Understand gas exchange (of carbon dioxide and oxygen) in relation to respiration and photosynthesis
Understand how the structure of the leaf is adapted for gas exchange
Describe the role of stomata in gas exchange
Understand how respiration continues during the day and night, but that the net exchange of carbon dioxide and oxygen depends on the intensity of light
Describe the structure of the thorax, including the ribs, intercostal muscles, diaphragm, trachea, bronchi, bronchioles, alveoli and pleural membranes
Understand the role of the intercostal muscles and the diaphragm in ventilation
Explain how alveoli are adapted for gas exchange by diffusion between air in the lungs and blood in capillaries

Understand why simple, unicellular organisms can rely on diffusion for movement of substances in and out of the cell
Understand the need for a transport system in multicellular organisms
Describe the role of phloem in transporting sucrose and amino acids between the leaves and other parts of the plant
Describe the role of xylem in transporting water and mineral ions from the roots to other parts of the plant
Understand how water is absorbed by root hair cells
Understand that transpiration is the evaporation of water from the surface of a plant
Understand how the rate of transpiration is affected by changes in humidity, wind speed, temperature and light intensity
Describe the composition of the blood: red blood cells, white blood cells, platelets and plasma
Understand the role of plasma in the transport of carbon dioxide, digested food, urea, hormones and heat energy
Understand how adaptations of red blood cells make them suitable for the transport of oxygen, including shape, no nucleus and the presence of haemoglobin
Understand how the immune system responds to disease using white blood cells, illustrated by phagocytes ingesting pathogens and lymphocytes
Understand how vaccination results in the manufacture of memory cells, which enable future antibody production to the pathogen to occur sooner
Understand how platelets are involved in blood clotting, which prevents blood loss and the entry of micro-organisms
Describe the structure of the heart and how it functions
Explain how the heart rate changes during exercise and under the influence of adrenaline
Understand how factors may increase the risk of developing coronary heart disease
Understand how the structure of arteries, veins and capillaries relate to their function
Understand the general structure of the circulation system, including the blood vessels to and from the heart and lungs, liver and kidneys
Understand the origin of carbon dioxide and oxygen as waste products of metabolism and their loss from the stomata of a leaf
Know the excretory products of the lungs, kidneys and skin (organs of excretion)
Understand how the kidney carries out its roles of excretion and osmoregulation
Describe the structure of the urinary system, including the kidneys, ureters, bladder and urethra
Describe the structure of a nephron, including the Bowman's capsule and glomerulus, convoluted tubules, loop of Henle and collecting duct
Describe ultrafiltration in the Bowman's capsule and the composition of the glomerular filtrate
Understand how water is reabsorbed into the blood from the collecting duct
Understand why selective reabsorption of glucose occurs at the proximal convoluted tubule
Describe the role of ADH in regulating the water content of the blood
Understand that urine contains water, urea and ions
Understand how organisms are able to respond to changes in their environment
Understand that homeostasis is the maintenance of a constant internal environment, and that body water content and body temperature are both examples
Understand that a co-ordinated response requires a stimulus, a receptor and an effector
Understand that plants respond to stimuli
Describe the geotropic and phototropic responses of roots and stems
Understand the role of auxin in the phototropic response of stems
Describe how nervous and hormonal communication control responses and understand the differences between the two systems
Understand that the central nervous system consists of the brain and spinal cord and is linked to sense organs by nerves
Understand that stimulation of receptors in the sense organs sends electrical impulses along nerves into and out the CNS results in rapid responses
Understand the role of neurotransmitters at synapses
Describe the structure and functioning of a simple reflex arc illustrated by the withdrawal of a finger from a hot object
Describe the structure and function of the eye as a receptor
Understand the function of the eye in focusing on near and distant objects, and in responding to changes in light intensity
