What Body Systems and Physiological Disorders covers

Body Systems and Physiological Disorders is examined in Unit A2 2, Body Systems And Physiological Disorders — compulsory for the Double Award; one of four options for the Single Award. It covers the heart and the cardiac cycle, blood, blood vessels and the double circulation, control of heart rate and blood pressure, the respiratory system, ventilation and gas exchange, behaviour that protects the heart and lungs, normal ranges for pulse and breathing rates, and causes of deviation, monitoring pulse and breathing safely before and after exercise, presenting and analysing monitoring results, coronary heart disease, asthma and other physiological disorders, diagnostic techniques and what each one shows, treatments, care pathways, practitioners and support services and the effects of a physiological disorder on everyday life.

Questions from this topic

Each one with the model answer underneath.

  1. 1

    Name the four chambers of the human heart.

    Model answer

    The human heart has a right atrium, a right ventricle, a left atrium and a left ventricle.

  2. 2

    Which side of the heart pumps blood to the lungs, and through which vessel?

    Model answer

    The right side of the heart pumps deoxygenated blood to the lungs through the pulmonary artery.

  3. 3

    Explain why the wall of the left ventricle is the thickest part of the heart.

    Model answer

    The left ventricle has the thickest muscular wall because it must generate enough pressure to drive blood all the way round the body.

  4. 4

    What is the function of the septum?

    Model answer

    The septum is the muscular wall dividing the two sides of the heart, and it keeps oxygenated and deoxygenated blood from mixing.

  5. 5

    What do the atrioventricular valves do?

    Model answer

    The atrioventricular valves sit between each atrium and its ventricle and stop blood being forced back into the atria when the ventricles contract.

  6. 6

    Name the valve between the left atrium and the left ventricle.

    Model answer

    The bicuspid valve, also called the mitral valve, lies between the left atrium and the left ventricle.
