Skeletal System 1 Flashcards
(20 cards)
what are the 5 functions of the skeleton
support/shape, protection, movement, blood cell production, mineral storage
what is the skeleton
a rigid bone frame that gives the body shape
what does the skeleton support
soft tissues like skin and muscle
why is the skeleton essential in sport
the shape helps you to have good posture
give an example of support/shape in sport
good posture helps performance in gymnastics
what do bones protect
bones protect vital organs such as the brain, heart and lungs
how does protection impact sport
allows athletes to perform well without fear of serious injury
give an example of protection in sport
the cranium protects the brain so you can head a football without serious injury
what can move bones at joints
muscles that are attached to bones by tendons
how does movement impact sport
bone movement is essential for good performance
what do bones contain which makes the components of blood
bone marrow makes red and white blood cells
why are red blood cells important during exercise
they transport the oxygen that muscles need to move
why do athletes with more red blood cells perform better
more oxygen can be delivered to their muscles
what do bones store
minerals such as calcium and phosphorus
what do minerals help with
bone strength so you’re less likely to break a bone
what are minerals needed for
muscle contraction so the body can move
what is the purpose of long bones
enable gross movements
what is the purpose of short bones
enable fine movements
what is the purpose of flat bones
to protect internal organs
what allows for muscle attachment
the broad surface of flat bones
