Welcome to Physiology

Physiology is a topic that looks at the function of living things, it is very broad and covers the biology of humans, plants and investigates many important topics including:

  • Transport of water in plants
  • Circulatory systems and how heartbeat is controlled
  • The structure and functioning of the eye.

    • Use the navigation table below to find your way around this section.

    Heart and LungsDiagram of heart, the hearbeat and pressure changes, breathing control.
    Blood and Blood VesselsBlood vessles, haemoglobin, oxygen dissociation curve, capillary pressure.
    Energy and ExerciseATP structure, aerobic and anaerobic respiration comparison and muscle fatigue.
    Water in PlantsSymplast and apoplast, cohesion-tension theory, and xerophytic plant adaptations.
    Roots and TranslocationStructure of primary roots, translocation and mass flow and evidence from ringing and tracers.
    HomeostasisHormones in homeostasis, negative feedback, body temperature, blood glucose.
    The KidneyUrea production, the proximal convoluted tubule, the loop of Henle and ADH regulation.
    The EyeStructure of the eye; focusing (iris, ciliary muscles); rod and cone cells (strucutre, functioning)
    The Nervous SystemReflex arc; stages of an impulse and action potential; synaptic transmission.
    RespirationStructure of mitochondrion. Glycolysis, link reaction, Krebs Cycle and the electron transfer chain.
    PhotosynthesisStructure of chloroplast, light dependent reaction and light independent reaction (Calvin cycle).
    The BrainThe cerebral hemispheres and different association areas, actions of autonomic nervous system.
    MusclesThree types of muscle, structure, sarcomere banding, sliding filament hypothesis of contraction.
