- B1(a)
- Diet and Metabolic Rate
- Carbs=energy
- Fats=Warmth+energy
- Protein=Growth+Cell Repair+Cell Replacement
- Fibre=Maintains Digestive System
- Vits+Mins=General Health
- Exercise=Higher Metabolic Rate
- Fighting Disease
- Pathogens=Microorganisms-Disease
- Bacteria=Very Small Cells-Reproduce Rapidly
- Damage Your Cells
- Produce Toxins
- Defence System
- Respiratory Tract
- Skin
- Hairs
- Mucus
- Platelets
- Help Blood To Clot Quickly
- To Seal Wounds
- Help Blood To Clot Quickly
- White Blood Cells
- Attack Invading Microbes By
- 1.Consuming 2.Producing Antibodes 3.Producing Antitoxins
- Attack Invading Microbes By
- Respiratory Tract
- Vaccination
- Protects From Future Infections
- Small amounts of dead of inactive microorganisms
- Carry Antigens
- Causes body to produce antibodies to attack them
- Carry Antigens
- Drugs
- Painkillers reduce the symptoms
- Antibiotics Kill the bacteria
- Doesn't destroy viruses
- Bacteria Can Become Resistant
- Mutations May Cause Resistance
- Resistant Bacteria Will Reproduce
- Mutations May Cause Resistance
- The Nervous system
- Sense Organs Detect Stimuli
- Stimulus=Change in Environment
- Eyes
- Sensitive to Light
- Ears
- Sensitive to Changes in Position
- Nose
- Sensitive To Chemical Stimuli
- Tongue
- Sense Organs Detect Stimuli
- Stimulus=Change in Environment
- Eyes
- Sensitive to Light
- Ears
- Sensitive to Changes in Position
- Nose
- Sensitive To Chemical Stimuli
- Tongue
- Tongue
- Sensitive To Chemical Stimuli
- Skin
- Sensitive to Touch, Pressure, Pain and Temperature Change
- Sense Organs Detect Stimuli
- Tongue
- Sensitive To Chemical Stimuli
- Skin
- Sensitive to Touch, Pressure, Pain and Temperature Change
- Nerve Cells
- Relay Neurones
- Carries Signals From Sensory Neurones to Motor Neurones
- Motor Neurones
- Carries signals from Central Nervous System to the Effector Muscles or Glands
- Effectors
- Muscles and Glands
- In Response to a Nervous Impulse:
- Muscles Contract
- Untitled
- In Response to a Nervous Impulse:
- Muscles and Glands
- Effectors
- Carries signals from Central Nervous System to the Effector Muscles or Glands
- Relay Neurones
- Plants
- Produce Hormones
- React to external Stimuli=Grow Towards Light, Water etc.
- Tropisms
- Positive
- Plant Grows Towards Stimuli
- Negative
- Plant Grows Away From Stimuli
- Phototropism=Light Stimulus
- Gravitropism
- Positive
- Produce Hormones
- Sense Organs Detect Stimuli
- Synapses And Reflexes
- Reflexes=Automatic Responses To Certain Stimuli
- Reflex Arc=Passage Of Information In A Reflex
- Neurones In The Reflex Arc Go Through The Spinal Cord
- When A Stimulus Is Detected, Impulses Are Sent Along A Sensory Neurone
- When The Impulses Reach A Synapse Between A Sensory and Relay Neurone, Chemicals Are Released
- The Impulses Then Travel Along The Motor Neurone To The Effector
- When The Impulses Reach A Synapse Between A Sensory and Relay Neurone, Chemicals Are Released
- Reflex Arc=Passage Of Information In A Reflex
- Reflexes=Automatic Responses To Certain Stimuli
- Hormones
- Hormones=Chemicals Released Into The Blood
- Carried In The Blood Plasma
- Produced By
- Ovaries (Females Only)
- Produce Oestrogen
- Ovaries (Females Only)
- Hormones=Chemicals Released Into The Blood
- The Menstrual Cycle
- Four Stages
- 1. Bleeding Starts, Uterus Lining Breaks Down-4 Days
- 2.The Lining of the Uterus Builds Up Again
- Ready To Receive a Fertilised egg
- 3.An Egg is Released
- 4.Wall Is Then Maintained
- 3 Main Hormones Involved
- FSH
- Causes an Egg to Mature
- Untitled
- Oestrogen
- LH
- FSH
- Four Stages
- Diet and Metabolic Rate
- Sensory Neurone
- Nerve Cells
- Relay Neurones
- Carries Signals From Sensory Neurones to Motor Neurones

- In Response to a Nervous Impulse:
- Muscles Contract
- Untitled
- In Response to a Nervous Impulse:
- Muscles and Glands
- Effectors
- Carries signals from Central Nervous System to the Effector Muscles or Glands
- Relay Neurones
- Carries Signals as Electrical Impulses From Receptors To The Central Nervous System
- Nerve Cells
- Synapses Connect Neurones
- Synapses And Reflexes
- Reflexes=Automatic Responses To Certain Stimuli
- Reflex Arc=Passage Of Information In A Reflex
- Neurones In The Reflex Arc Go Through The Spinal Cord

- When The Impulses Reach A Synapse Between A Sensory and Relay Neurone, Chemicals Are Released
- The Impulses Then Travel Along The Motor Neurone To The Effector
- When The Impulses Reach A Synapse Between A Sensory and Relay Neurone, Chemicals Are Released
- Reflex Arc=Passage Of Information In A Reflex
- Reflexes=Automatic Responses To Certain Stimuli
- Nerve Signal Transferred By Chemicals
- These Chemicals Set Off A New Signal In The Next Neurone
- Synapses And Reflexes
- The Pituitary Gland
- Produced By
- Ovaries (Females Only)
- Produce Oestrogen
- Ovaries (Females Only)
- Produce Many Important Hormones, Including FSH and LH
- Produced By
