What are the top chambers called?1 Atria (more than one atrium) Ventricles Aortas Describe the role of the bicuspid valve in the cardiac cycle (2 marks)2This is a practice exam question. The question says DESCRIBE but is worth 2 marks. This means you need to make 2 points but each one is only brief. This question includes the CARDIAC CYCLE, so this must be referred to in the answer. During the ventricle contracts closing the bicuspid valve (1) and prevents the back flow of oxygenated blood in to the left atrium (1) State one function of the pulmonary vein (1 mark)1This is a practice exam question. The question says STATE, this means one simple point needs to be made Carries blood from the lungs to the side of the heart (1) What are the function of valves?1 Prevent the projection of blood Increase the back flow of blood Prevent the back flow of blood Increase the projection of blood State one function of the aorta (1 mark)1This is a practice exam question. The question says STATE, this means one simple point needs to be made Carries blood away from the heart to the (1) Which blood vessel carries deoxygenated blood back to the heart from the body?1 Pulmonary Artery Vena Cava Pulmonary Vein Aorta What are the bottom chambers called?1 Vena Cavas Ventricles Aortas Atria Describe the systole phase of the cardiac cycle (4 marks)4This is a practice exam question. The question says DESCRIBE but is worth 4 marks. This means you need to make 4 points but each one is only brief. The atria contract (1) and blood moves into the ventricles (1). The contract (1) and eject blood into the aorta and pulmonary artery (1) Describe the function of the tricuspid valve (2 marks)2This is a practice exam question. The question says DESCRIBE but is worth 2 marks. This means you need to make 2 points but each one is only brief. The function of the valve is to prevent the of blood (1) from the right ventricle into the right atrium (1). During ventricular systole……….1 The bicuspid and tricuspid valves open, the semi-lunar valves close and blood moves into the ventricles The bicuspid and tricuspid valves close, the semi-lunar valves open and blood moves out of the heart The bicuspid and tricuspid valves close, the semi-lunar valves close and blood moves into the atrium How many chambers, blood vessels and valves are there?1 3 2 4 Which blood vessel carries oxygenated blood to the body?1 Pulmonary Artery Vena Cava Pulmonary Vein Aorta Where does the pulmonary artery carry blood to and the pulmonary vein carry blood from?1 Body Heart Lungs What side of the heart would you find the tricuspid valve?1 Right Left
