Transcript of Revision

Skeletal System Muscular System Cardiovascular System Revision Muscle can be classified as
skeletal, cardiac or smooth.
Muscle movements can be involuntary
(without concious thought) like the
contraction of the heart or peristalsis
which pushes food through the
digestive system. There are two types of muscle fibres, slow and fast twitch.
Slow twitch can contract for long periods, but with little force, whereas fast twitch contract quickly and powerfully, but fatigue very rapidly. We have 206 bones in our body.
The longest bone is the Femur and the
shortest bone is the stapes.
The skeleton is divided into two sections,
the axial and the appendicular skeleton. The axial skeleton is the bones in the middle
of the body. It's main functions are protection,
support and storage.
The appendicular skeleton consists of our limbs
and attachment points. Their main functions are
to provide movement, storage and manufacture
red blood cells. The main components of the circulatory
system are the heart, the blood and the
blood vessels.
Together they move substances to and
from cells, stabilise body temperature
and pH. The heart beats approximately 70 times
per minute at rest. If you are stressed,
scared, excited, ill, or exercising your
heart beat will rise.
