Final answer:
Collagen and Elastin are the two key elements in the extracellular matrix that resist stretching and offer resilience, with Collagen providing structural strength and Elastin giving tissues flexibility.
Step-by-step explanation:
The two components commonly found in the extracellular matrix that help resist stretching and provide resilience are Collagen and Elastin. Collagen is the most abundant protein in the extracellular matrix, providing strength and structure. Elastin, on the other hand, gives tissues their elastic properties, allowing them to return to their original shape after stretching or contracting.
Together, these components allow the extracellular matrix to fulfil its role of supporting the cells in a tissue, maintaining its shape, and facilitating communication between the cells, all the while enabling the tissue to endure mechanical stresses.
