What is mass transport?
This is the bulk movement of substances from a
region of high pressure to a region of low
pressure in the transport system.…read more

The blood vessels
Arteries = transport blood away from the heart
Arterioles = small arteries
Capillaries = allow exchange of materials into
and out of the blood
Veins = transport blood back to the heart
Venules = small veins…read more

Structure related to function...
1) Endothelium = this is the smooth lining next
to the blood which reduces friction between
the blood and the wall
2) Middle layer = this contains elastic tissue and
smooth muscle
3) Outer layer = this contains the tough fibrous
protein collagen…read more

· These have the thickest walls as they are
responsible for carrying blood under high pressure
without bursting.
· They also have the most elastic tissue in the
middle layer which allows them to dilate and
accomodate the increase in blood when the
ventricle contracts.
· After the ventricle contracts, the arteries recoil.
This maintains blood pressure and helps to
smooth out the flow of blood to the capillaries.…read more

· These have less elastic tissue
· They have more muscle in the middle layer to
control the flow of blood
· When the muscle contracts, the arterioles get
narrower (lumen narrows) reducing the flow
of blood.…read more

This is absolutely brilliant! It's a nice way for me test my understanding 4 hours before the exam :D !
