• 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
• 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.
