1) The three different blood vessels are arteries, veins and capillaries. The incomplete flow diagram below shows the order of blood vessels that blood passes through as it leaves the heart and then returns to the heart.

a) Fill in the gaps.
b) Which of the 3 blood vessels have permeable walls?
c)
i) Which of the 3 blood vessels have valves?
ii) Explain the role that the valves play in this blood vessel.
2) Draw the cross sections of an artery and a vein. Label the interesting parts of your cross sections.
3) The very simple diagram below shows both of the circulatory systems.

2) Draw the cross sections of an artery and a vein. Label the interesting parts of your cross sections.
3) The very simple diagram below shows both of the circulatory systems.
There are 4 different blood vessels on the diagram, which are labelled 1 to 4. Say which ones are arteries and which ones are veins.
Extension – give the names of the four different blood vessels

4) The diagram below shows the cross sections of an artery and a vein.
a) Why are the walls of elastic fibres and muscle tissue thicker in an artery than a vein?
b) Why do veins have a larger lumen than arteries?
5)
a) Capillaries have permeable walls that are only one cell thick. Explain how this helps capillaries to carry out their function.
b) Give 3 substances that diffuse into or out of capillaries.
6) 1,764 ml of blood passes through an artery in 4.5 minutes. Find the rate of blood flow through this artery giving your answer in ml/min.
7) 7,276 ml of blood passes through an artery in 17 minutes. Find the rate of blood flow through this artery giving your answer in ml/min.
8) The rate of blood flow through an artery is 314 ml/min. Calculate the volume of blood that passes through this artery in 12 minutes. Give your answer in ml.
