damage triggers inflammation, swelling, and reduced muscle contraction following a strain.
What is tearing of muscle fibres at a cellular level
This is why resuscitation becomes less effective the longer it is delayed after cardiac arrest.
What is prolonged oxygen deprivation leading to cell death
This specialised tissue produces new bone cells during fracture repair.
