Using blood
What are the arteries?
They are blood paths that take blood from the heart and to the organs. They are oxygen-rich and travels at high pressure. They have muscular walls to withstand the pressure.
What are veins?
Veins are blood paths that take blood from the organs to the heart. They have oxygen-poor blood and travels at low pressure. They have valves to prevent the backward flow of blood.
What are capillaries?
They are small vessels that allow the veins and the arteries to exchange substances.
What are the components in our blood?
Red blood cells
White blood cells
Platelets
Plasma

Certain types of blood cells fight infections in your body.
They produce memory cells that fight the infection quickly.

They carry nutrients, vitamins, hormones, red blood cells, white blood cells, and platelets to where they are needed.
They also carry waste products like carbon dioxide.
Name all the four chambers in the heart?
Right atrium
Right ventricle
Left atrium
Left ventricle
Explain the right atrium and ventricle?
The right atrium receives oxygen-poor blood and then pumps it into the right ventricle. Then the right ventricle pumps the blood into the lungs.
Explain the left atrium and ventricle?
The left atrium receives oxygen-rich blood and then pumps it into the left ventricle
Where is your heart located?
In your chest, behind your chest
How can you measure your heartbeat?
