small intestine
horses eat a lot of fibre and so need a lot of bile to digest it
15-22m long
Horses do not have a gall bladder, so bile flows constantly.
Most food is digested and absorbed into
the bloodstream from the small intestine,
including proteins, simple carbohydrate,
fats, and vitamines A, D, and E
The trachea is the tube
which carries air into the
lungs, and is about 75–80
cm in length in the adult.
It is held permanently open
by 50-60 "C"-shaped rings of
cartilage, 5–6 cm in diameter
heart
4 chambers and average of 3.9kg with vessels
heart rate range from 20 – 240 beats
per minute and a splenic red cell reserve
able to double packed cell volume and
oxygen delivery during maximal exercise
THIS IS WHY YOU MUST COOL DOWN PROPERLY OTHERWHISE YOUR HORSES HEART LITERALLY EXPLODES WITH THE PRESSURE!!!
The circulatory system
the hoof
. As the horse puts weight
onto the hoof, the hoof
wall is pushed outwards
and the frog compressed,
driving blood out of the
frog, the digital pad, and
the laminae of the hoof
When weight is removed
from the hoof, the release of
pressure pulls blood back
down into the foot again. This
effectively creates an
auxiliary blood-pumping
system at the end of each leg
