What do cells do and become. What do these cells then form and then what do they form, to form what? What have different systems?
Cells differentiate and become specialised.These specialised cells form tissues, which form organs, which form organ systems. Large multicellular organisms have different systems inside them for exchanging and transporting materials.

What is a tissue?
A tissue (e.g, muscle tissue) is a group of similar cells that work together to carry out a particular function.
2 of 12
What is an organ?
An organ (e.g, the heart) is a group of different tissues that work together to perform a particular function.
3 of 12
What is an organ system?
An organ system (e.g, the circulatory system) is a group of organs working together to perform a particular function.
4 of 12
What is the heart part of?
The circulatory system.
5 of 12
What does the heart have? (1)
The heart has four chambers and four major blood vessels.
6 of 12
What does the right atrium of the heart receive? (2)
The right atrium of the heart receives deoxygenated blood from the body (through the vena cava)
7 of 12
What does the deoxyegnated blood move through to? (3)
The deoxygenated blood moves through to the right ventricle, which pumps it to the lungs (via the pulmonary artery).
8 of 12
What does the left atrium receive? (4)
The left atrium receives oxygenated blood from the lungs (through the pulmonary vein).
9 of 12
What does the oxygenated blood then moves through to? (5)
The oxygenated blood then moves through to the left ventricle, which pumps it out round the whole body (via the aorta).
10 of 12
What does the left ventricle have than the right? Why? (6)
The left ventricle has a much thicker wall than the right ventricle. It needs more muscles because it has to pump blood around the whole body, whereas the right ventricle only has to pump it to the lungs.
11 of 12
What do valves do? (7)
Valves prevent the backflow of blood.
