For our science lesson, we will start our topic of 'Staying Alive'. In this topic, we will look at animals including humans. We will focus in on what keeps us alive and what we need to do to stay alive and healthy. You will be building on knowledge from Year 4 in this unit. 



Do not forget to upload any work you wish to share onto Seesaw!





Create two headers in your book: 'What I know' and What I want to know'.


Underneath the first one, record anything you can remember about animals and humans. Consider what the word circulation might mean. e.g. the different types of animals, creatures who have a spine, anything you might know about the inner workings of your body. 


Underneath the second one, record any questions you wish to know the answer to for this topic. e.g. What keeps us alive? How can we stay healthy?



The Circulatory System


The circulatory system is one of the most important systems in the body. Made up of the heart, blood and blood vessels, the circulatory system is your body's delivery system. Your heart plays and important part in being healthy. It keeps all the blood in your circulatory system flowing. Blood helps oxygen get around your body. When you exercise you can feel your pulse, it tells you how fast your heart is pumping.


The body's circulatory system is responsible for transporting materials throughout the entire body. It delivers nutrients, water, and oxygen to your billions of body cells and carries away wastes such as carbon dioxide that body cells produce. It is an amazing highway that travels through your entire body connecting all your body cells.


At the centre of this system is the heart, an amazing organ. The heart beats about 3 billion times during an average lifetime. It is a muscle about the size of the fist. The heart is located in the centre of the chest slightly to the left. Its job is to pump blood and keep the blood moving throughout the body. The blood is pumped around a complex network of blood vessels extending to every part of the body.


Blood carries the oxygen and nutrients needed to fuel the activities of the body’s tissues and organs, and it plays a vital role in removing the body’s waste products. An average-sized adult carries about 5 litres (9 pints) of blood.
