1. Lesson Starter List the organelles found in an animal cell
Give 3 examples of a specialised cell
What is the job of blood?
What types of cells are found in blood?

2. Learning Intention
To be able to identify the parts of the circulatory system
To be able to identify and explain the functions of different blood vessels

3. Cell Organisation Digestive Circulatory Respiratory Reproductive
Nervous

4. Cell Organisation (copy)
A TISSUE is a group of SPECIALISED CELLS working together to perform a particular function. ORGANS are composed of several tissues working together on one particular function; Organs work together in a SYSTEM.
Examples of systems include the digestive, circulatory, respiratory, nervous and reproductive system.

5. The Circulatory System
Oxygen, Carbon Dioxide
Dissolved food
Circulatory System carries around body to where needed

6. The Circulatory System
Heart- Pump
Blood Vessels (Veins, arteries, capillaries)- Tubes
Blood carried to every part of body

7. The Circulatory System (copy)
The circulatory system is composed of the heart, blood and blood vessels.
Its job is to transport essential substances like oxygen, glucose around the body.

8. The Heart
Muscular
Blood, Nerve, Muscle tissue
Pumps blood around body

9. The Heart https://www.twig-world.com/film/heart- 976/ Questions..
How big is the heart (roughly)?
Roughly how many times does the heart beat each day?
How many chambers does the heart have?
Why is one side of the heart shown to be blue and one shown to be red?
Why is one side of the heart thicker than the other?
What causes the sound of the heart beat?
Write questions on board before lesson; answer in jotters as they watch clip

10. The Heart
Questions..
How big is the heart (roughly)? – Roughly the size of your fist
Roughly how many times does the heart beat each day? – 100,000 times
How many chambers does the heart have?- 4 (2 atrium, 2 ventricles)
Why is one side of the heart shown to be blue and one shown to be red? – one side has oxygenated blood, one side deoxygenated
Why is one side of the heart thicker than the other?-
one side pumps blood to your full body
6. What causes the sound of the heart beat? –
the opening and closing of valves

11. The heart Flipped 4 Chambers Atrium collect blood
Ventricles contract and pump blood
Cardiac muscle
Right Atrium
Left Atrium
Right Ventricle
Left Ventricle

12. The Heart (copy)
The upper chambers are the right and left atria these collect blood.
The lower chambers are the right and left ventricles, these pump blood.
The wall of the heart is made of cardiac muscle.

13. The Heart Vena Cava- deoxygenated blood to the heart
Pulmonary Artery- carries blood from right ventricle to lungs
Aorta- the main artery of the body, supplying oxygenated blood to the circulatory system
Pulmonary Vein- receive oxygenated blood from the lungs
Aorta
Pulmonary Artery
Pulmonary Vein
Vena Cava

14. Valves prevent the backflow of blood to ensure blood keeps circulating

Valve

15. Circulation of blood through the heart
Blood high in oxygen is called oxygenated blood
Oxygenated blood returns from the lungs…
in the pulmonary vein
enters the left atrium
into the left ventricle
out through the aorta
to the body

16. enters the right atrium into the right ventricle
Blood low in oxygen is called deoxygenated blood.
Deoxygenated blood returns from the body tissues…
in the vena cava
enters the right atrium
into the right ventricle
out through the pulmonary artery
to the lungs where it picks up oxygen
