1. The Cardiovascular System

2. Learning objectives
Name the different blood vessels and understand their function
Name the two circuits of the cardiovascular system and explain them

3. The cardiovascular system us made up of three main parts:
The heart
The blood
Blood vessels

4. Two main types of blood vessel:
Arteries – carry blood Away from the heart
Veins – which carry blood towards the heart
Visits

5. Controlling body temperature.
What is the purpose of the cardiovascular system?
Transporting substances around the body. These include oxygen, glucose, carbon dioxide, nutrients, water and waste products.
Controlling body temperature.
Protecting the body. Blood contains cells and anti-bodies that fight infection and clotting agents to stop bleeding.

6. ? Basis behind the cardiovascular system ?
Discuss what this diagram means…. ?

7. The heart has two circuits
Systemic circuit - body circuit – carries:
Oxygenated blood around the body in the arteries
Deoxygenated blood back to the heart along the veins
Pulmonary circuit– Lungs – carries:
Deoxygenated blood from the heart to the lungs to be oxygenated
The blood then goes back to the heart through veins to be oxygenated – which will then be pumped to the body circuit

9. Watch the following video
