All will be able to:
Recall the three main types of blood vessel and some functions of the blood.
Most should be able to:
Describe the function of each blood vessel and part of the blood.
Some could be able to:
Link the structure of blood vessels to their function.

Write the date and title and underline.
Draw the flow diagram on a whole page.
Around “BLOOD” on your flow diagram, write the parts of the blood and their
function.
Underneath “ARTERIES,” “VEINS” and “CAPILLARIES”, write down their function.
Complete the table comparing veins and arteries.
In your books explain:
1. Why arteries have thicker walls.
2.Why veins have valves.
3.Why capillaries have thin walls.

All: Recall the three main types of blood vessel and some
functions of the blood.
Most: Describe the function of each blood vessel and part of
the blood.
Some: Link the structure of blood vessels to their function.
Arteries
Carry blood away from
the heart; divide to form
smaller arterioles
Veins
Carry blood towards the
heart; small veins are
called venules
Capillaries
Link arterioles and
venules together and are
small, microscopic
vessels.

Arteries
Blood in arteries travels away
from the heart, and towards
organs.
It travels at high pressure and
is usually oxygenated.
The artery has thick muscular
walls to withstand the high
pressure.

Most: Describe the function of each blood vessel and part of the blood.
Some: Link the structure of blood vessels to their function.
Veins
Veins take blood to the heart and
away from organs.
Blood travels at low pressure so
veins have valves to prevent
blood going backwards.
The blood inside veins is usually
deoxygenated.

Most: Describe the function of each blood vessel and part of the blood.
Some: Link the structure of blood vessels to their function.
Capillaries
Capillaries are microscopic
vessels that connect
arterioles to venules.
They are only 1 cell thick
and allow substances to
be exchanged between
blood and body cells.
The liquid part of the blood
is called plasma and
contains many dissolved
substances (solutes)
essential for cell
metabolism.

Arteries
Carry blood away from the heart.
Return blood to the heart
Have thicker walls.
Have a wider lumen.
Blood spurts when cut due to higher
pressure.
Blood moves more slowly due to lower
pressure.
Have valves.
Blood is bright red.
Blood contains less O2.
