What Understanding the Physiology of Health and Illness covers

Understanding the Physiology of Health and Illness is examined in Unit AS 7, Understanding The Physiology Of Health And Illness — a Double Award option, taken instead of AS 5. It covers the animal cell and its organelles, cell specialisation and the four tissue types, the organisation of the nervous system, the major areas of the brain, neurones, the reflex arc and the synapse, multiple sclerosis, spinal cord injury and stroke, the endocrine glands and their hormones, type 1 and type 2 diabetes, the digestive system and how food is broken down, pancreatitis, cirrhosis of the liver and stomach ulcers, the urinary system and the kidney nephron, renal failure, incontinence and dehydration and living with a physiological disorder.

Questions from this topic

Each one with the model answer underneath.

  1. 1

    What is the function of the cell membrane?

    Model answer

    The cell membrane encloses the cell and controls which substances enter and leave it.

  2. 2

    Describe the structure of the cell membrane.

    Model answer

    The cell membrane is a double layer of phospholipid molecules with proteins embedded in it, an arrangement described as a fluid mosaic.

  3. 3

    What does the nucleus do?

    Model answer

    The nucleus holds the cell's DNA and controls the cell's activities, including protein synthesis and cell division.

  4. 4

    What is the nucleolus and what is it for?

    Model answer

    The nucleolus is a dense region inside the nucleus that makes ribosomes.

  5. 5

    Which organelle releases most of a cell's energy, and how?

    Model answer

    Mitochondria release most of a cell's energy by aerobic respiration, transferring it to ATP.

  6. 6

    Why do muscle cells contain large numbers of mitochondria?

    Model answer

    Muscle cells contract repeatedly and need a great deal of ATP, so they carry large numbers of mitochondria to supply it.
