An organ is a part of the body that does a particular job, such as the brain, heart and lungs.

The function of an organ is its job within the body.

The heart is an organ that pumps blood around the body.

Blood is pumped around the body by the heart.

A model is used to describe something that cannot be experienced directly.

In this Human circulatory system unit, pupils learn about the function of the heart, blood and blood vessels in humans. In the Breathing and respiration unit, they will build on this knowledge to learn about the lungs and breathing, including gas exchange in humans. 

In the Healthy eating unit, pupils learnt that animals, including humans, cannot make their own food; they get nutrition from what they eat. In this The human circulatory system unit, pupils will build on this knowledge to recognise ways in which nutrients and water are transported within animals including humans

This unit explores the human circulatory system, identifying the heart, blood vessels, and blood functions. It examines how diet, exercise, drugs, and lifestyle affect body function and details nutrient and water transport in animals. Emphasis is on data recording and presenting findings.

The human circulatory system

Blood is a liquid that travels around the body and transports oxygen, nutrients and waste.

The job that something does is its function.

Nutrients are substances that living things use to stay alive and healthy. Animals take in nutrients from their food.

Oxygen is a type of gas found in Earth's atmosphere that is vital for living things.

Carbon dioxide is a type of gas found in Earth's atmosphere.

Blood vessels are tubes through which blood flows around the body.

Arteries are blood vessels that carry blood away from the heart.

Veins are blood vessels that carry blood back to the heart.

Oxygenated blood is blood rich in oxygen.

Deoxygenated blood is blood low in oxygen.

Nutrients are important substances that living things use to stay alive and healthy.

When we digest food it is broken down so that nutrients can be used by the body.

The intestine is a long tube that is split into the small and large intestine, through which food travels from the stomach and out of the body while it is being digested.

Bloodstream is the flow or movement of blood throughout the body.

Blood vessels are tubes through which blood flows around the body

The circulatory system is a network of the heart, blood and blood vessels working together to circulate blood around the body

A flowchart is a diagram that shows the steps of a process from beginning to end

A draft is a detailed outline that provides the information you need to complete a task

The circulatory system is a network of the heart, blood and blood vessels working together to circulate blood around the body.

To present information is to show or share it with others.

A verbal presentation is in the form of spoken words.

A pictorial presentation is in the form of pictures.

The heart is a pump that pushes blood around the body.

A transplant is when an unhealthy organ is removed from the body and replaced with a healthy organ.

Pros and cons are arguments for and against something.

To research something is to find out about it or investigate it carefully.

A debate is a formal discussion about a subject where people have different views.
