2. • Cells in organisms
become specialised
to perform certain
functions
• If similar cells work
together they form a
tissue
Cardiac Muscle Tissue
• These cardiac(heart) muscle cells
are all the same
• They work together, forming
cardiac muscle tissue
3. • Tissues work together
to perform a specialised
function
• They form an organ,
like the heart
• The heart is made of
cardiac muscle tissue,
connective tissue and
nerve tissue
This is a sheep’s heart cut open.
Look at the different types of
tissue present.
4. • Various organs work
together forming an
organ system
• The heart works with
the blood vessels and
the blood forming the
circulatory system
5. Organism
• Organ systems make up
organisms!
• Over the next two years
