8 The diаgrаms shоw sectiоns thrоugh аn artery and a vein. (see addendum Question 8, Figure 8.1) 8.1 Use the information in the diagrams and your own knowledge to give three ways in which the structure of an artery differs from the structure of a vein. (3) 8.2 Lack of movement by sitting still for long periods of time makes blood flow very slowly in a vein. Blood that flows slowly is more likely to clot than blood that flows normally. This problem is known as deep vein thrombosis (DVT). In DVT, the clot usually occurs in a leg vein as shown in the diagram. (see addendum Question 8, Figure 8.2) DVT is dangerous because sometimes part of the clot breaks off and travels to the lung, blocking small blood vessels and causing death. 8.2.1 Suggest why blood flow in a leg vein is slow when there is lack of movement. (2) 8.2.2 Name the blood cells responsible for transporting oxygen. (1) 8.2.3 Suggest why a clot that blocks the small blood vessels in the lungs can cause death. (2) 8.3 Explain why the muscle in the atria is less than in the ventricle. (1)
