A-LevelBiologyThe mitotic cell cycleOct/Nov 2018Paper 2 Q37 Marks
The response of the human body to tissue damage depends on the types of tissues involved. Epithelial tissue, liver tissue and cardiac muscle tissue each respond differently to damage. • Epithelial tissue of the gas exchange system contains stem cells. • Liver tissue contains cells in a non-dividing state that can enter a cell cycle when stimulated. • Cardiac muscle tissue contains cells that cannot divide at all. Damage is permanent and is associated with scar tissue formation.
