- PROTOZOA-MALARIA
- FUNGI-ATHLETES FOOT
- A BALANCED DIET
- CARBOHYDRATES AND FATS TO PROVIDE ENERGY
- PROTEIN FOR GROWTH AND REPAIR
- MINERALS WHICH IS NEEDED TO MAKE HAEMOGLOBIN IN RED BLOOD CELLS
- VITAMINS TO PREVENT SCURVY
- FIBRE WHICH PREVENTS CONSTIPATION

- CARBOHYDRATES AND FATS TO PROVIDE ENERGY
- BMI
- BMI- mass (kg) divided by height (m)2 squared
- BMI- mass (kg) divided by height (m)2 squared
- BLOOD PRESSURE
- blood pressure is a measure of the force of blood per unit area as it flows through the arteries
- IT IS MEASURED IN mmHg which means millimetres of mecury
- IT IS MEASURED IN mmHg which means millimetres of mecury
- Blood pressure is at its highest when the heart muscle contracts forcing blood into the arteries to all parts of the body.
- THIS IS CALLED SYSTOLIC BLOOD PRESSURE
- THIS IS CALLED SYSTOLIC BLOOD PRESSURE
- When the heart relaxes the pressure in the arteries drops. THIS IS CALLED DIASTOLIC BLOOD PRESSURE
- blood pressure is a measure of the force of blood per unit area as it flows through the arteries
- THE NERVOUS SYSTEM
- A SENSORY NEURONE
- Carries nerve impulses from the receptors to the CNS
- Carries nerve impulses from the receptors to the CNS
- A RELAY NEURONE
- makes connections between neurones inside the brain and spinal cord
- makes connections between neurones inside the brain and spinal cord
- A MOTOR NEURONE
- Carries nerve impulses from the CNS to the muscles and glands
- Carries nerve impulses from the CNS to the muscles and glands
- the central nervous system is made up of the spinal cord and the brain
- light receptors in the retina of the eye detect light
- sound and change of position receptors in the ears (for balance)
- taste receptors on the tongue detect chemicals in food
- smell receptors in the nose detect chemicals in the air
- smell receptors in the nose detect chemicals in the air
- touch, pressure, pain and temperature receptors in the skin.
- EFFECTORS are the muscles or glands that make the change in response to the signal from the receptor
- EFFECTORS are the muscles or glands that make the change in response to the signal from the receptor
- sound and change of position receptors in the ears (for balance)
- REFLEX ACTION
- GIVE FAST AUTOMATIC RESPONSES TO STIMULUS HELPING TO PROTECT THE BODY FROM HARM.
- EXAMPLES
- knee jerk reaction
- withdrawing your hand from a hot plate to prevent burning yourself
- knee jerk reaction
- GIVE FAST AUTOMATIC RESPONSES TO STIMULUS HELPING TO PROTECT THE BODY FROM HARM.
- LONG SIGHT
- LONG SIGHT IS CAUSED BY AN EYE BALL THAT IS TOO SHORT OR BY A LENS THAT DOESNT SHAPE PROPERLY, IT CAN BE CORRECTED BY A CONVEX LENS WITH CONVERGES THE LIGHT RAYS FROM CLOSE OBJECTS SO THAT THEY FOCUS ON THE RETINA
- IS WHEN YOU CAN SE DISTANT OBJECTS CLEARLY BUT NOT CLOSE OBJECTS
- IS WHEN YOU CAN SE DISTANT OBJECTS CLEARLY BUT NOT CLOSE OBJECTS
- SHORT SIGHT
- SHORT SIGHT IS CAUSED BY AN EYEBALL THAT IS TOO LONG OR WEAK, IT CAN BE CORRECTED BY A CONCAVE LENS WITH DIVERGES THE LIGHT RAYS SO THAT THEY FOCUS ON THE RETINA
- SHORT SIGHTEDNESS IS WHEN YOU CAN SEE NEAR OBJECTS CLEARLY BUT NOT DISTANT ONES
- SHORT SIGHT IS CAUSED BY AN EYEBALL THAT IS TOO LONG OR WEAK, IT CAN BE CORRECTED BY A CONCAVE LENS WITH DIVERGES THE LIGHT RAYS SO THAT THEY FOCUS ON THE RETINA
