We will start off by just dividing the animal into these regions and cavities.
First region, I think you'll find relatively easy,
so this is the head.
So the heads contains a few cavities, for example,
the oral cavity, or have the nasal cavity within it.
And the head is attached to the rest of the body by the neck,
so in us the neck is quite a small, short structure.
And a lot of the animals we concern with,
the head could be quite a lot more substantial because when you stand on four legs,
you sometimes can end up with quite heavy head at the end of your neck that
you need to be able to support.
I don't think you'll struggle with this part either.
So, we call this the forelimbs,
so and equivalent are our arms.
That's the forelimb and here we have a hindlimb.
So, all these regions
are attached to the main bulk of the body which is made up of the trunk.
I'll just outline the trunk there for you.
So, this would be the trunk.
And we then can divide the trunk into further cavities.
So, we got a thoracic cavity or the thorax,
this is where your heart and lungs are well protected behind the rib cage.
And then you have caudal after that,
you have the abdomen where you can find,
for example, the digestive tract.
And the last area here would be your pelvic cavity or your pelvis.
That's the main regions and body cavities that we have.
