What role do tendons play in the muscular system?

Tendons play a crucial role in the muscular system by connecting muscles to bones. When a muscle contracts, it pulls on the tendon, which in turn pulls on the bone, allowing for movement of the skeleton. This connection is essential for facilitating voluntary movements, such as walking, running, and lifting. Tendons are made of strong, flexible connective tissue that can withstand the forces exerted by muscle contractions. The efficiency and effectiveness of movement depend significantly on the proper functioning of tendons as they provide the necessary link between muscle and bone.

The other options pertain to functions that are not related to the role of tendons within the muscular system. Supporting blood flow relates to the circulatory system, regulating hormone levels is a function of the endocrine system, and facilitating food absorption pertains to the digestive system. Each of these systems operates independently of the muscular system's role in movement and structural stability.
