What I should know or be able to do
The human body is made of systems
Each system is in turn made up of organs
Some systems are the digestive, muscular, circulatory, and
nervous and respiratory systems.
State the name of one organ each from the digestive,
muscular, circulatory, nervous and respiratory systems
Give the functions of the digestive, muscular, circulatory,
nervous and respiratory systems
The Heart
The heart is made of muscle
The heart pumps blood around the body
The ribcage helps to protect the heart
The heart has 4 chambers
Valves stop the blood flowing in the wrong direction
A vein called the vena cave returns blood to the heart
An artery called the aorta takes blood away from the heart
The left side of the heart contains oxygenated blood
The right side of the heart contains deoxygenated blood
A stethoscope is used to listen to the heartbeat
I can explain how to listen to a person’s heart using a
stethoscope
The heart rate and the pulse rate have the same value
The heart rate changes with activity
I know about arteries, capillaries and veins
A sphygmomanometer is used to measure blood pressure
I can explain how to measure blood pressure using a digital
sphygmomanometer
Blood pressure is caused by the pressure of the blood from
the heart entering the arteries
A defibrillator is a machine that gives the heart an electric
shock
If a heart stops beating, a defibrillator restarts it

What I should know or be able to do
The Lungs
The lungs are protected by the ribcage
The lungs take in oxygen from the air and give out carbon
dioxide
The windpipe takes the air into and out of the lungs
The bronchi link the windpipe to the lungs
In the air sacs, oxygen leaves the lungs and enters the blood
and carbon dioxide enters the lungs from the blood
The diaphragm helps to move air into and out of the lungs
The Skin
The skin helps to protect the skin from the harmful effects
of UV light
Teeth
Four types of tooth are incisors (for biting food), canines,
premolars and molars (for grinding food).
The parts of a tooth are an outer layer of hard wearing
enamel, dentine and a pulp cavity with nerves and blood vessels
Know the position of the different kinds of teeth in the mouth
Plaque is a layer of bacteria that forms over teeth
Plaque forms acid from sugary food
Acid destroys tooth enamel, causing cavities
Know how to keep your teeth healthy
Muscles
One muscle closes the elbow joint, a different muscle opens it
Muscles work by contraction
Muscles can tire
Training can make muscles stronger
Brain
The parts of the brain are: medulla, cerebrum and cerebellum
The cerebrum is for conscious thought
The cerebellum controls balance and muscle coordination
The medulla controls heart rate and breathing rate.
Describe the sequence of a nervous pathway from stimulus to
response

What I should know or be able to do
A reflex action is a fast response that protects you from
harm
Examples of a reflex action are blinking, pulling your hand
away from a hot object, sneezing
Other things I have learned in this topic:
Health
To value and look after my health
How a person can avoid having heart attack
How to protect my skin from the harmful effects of UV light
How to look after my teeth
Skills I may have developed in this topic :
Practical skills
Making hypothesis
Planning experiments
Setting up and carrying out experiments
Drawing conclusions from experimental results
Evaluating the fairness and validity of practical work
Drawing tables
Drawing Line Graphs
Working as part of a team
Contributing to group/team discussions
Simple arithmetic calculations
